Chapter 3: Description and Theory of Operation

3.1 BiPAP Vision Ventilatory Support SystemThe BiPAP Vision is a microprocessor-controlled, positive pressure ventilatory assist system. Thesystem’s integral air intake filter draws in ambient air which is then pressurized by the system’s centrifu-gal blower assembly. The In-Line Flow Restrictor (ILFR) valve and Pressure Regulation Valve (PRV),which are both located in the blower discharge airway, regulate total flow and pressure at the blowerdischarge system. An oxygen module can be installed to add a controlled source of supplemental oxygen,up to 100%, to the patient.

The Pressure Control (PC) board continuously monitors the readings from the Airflow Module (AFM) oftotal gas flow, temperature, generated pressure, and patient circuit pressure to ensure prescribed therapyto the patient. The PC board transmits process data to the Main Control (MC) board which then providesoverall control of the BiPAP Vision, including conveying instructions to the PC board regarding requiredvalve stem position and blower speed.

The unique design and operation of the ventilator makes it especially suited for mask applications.Designed with the BiPAP Auto-Trak SensitivityTM feature that automatically adjusts to changing circuitconditions, the ventilator is capable of ensuring optimum patient-ventilator synchronicity despite changesin breathing patterns and circuit leaks. (Refer to the BiPAP Vision Clinical Manual.)

A liquid crystal display (LCD) screen is mounted on the front enclosure of the BiPAP Vision. The LCDand the Display Control (DC) board provide the primary user interface with the ventilator, including thevisual presentation of data, control features, and visual and audible presentation of alarm conditions. Theuser interacts with the ventilator through the touch pad and rotation of the rotary encoder while observ-ing the results of this input on the display. The information provided on the display varies depending onthe state of the ventilator and / or the operations being performed.

The BiPAP Vision incorporates a number of safety features and self-diagnostic systems. System internalfunctions are checked automatically at start-up, and periodically throughout normal operation. Anaudible and visual alarm announces failures of principal subsystems. Integrated patient alarms are alsoprovided and are announced on a visual message display area as well as with an audible tone.

The following sections of this chapter describe in more detail the major subsystems and components thatmake up the BiPAP Vision and its basic theory of operation.



1045049

Function

PSS The Power Supply Subsystem (PSS) provides DC power to the BiPAP Visionfrom an AC source.

MC The Main Control (MC) board or Main Control Subsystem (MCS) performs all control,or data acquisition, and calculations required for the user-selected parameters. In addition,MCS the MC performs the start-up test and reports all errors.

PC The Pressure Control (PC) board or Pressure Airflow Subsystem (PAS) controls the bloweror and valves to generate and regulate the system pressure. The PAS senses the outletPAS pressure and the patient pressure and regulates the outlet pressure to the patient circuit.

DC Through the touch pad, the Display Control (DC) board or Display/Controlor Subsystem (D/CS) evaluates user inputs and passes valid parameters to the MC. The DCD/CS receives display data from the MC. The DC also has its own internal functions; the

results of which are reported to the MC.

AFM The Airflow Module (AFM), including the mass airflow sensor in the airstream,provides an airflow measurement interface to the PC, allowing the PC tomeasure total flow, temperature, and system pressure.

ILFR The In-Line Flow Restrictor (ILFR) valve assembly regulates the total flowfrom the blower discharge.

PRV The Pressure Regulation Valve (PRV) assembly is opened during exhalation toallow the patient flow to be exhausted.

OM The Oxygen Module (OM) subassembly regulates and proportions the oxygen releasedinto the air from the blower according to the oxygen concentration level set on theparameters screen.

3.2 Power Supply Subsystem (PSS)The PSS supplies the Main Control (MC), Pressure Control (PC), and the Display Control (DC) with theproper DC supply voltage. Safety features designed into the circuitry include an overvoltage disconnect,low voltage supply detect, and line loss detect. Other features include “power-on” indicator voltage,circulation fan power, and an On/Off switch connection.

Figure 3-2 PSS Block Diagram



1045049

3.2.1 Input Range

The BiPAP Vision can operate with an AC input of 100, 120, 230, or 240 VAC (±10%) depending on themodel.

3.2.2 DC Supply

The output DC supply is fused at 30 amps and delivers between 20.6 VDC and 35 VDC with a maximumripple of 1 vpp (peak-to-peak voltage) to the MC, PC, and DC.

3.2.3 Overvoltage Disconnect

The overvoltage disconnect is used to remove the DC supply output when it exceeds 36 VDC and recon-nects it when the level returns to an acceptable value.

3.2.4 AC Fail

The MC module monitors the level of DC supply voltage and the AC voltage output from the transformersupply winding to determine if an AC fail condition exists.

Low DC supply detect – If the DC supply voltage drops to 19.38 VDC or lower (nominal), an AC failcondition will be triggered.

Line loss detect – The AC voltage output from the transformer supply winding is monitored for a loss-of-cycle condition. Both legs of the winding are input to the monitoring circuitry. Whenever AC is lost, theAC fail signal is activated.

3.2.5 Outputs

The PSS module also includes the following:

a. Front panel “power-on” indicator voltage (J5)

b. Circulation fan power (J4)

c. On / Off switch (part of J2)

d. Circulation fan current sense information to (J12) on the PC subsystem.

3.4.1 Microcontroller Interface

Programmable Array Logic (PAL) memory device decodes the chip selects in such a way that the pro-gram code is retrieved from the EEPROM and data is retrieved from the RAM. An additional PALprovides the interface for the Intermodule Communications Bus (ICB). The microprocessor monitors:oxygen and gas temperatures; Airflow Module (AFM) and Oxygen Module (OM) detection; In-Line FlowRestrictor (ILFR), Pressure Regulation Valve (PRV), and oxygen valve DAC control voltage; blower DACcontrol voltage; and power supply and reference voltages.

3.4.2 Blower Motor Drive

The complete motor controller includes closed loop speed control via analog circuitry. When the desiredspeed and actual speed are known by the processor, the speed is adjusted by increasing or decreasing theDAC converter output to achieve proper pressure and flow.

3.4.3 Pressure Regulation Valve (PRV) and In-Line Flow Restrictor(ILFR) Drives

The valve drives have closed loop control via the microprocessor. The microprocessor reads sevenpressure, flow, and temperature sensors through the PC hardware, and receives prescription parametersfrom the MC. The microprocessor then adjusts analog DAC voltages to control the PRV and ILFR valvesas required to meet the prescription.

3.4.4 Pressure Sensors

The PC module has two dual pressure sensors (MT1 and MT2) and a single sensor (MT3). They measurepatient pressure, unit outlet pressure, and barometric pressure. These sensors are subject to calibrationwith their calculated slope and intercept values stored in the on-board EEPROM. MT3 is a backup outletpressure sensor that provides a redundant check of the primary outlet sensor located on the AFM.

NOTE: Calibration is factory programmed and field adjustment is not required.

3.4.5 Error Line Control (ELC) Circuit

The ELC circuit is designed to simply detect a failure from, or signal a failure to, the MC and DisplayControl (DC) modules. If the ELC line activates, only a power On / Off of the ventilator can clear thislatched circuit state.

3.4.6 Diagnostics Connector

The diagnostic connector (J3) interfaces with the microprocessor to view PC functions and system errorson units from serial number 100500 to 105999, unless upgraded. For units greater than this, the diagnos-tic connector is on the rear of the unit.

Pressure Control Subsystem (PC) (Continued)



1045049

3.5 Display Control Subsystem (DC)The DC provides a means of displaying the operating mode, measured and calculated operating param-eters, parameter setpoints, alarm limits, real-time graphics, and general status information. The DC alsoprovides the necessary user interface controls to modify the operating mode, parameter set points, alarmlimits, and graphical scales; and to reset or silence the audible alarm, and freeze or unfreeze graphics.The displays and controls are described in more detail in the following subsections.

3.5.1 DC/DC Converter

The DC/DC converter reduces the +24 VDC bulk supply to a +5 VDC logic level. (S/N <106K)

3.5.2 Display Backlight and Contrast Adjustment

A serial 8-bit D/A converter provides two, 0 to +5 VDC which originate in the MCU for these controls.

3.5.3 Display Voltage DC/DC Converter

This adjustable negative voltage converter reduces the level of bulk supply voltage needed to operate theLiquid Crystal Display (LCD) contrast control.

3.5.4 Cold Cathode Fluorescent Tube (CCFT) Inverter

The DC design has a DC to AC inverter that typically provides 390 VAC to the fluorescent tube in thedisplay through (J2). The current varies to adjust the brightness of the fluorescent tube.

3.5.5 Reference Voltage Checks

This circuit compares reference voltages to determine if they are at the appropriate level.

3.5.6 Power Failure Alarm Battery Enable

This control detects a power failure from the DC supply.

3.5.7 Alarm Battery Voltage Cutout/Check

The battery voltage cutout /check monitors the battery voltage level and cuts it out if it drops to a level ofapproximately 3VDC.

3.5.8 Backup Battery/Charger

The DC contains a 3.6 V nickel cadmium rechargeable battery that operates the audible and visual alarmindicators for at least 20 minutes, when fully charged, when the Error Line Control (ELC) is active, andthe DC supply has been removed. The battery output is compared to a reference voltage and the batteryis recharged as required through a charging circuit. If necessary, refer to page 5-12 to recharge thebattery.

3.5.9 Check Ventilator Light Emitting Diode (LED) Enable CurrentCheck

An internal test is performed to verify that the Check Ventilator LED current is acceptable.

3.5.10 Vent Inop LED Current Check

An internal test is performed to verify the Ventilator Inoperative LED current is acceptable.

3.5.11 Error Line Control (ELC) Circuits

The DC contains redundant error signaling circuitry to communicate error conditions among the sub-systems. The circuitry’s redundant and diverse nature minimizes the chance of communication failures.

Display Control (DC) (Continued)



1045049

3.5.12 Error LED

The error LED indicates that an error condition was detected, and it illuminates to make unit diagnosiseasier.

3.5.13 Diagnostic Interface

The diagnostic connector interface (J5) interfaces with the MCU to provide a means for the DC to down-load diagnostic data to a terminal or PC.

3.5.14 EEPROM

A serial EEPROM stores the setpoints for the backlighting and contrast and also for the appropriatediagnostic data.

3.5.15 LCD Controller

The DC circuit contains an LCD controller that interfaces with the display.

3.5.16 Debouncing / Keypad Matrix

The matrix keys are debounced and then the microprocessor scans the matrix to determine what key wasdepressed.

3.5.17 Rotary Encoder Control

The rotary encoder control circuit detects relative position, direction, and speed of the rotary encoder, allwithin one detent of movement.

3.5.18 Audible Alarm Activation

The audible alarm is activated by either an input from the ELC, the power fail circuitry, or the test alarmsignal from the MCU. It will also occur when the wrong key has been depressed, an adjustable parameterhas reached its limit, or the error signal has been activated.

3.5.19 Audible Alarm Current Check

An internal test is performed to verify the audible alarm current is acceptable.

3.5.20 “Power-on“ in Safe State

The DC contains circuitry that causes the hardware to “power-on” in a safe state; which is when thebacklight is off, the display is off, and the Intermodule Communications Bus (ICB) is terminated. Whenthe MCU determines that no Vent Inop error exists, it lets the unit resume operation under normaloperating conditions.

3.5.21 Watchdog and Low Voltage Reset

The watchdog function has to be periodically reset by the microprocessor if a time-out period has beenexceeded. This function is designed to reset the processor if the software gets lost. When a low logic levelis detected, the ELC will be activated resulting in a system shutdown.

Display / Control Subsystem (D / CS) (Continued)



1045049

3.6 Airflow Module (AFM)The AFM is a submodule of the Pressure Control (PC). The AFM receives power from the PC and pro-vides the following analog signals to the PAS:

a. Gas flow indication

b. Pressure indication

c. Temperature indication

To provide indications accurate enough for system requirements, the AFM must be calibrated. Calibra-tion data is stored in a nonvolatile memory that is part of the AFM. The flow, pressure, and temperatureindications are for the ventilator gas stream flowing through a “flow body” attached to the AFM circuitboard.

3.6.1 Flow Body

The flow body, with laminar flow element, is added to the ventilator gas stream, creating a small pressuredifferential to short a fraction of the flow through the AFM sensor. Inlet, outlet, and pressure ports arepart of the flow body for tubing attachment to the AFM electronic sensors. Also, a hole is molded into theflow body to position the temperature sensor. The body has molded feet for attaching it to the AFMcircuit board assembly.

Figure 3-6 AFM Block Diagram

And/Or Oxygen Supply



1045049

3.6.2 Analog Reference

The PC provides the AFM with power in the form of +12 VDC, –12 VDC, analog ground, +5 VDC, anddigital ground. An analog voltage reference supply is derived from the +12 VDC to power the pressureand flow sensors so their bridge outputs can be factory calibrated.

3.6.3 Flow Indication

Total gas flow indication is provided by MT1. It is then amplified by an instrumentation amplifier, low-pass filtered, and sent to the PC board for conversion.

3.6.4 Pressure Indication

MT2, a precision compensated pressure sensor, provides unit outlet pressure indication. The sensor isfollowed by a low-pass filter and a differential amplifier, and then sent to the PC board for conversion.

3.6.5 Temperature Measurement

The temperature is measured using a sensor inserted into a molded hole in the flow body. The BiPAPVision requires temperature indication to correct air density and detect an undesirable temperature rise inthe patient circuit.

3.6.6 Calibration

A data acquisition system, operating on a personal computer, is the control platform for AFM calibrationof temperature, pressure, and flow. Correction factors are derived and stored in the AFM module in anEEPROM, with calibration accomplished by balancing the flow transducer bridge with an EEPOT. ThePAS uses temperature, pressure, and flow to correct for actual operating conditions. Once calibrated, theAFM is interchangeable with other AFM assemblies.

NOTE: Calibration is factory programmed only.

3.6.7 Module Detection

The PC must know the AFM is connected, since it is required for normal operation of the ventilator. Anextra line pulls a PC microcontroller line near zero volts. If the line is above two volts, the AFM is notconnected, and the PC will transition to the error state.

3.7 Oxygen Module (OM)The OM is an optional submodule of the Pressure Control (PC). It receives power from the PC andprovides an analog signal to the PC for oxygen flow indication. To provide indications accurate enoughfor system requirements, the OM must be calibrated. Calibration data is stored in a nonvolatile memorythat is part of the OM. The flow indication is for the ventilator pure oxygen stream flowing through a flowbody attached to the OM circuit board.

3.8 Description of Ventilator ModesThe BiPAP Vision comes standard with two operating modes: Continuous Positive Airway Pressure(CPAP) and Spontaneous/Timed (S/T). A third, optional, Proportional Assist Ventilation/Timed (PAV/T) is also available.

3.8.1 Continuous Positive Airway Pressure (CPAP)

CPAP provides a constant pressure level delivered over the complete range of the patient’s spontaneousbreathing cycle. Pressure is controlled and maintained. Flow is available to meet changing patientdemands and automatically compensate for leaks. The mode delivers the prescribed level of pressurethat has been set with the CPAP control (Range: 4 to 20 cm H2O).

3.8.2 Spontaneous/Timed (S/T)

The S/T mode provides either pressure support during spontaneous breaths or time-triggered, pressure-limited, time-cycled machine breaths.

Spontaneous Breaths

Two pressure levels are set: an EPAP level (range 4 to 20 cm H2O) to establish a baseline pressure and anIPAP level (range 4 to 40 cm H2O) that determines the amount of pressure support delivered with eachbreath (PS = IPAP– EPAP). During the inspiratory phase, the BiPAP Vision responds as necessary tosatisfy the patient’s flow requirements while maintaining the preset IPAP pressure. Under these condi-tions, the patient is active in determining inspiratory time and tidal volume. The delivered tidal volumewill be dependent upon the pressure differential between the IPAP and EPAP levels, patient effort, andthe combined resistance and compliance of the circuit and the patient. If the patient does not activelyparticipate, the BiPAP Vision responds appropriately.

Timed Breaths

The S/T mode can also provide a time-triggered, pressure-limited, time-cycled machine breath, when thespontaneous respiratory rate drops below the Rate control setting. If the ventilator does not detect aspontaneous trigger within the interval determined by the Rate control setting, it will activate a time-triggered machine breath and deliver the IPAP level. Machine breaths are not synchronized with patienteffort, and once triggered to IPAP, the balance of the cycle is determined by the Timed Insp. Controlsetting. A maximum Timed Inspiratory setting of 3.0 seconds can be set, as long as the I:E Ratio does notexceed 1:1, as determined by the Rate setting. For example, see Figure 3-12. If the Rate control is set at 10BPM, the total respiratory cycle is six seconds. If a spontaneous trigger occurs before the six-second cycletime has elapsed, a spontaneously-triggered, pressure support breath occurs, a timed trigger will notoccur, and the timer is reset for a new six second interval. If a six second interval passes without aspontaneous trigger, a timed trigger will be initiated and IPAP will be delivered for the duration of timeset by the Timed Inspiration setting.

3.9 Nurse Call/Remote Alarm Feature Operation (for s/n unitsgreater than 106000 only)

The unit will activate a remote signal for system shutdowns, patient alarms, and Loss of AC Power condi-tions which inhibit therapy. Note that a Check Vent condition does not activate the nurse call signal. Thenurse call signal can be silenced via the Alarm Silence key for the same amount of time that the audiblealarm on the Vision is silenced (two minutes). The signal can also be cleared by selection of the AlarmReset key. The nurse call signal will automatically terminate when a patient alarm self-cancels.

The Nurse Call/Remote Alarm feature is meant to be a backup with the main Vision alarm system beingthe primary alarm/alert mechanism.

The Nurse Call or Remote Alarm signal is generated on the MC board and then can be connected to ahospital nursing station. This signal is opto-isolated and used to switch a relay to provide open or closedcontacts to the remote station circuit. The arrangement of the two jumpers (JP1 and JP2) on the MC deter-mine the output configuration that is utilized by a common connector on the rear panel of the Vision.

The Nurse Call Adapter (RI P/N 1014280) along with the Nurse Call Cable (RI P/N 1003742) can be usedto connect the Vision to a Nurse Call station.

The jumper configuration on the MC circuit board can be selected to meet requirements according to thefollowing table. Refer to the photo for jumper location.

3.10 BiPAP Vision Patient Disconnect Alarm Description ofOperation

The patient disconnect alarm (“Disconnect”) is based on the flow limit control algorithm in the Vision. The mitiga-tion for the Disconnect alarm is to put the unit into flow limit control. This same action is done when the user selectsthe Standby key.

3.10.1 Detection

The unit determines that a patient is not connected to the circuit anymore based on flow for the given pressure. Thisis implemented via a look-up table, with a flow entry for every generated pressure. The range of flows is 95 to 180LPM, with 180 LPM being the low limit for any pressure above 9 cmH2O. If the unit detects flow greater than thethreshold at any given pressure for more than 10 seconds (3 seconds in for software earlier than 13.2), the unit putsitself into the Flow Limit Control state. In this state, the unit attempts to limit the flow coming out of the mask inorder to make putting the mask back on the patient easier and more comfortable for the patient.

Also, for safety concerns, the oxygen valve closes to discontinue oxygen delivery during this condition.

When the Standby key is selected by the user, the unit automatically enters the FLC state, regardless of the flow atthe time the Standby key is selected.

In order to limit the flow, the unit drops the pressure to 4 cmH2O. The algorithm was enhanced to work with the FullFace Mask a while ago. The Full Face Mask has a flap that will close the patient circuit and open the mask toatmosphere upon loss of flow and pressure. This flap must be kept in a position during FLC so that the patientcircuit is not occluded. This allows the unit to detect when the patient is reconnected. The enhancement to thealgorithm consists of the pressure being slowly increased to keep the flow at 160-170 LPM. The pressure level islimited to 10 cmH2O for software 11.2 and 11.3 (15 cmH2O for software 11.3a and higher), regardless of how muchflow is being generated. Therefore, the unit will either output 160-170 LPM at some pressure or will be limited tosome lesser flow at 10 cmH2O for software 11.2 and 11.3 (15 cmH2O for software 11.3a and higher).

3.10.2 Termination

There are two termination stages to FLC. During the first stage, as the pressure is being increased from 4 cmH2O toits maximum of 10 cmH2O for software 11.2 and 11.3 (15 cmH2O for software 11.3a and higher), FLC will beautomatically terminated if the unit detects negative flow (i.e., the patient breaths back into the unit). This pressureincrease takes about 10 – 12 seconds for software versions earlier than 13.2, depending on how soon the flow setpoint is reached. There have been two enhancements in software version 13.2 in this area. The first is that thepressure is increased faster (1 cmH2O per 40 ms instead of the previous ¼ cmH2O per 40 ms) to shorten the amountof time in stage one. The second change concerns the flow range processing. In software versions earlier than 13.2,when the pressure is dropped to 4 cmH2O and the flow is greater than the desired flow range (160-170 LPM), theflow limit algorithm attempts to decrement the pressure to get the flow into that desired range. In software version13.2, that was changed to immediately enter stage 2 under that condition.



1045049

Once either the flow set point or the maximum pressure is reached, the unit will automatically terminateFLC for either the detection of negative flow or if flow varies from the current flow by more than 40 LPMin software versions prior to 13.2 and 20 LPM for software version 13.2. For instance, if the 160-170 LPMset point has been reached, the unit will terminate FLC if the flow drops below 120 LPM or goes above210 LPM in older software and 140-190 LPM in the new software.If the flow set point has not been reached, the current flow at 10 cmH2O for software 11.3 and 11.3 (15cmH2O for software 11.3a and higher) is used as the set point. For instance, if only 80 LPM can bereached at 10 cmH2O for software 11.3 and 11.3 (15 cmH2O for software 11.3a and higher), the thresholdsfor automatic termination of FLC will be 40 LPM and 120 LPM in older software and 60-100 LPM in newsoftware.

This allows FLC to be terminated without the patient necessarily breathing back into the machine but bythe simple act of refitting the mask to the patient.

The Standby condition, besides being terminated automatically by the above methods, can also bemanually terminated by reselecting the highlighted Standby soft key on the Monitoring screen.

When FLC is terminated during a “Disconnect” alarm period, the alarm is self-cancelled. That meansthat the audible component of the alarm is silenced but the visual component of the alarm remainsdisplayed on the screen. That can be cleared by selecting the Alarm Reset key.

Note: During FLC, the oxygen parameter setting reduces to 21%, regardless of the setting.

1045049

5.8 Internal Alarm Battery

5.8.1 Battery Function

The BiPAP Vision contains an internal NiCAD battery located on the DC (P/N 1012819) to activate theVentilator Inoperative visual and audible alarm indicators if an error occurs. A fully charged battery canmaintain the audible alarm for up to 20 minutes.

5.8.2 Low Battery Condition

The NiCAD battery can lose its charge if the BiPAP Vision is not used for an extended time. In a typicalenvironment, a fully charged battery can be stored approximately six months before losing its charge, butthe discharge rate depends heavily on temperature.

NOTE: The BiPAP Vision internal alarm battery should be charged prior to use if it has beenstored for longer than three months.

If the battery voltage is too low to support the alarm indicators, the Check Ventilator visual (Eye icon) andaudible alarm indicators will activate. The time that the audible alarm operates may be short due to thelow voltage of the battery. The BiPAP Vision also generates error code 205.

To check the error code:

Step 1 Silence the audible alarm component by pressing the Alarm Reset key.The audible component will not sound again.

Step 2 Press the Monitoring hard key if you are not already in the Monitoring screen.

Step 3 Press the Options soft key.

Step 4 In the Options screen, press the Error soft key.Check vent error codes are displayed in the top line of the Options/Message area.



1045049

5.8.3 Charging the Internal Battery

There are two methods used to recharge the NiCAD battery on the DCS circuit board that is used to sound theaudible alarm, fast charge and normal.

1. Fast Charge Method (Check Vent/Error 205 Being Displayed)

A fast charge will be initiated at first time initialization and when a low internal battery error is detected. Fast chargingis available when the unit is in the Setup Screen and when it is providing therapy (i.e., the unit can sit in the diagnos-tic mode and still fast charge). Fast charge time is 6 hours to sufficiently charge the battery to support the audiblealarm for 20 minutes.

If the unit is powered off during a fast charge sequence, the sequence will pick up where it left off when the unit ispowered back on unless a low battery error is detected during the start-up testing (i.e., the unit was off long enoughto discharge the battery). In that case, a new 6-hour fast charge sequence will be initiated. The functionality of theCheck Ventilator error 205 remains unchanged - the error code will be able to be cleared approximately 1 minute afterthe status indicates a good battery.

Note: If the status never indicates a good battery (i.e., the battery is actually bad and will not take a charge),the fast charge sequence will run continuously. The user will be able to detect this by not being able toclear the 205 error even after a full fast charge cycle.

Charging Process:

1. Remove the unit from patient use.2. Plug the unit into an AC source and start the unit. The Self Diagnostics will begin.3. Allow the unit to remain in the Exhalation Port/Language Screen.4. Or, allow the unit to be in therapy or Standby mode. Press the alarm reset to silence the audible alarm.5. Leave in one of these conditions for approximately 6 hours to fully charge the battery.

2. Normal Method (No Check Vent/Error 205)

If there is no Check Vent error 205, the charging circuit will continue to charge the battery on a regular basis while inthe Test Exhalation/Language screen or during therapy use. It will take approximately 24 hours to fully charge thebattery to support the audible alarm for up to twenty minutes.

Charging Process:

1. Remove the unit from patient use.2. Plug the unit into an AC source and start the unit. The Self Diagnostics will begin.3. Allow the unit to remain in the Exhalation Port/Language selection screen.4. Or, allow the unit to be in therapy or Standby mode.5. Leave in one of these conditions for approximately 24 hours to fully charge the battery.

Internal Alarm Battery Maintenance (Continued)



1045049

Charging Verification:

1. A minimum of two hours is required to charge a fully discharged battery to a voltage at which the alarm willnot be activated. At this time, the unit can be operated and will continue to trickle charge the battery while it isin operation.

2. Press Monitoring to begin operation.3. Wait two minutes to determine if the Check Vent alarm activates with an error 205 in the Error Message screen.

If not, then the unit is ready for use.

CAUTION: Prolonged storage of the BiPAP Vision at high temperatures, above 80 ºF (27 ºC) canresult in premature battery failure. Failure to recharge a battery when it is being stored forlong periods will cause a loss of battery life, activate the Check Ventilator alarm, andgenerate error code 205.

6.1 Overview

Purpose

This chapter outlines a general procedure for troubleshooting the BiPAP Vision. Problems shall be investi-gated to the major component or subassembly as indicated on the specific error code charts found in thischapter.

Process

Step 1 If a Patient Alarm activates and it is not possible to eliminate it, refer to the AlarmDescriptions beginning on page 6-8 for detailed descriptions, possible causes, and correctiveaction.

Step 2 If the Check Ventilator icon illuminates along with the audible alarm, refer to the CheckVent Error Flow Chart on page 6-12 for the recommended troubleshooting sequence tofollow. Refer to the “Check Vent” Error Codes chart on page 6-13 for descriptions andpossible corrective actions.

Step 3 If the Ventilator Inoperative icon illuminates along with the audible alarm, refer to the VentInop Errors Flow Charts on pages 6-14 and 6-15 for the recommended troubleshooting

sequence to follow. Refer to the Common System (page 6-16), PC Specific (page 6-18), MCSpecific (page 6-22), and the DC Specific (page 6-24) Error Codes Charts for descriptions andpossible corrective actions.

Step 4 Use the chart on page 6-3 to diagnose Common System Level Problems.

Step 5 Use the “Error Codes Chart Abbreviation Definitions” on pages 6-25 and 6-26 for thedefinition of terms used throughout all of the Error Code Charts.

Step 6 Follow the PC/Laptop Setup Procedures in section 8.9 for the suggested method to check the error code for each subsystem. The procedure includes PC/Laptop setup guidelines.

6.2 Description of System AlarmsThe BiPAP Vision incorporates self-diagnostic testing capabilities and a number of safety features. Allsystem internal functions are checked automatically at start up and periodically throughout operation. Themicroprocessors continuously obtain readings from internal sensors to monitor machine functions andoperating conditions. Device malfunctions or abnormal operating conditions are analyzed and reportedaccording to the level of severity. Two primary alarm functions, Check Ventilator and Ventilator Inopera-tive, are available to identify a system malfunction. Patient Alarms are displayed on screen when activated.

All alarms contain an audible and visual element. In the event of an alarm condition, the audible alarmsounds and the screen changes to show the alarm condition in the Mode/Message Area. See Figure 6-1.

6.2.2 Patient Alarm Silence and Reset

The audible indicator of most alarms is self-cancellable if the patient alarm condition is corrected. The usercan silence the audible indicator by pressing the ALARM SILENCE hard key. The ALARM SILENCE hardkey turns off the audible alarm for two minutes. Additional pressing of the ALARM SILENCE hard key hasno effect on the alarm. When the alarm silence is active, the message “Alarm Silenced” appears in theMode / Message Area for the duration of the silence period. Any new alarm condition that occurs, exceptfor an Apnea alarm, during the silence period will provide a visual alert, but will not trigger the audiblealarm.

The visual patient alarm indicator in the Mode / Message Area is cancelled only when the ALARM RESEThard key is pressed. The ALARM RESET hard key cancels the alarm silence period and resets the visualindicators. The alarm immediately reactivates if the condition causing the alarm has not been corrected.

6.3 Alarm Indicators

6.3.1 Vision Ventilator Inoperative Indicator

Purpose: Alerts the user to a machine malfunction byilluminating the red “Wrench” icon on the displaypanel and activating an audible alarm. The ventilatorimmediately powers down and opens the internalvalves allowing ambient air to be drawn through theventilator for unimpeded spontaneous breathing. Theaudible and visual alerts remain active and cannot besilenced until the On / Off Switch is placed in theOFF position.

Active: At all times.

6.3.2 Check Ventilator Indicator

Purpose: Alerts the user of a potential abnormal operatingcondition by illuminating the yellow “Eye” icon on thedisplay panel and activating an audible alarm. Theaudible alarm can be temporarily silenced with theALARM SILENCE hard key. However, the visualindicator cannot be reset and remains illuminated untilthe error is corrected. The ventilator continues tooperate during a “Check Ventilator” condition.

Active: At all times.

Purpose

The Exhalation Port Test characterizes the circuit by analyzing the leak rate of the exhalation port. Duringthe test, the system learns the intentional exhalation port leak over the complete pressure range. Thelearned leak value is then stored in system memory and is used to perform leak calculations and provide anaccurate display of patient leak, minute ventilation, and tidal volume in the Data Display Area. When a testis performed successfully, the Data Display shows the unintentional leak. The display will appear as “Pt.Leak” in the Data Display Area. If the test is not performed or cannot be completed successfully, the systemis unable to accurately know the intentional leak and will display the total leak value (intentional + unin-tentional). The display will appear as “Tot. Leak” in the Data Display Area.

NOTE: The Exhalation Port Test should be performed after servicing to ensure the accuracy ofestimated tidal volume and minute ventilation readings. Accurate minute ventilationreadings are necessary to ensure the accuracy of the low minute ventilation alarm whenit is set below 3 L/min.

NOTE: The Exhalation Port Test is recommended before each use, with circuit changes, withchanges in the exhalation port, or after servicing. Completing the test ensures theaccuracy of some displays and alarms.

Equipment Set-up

• First Install a 6’ smooth inner lumen tubing, then a whisper swivel, and then a pressure pick-off port onto the unit outlet.

• Connect a pressure line from the pick-off port to the pressure connection on the Vision unit.

• Occlude the outlet.

Procedure

Step 1 Plug in the power cord. The Main Power indicator will illuminate.

Step 2 Turn the main power switch to the On position and wait for the unit to complete theSYSTEM SELF TEST (internal system check). This will take approximately 5 to 15 seconds.The TEST EXHALATION PORT screen will then be displayed.

Step 8 Wait for the calibration process to complete. The terminal will stop updating information andthe cursor will blink when the process is finished. “Valve Calibration Successful” will bedisplayed. (See below for a description of the Calibration Sequence Summary.)

NOTE: If calibration is unsuccessful, try the test again. If it fails a second time, follow the guidelines on the screen for suggested failure information.

Step 9 Turn the unit Off and remove the power cord.

Step 10 Unplug the test cable from unit unless further testing is required.

Step 11 Remove the test orifice.

Step 12 Install the top enclosure, unless further testing is required.

Step 13 If necessary, carefully position the unit on its side and install the PRV muffler enclosure

Step 14 If necessary, set the unit upright.

Step 15 Test complete.

Calibration Sequence Summary

The first four states are for blower calibration. The blower DAC voltage is increased while the pressure andblower speed are monitored to determine the slope and intercept.

The next two states independently “warm up” the ILFR and PRV valves and then collect four sets ofoperating data on each to use to determine an average value.

All of this information is stored in memory and is used to ensure that the blower and the valves are able tomeet the specified requirements.

BiPAP Vision Oxygen Module Testing for S/N 1007401-108343Note: This test should only be performed once for affected units. If the Oxygen Module has been replaced with a new type, or if your unit does not have a serial number on the oxygen module label, this test does not need to be performed.

Purpose:

1. To perform an additional test on BiPAP Vision units from serial number 107401 to 108343(inclusive). This procedure must be done the first time a Vision that falls within the above listedserial number range is returned for service for any reason. This procedure is to be performedafter the unit passes system final test found in the service manual.

2. This procedure must also be performed on any Oxygen Module repair kit from serial number300000 to 301249 (inclusive) that has been installed into any unit. The serial number is locatedon the cover. Repair parts 582142 and 1004977 are made up of these serial numbers, along withthe production units listed above.

This test will verify the ability of the oxygen delivery subassembly to adequately supply the required flowneeded to yield a specified oxygen concentration at the maximum unit flow rate. Some of these may havehad a vendor assembly problem. Any faults will require the replacement of the Oxygen Module assembly.

Test Equipment:Same as used with oxygen testing found in step K of the System Final Test.

Test Setup:See figure 8-8, except substitute the flow restrictor in the circuit for the test lung. Begin with a small leak.

Procedure:1.) Turn the unit on.2.) After the System Self Test completes, press MONITORING.3.) Press PARAMETERS button and set the following unit parameters:

IPAP = 40 cm H2OEPAP = 20 cm H2ORATE = 10 BPMTIMED INSP. = 3.0 secIPAP RISETIME = .05 secO2% = 21%



1045049

4.) Slowly open the flow restrictor and verify the flowmeter reads a minimum of 130 LPM for fourconsecutive breaths during the IPAP portion of the cycle. If the unit activates the “Disconnect”alarm, it may be necessary to adjust the flow restrictor valve to a lower flow and slowly re-open toreach this flow rate.

5.) Set the O2% parameter to 100% and wait for oxygen analyzer reading to stabilize.

6.) For the unit to pass, the oxygen analyzer reading must remain between 90% and 109% inclusive forfour consecutive breaths. If any unit fails, the Oxygen Module subassembly must be replaced and theunit retested.

7.) When complete, set the unit parameters as follows: IPAP = 15 cm H2O

EPAP = 5 cm H2ORATE = 10 BPMTIMED INSP. = 1.0 secIPAP RISETIME = .05 secO2% = 21%

8.) Press MONITORING button.

9.) Close the oxygen tank valve.

10.) Turn power off and disconnect test equipment.

11.) Test Complete.



1045049

K. Oxygen Module OperationNote: To perform this test it is necessary that the Vision unit being tested have at least 11.8 / 12.4 / 13.4 software. Ifyour Vision unit has earlier software, it is mandatory that it be upgraded before performing this test.

Note: See Figure 8-8 for assistance in connecting oxygen analyzer.

WARNING: Oxygen supports combustion. Do not use oxygen while smoking or in the presence of an openflame.

WARNING: Never use the analyzer to measure gas with a high oxygen content following use on air with an oilvapor content. The oil vapor will contaminate the tubing and may result in a fire on contact withhigh oxygen levels.

Oxygen Module Test Procedure

Step 1Prior to performing this test, a visual inspection should be made of the internal components of theoxygen delivery system including tubing, to ensure that there are no faulty items.

Step 1A Connect the 6 foot smooth inner lumen tubing from the outlet of the Vision, to the Whisper Swivel,then to a pressure pick-off port (O2 port) and then to the TTL Lung (or equivalent). A small length oftubing (approximately 6 inches) may be needed between the pressure pick-off port and the test lung.

Connect the oxygen analyzer cell in the patient circuit.Put the pressure tubing from the pick-off port to the unit’s patient pressure connection.

Or, Using a “T” connector, connect the pressure pick-off port, the unit’s patient pressure connectionand the oxygen analyzer inlet together, whichever applies.

Set the test lung to have a compliance of 0.04 and a parabolic resistance of 20.

Step 2 Turn on the Vision unit.

Step 3 On the unit, press Parameters and set the following unit parameters.

IPAP = 20 cm H2OEPAP = 4 cm H2ORATE = 15 BPMTimed Insp. = 1.0 secIPAP Risetime = .05 secO2% = 21%

1045049

Step 4 Press Monitoring. Ensure that the tidal volume reading on the Vision (Vt) is at 500 ml, +/- 20 ml (480 to520 ml). If not raise or lower the IPAP pressure until the proper tidal volume reading is obtained.

Step 5 Connect the O2 line to the Oxygen Module. Open the O2 cylinder valve. Ensure that the O2 regulatoris set at 50 psi.

Step 6 Wait for the Oxygen Analyzer to stabilize and verify that the reading is 18% to 24%.

Note: Readings should be stable after 8 to 10 breaths. Some variance in the reading may occur,depending on the quality of the analyzer being used.

Step 7 Press Parameters then set % O2 and adjust for 30% O2 level. Wait for the Oxygen Analyzer to stabilizeand verify that the reading is between 27% and 33% (inclusive). If the tidal volume reading on theVision falls out of the acceptable range, adjust the IPAP pressure until the tidal volume falls within theacceptable range before taking the reading.

Step 8 Set the O2 to 100%.

Step 9 Close the O2 cylinder valve. Disconnect the Oxygen hose from the back of the Vision.

Step 10 The unit should alarm for no O2 Flow at 15 Breaths or less.

Step 11 Reconnect the Oxygen hose to the back of the Vision and Open the O2 cylinder valve, set the O2 to40% and press Alarm reset. Verify that no alarms exist after 8 breath cycles.

Step 12 Wait for the Oxygen Analyzer to stabilize and verify that the reading is between 36% and 44%(inclusive). If the tidal volume reading on the Vision falls out of the acceptable range, adjust the IPAPpressure until the tidal volume falls within the acceptable range before taking the reading.

Step 13 Set the unit for 60% O2. Wait for the Oxygen Analyzer to stabilize and verify that the reading isbetween 54% and 66% (inclusive). If the tidal volume reading on the Vision falls out of the acceptablerange, adjust the IPAP pressure until the tidal volume falls within the acceptable range before takingthe reading.



Step 16 Close the O2 cylinder valve. Disconnect the O2 input line.

NOTE: If O2 Module Test Fails, perform the “Oxygen Flow Module Test” found in section 8.11. Then re-run step K above.

1045049

From the repair kit 1004713 or 1000356 (PAV):

1. Locate the EPROMs (version 12) and place them into their respective locations on the MC andPC boards.

2. For non-PAV/T units, remove the original Alarm PAL located in U41 in the MCS and place it inthe new MC board. For PAV/T units, install the PAL provided with upgrade kit 1000356 into U41in the MC board.

3. Remove the DCS from the front panel. Install the DCS EPROM into its respective location.

4. Locate the independent connector supplied with the kit. Insert it into the DCS next to the originalICB connector that is in the center of the board. It should be placed so that the keying (single openslot in the plastic body of the connector) is facing downwards. Solder in place. This will allow forthe new ICB cable to be located so that the ribbon cable is downwards towards the bottom of theunit.

5. Re-install the original DCS back onto the front enclosure.

6. Install the 6-32 nut and one of the aluminum spacers onto the MC board with the spacer locatedon the component side of the board and the nut on the other side. The mounting hole is located bythe power cable connection near the center of the board.

7. Install the MC board into the bottom enclosure. Use the existing nylon “snap” standoffs to beplaced where the original ones were removed, except put the new 8-32 x 3/8 screw in themounting hole with the ground plane around it, which is located along the transformer edge of theMC board.

8. Also for the MC, install new nylon “snap” standoffs in the front left and back left MC mountingholes. Put one of the three nylon standoffs between these two. Put one of the other two nylonstandoffs in the rear behind the power supply connector and the third one opposite of this in thefront of the MC board.

9. Place the original DC ground wire and screw is to put into the mounting hole with the ground planearound it on the front left side of the MC board.

10. Temporarily install the Ribbon cable, 1004699. This is not part of the kit, but should be kept onhand as part of the service tools needed to repair upgraded BiPAP Vision units s/n<106K. It willbe left in only for testing purposes and must be removed afterwards.



1045049

11. Install the PC board onto the MC board standoffs making sure that the power connection near thecenter of the board, and the other similar connector (testing and error data) located in the frontright of the board are fully seated. Also make sure that all of the nylon “snap” locks are fullyengaged.

12. Mount the second aluminum standoff onto the location near the center of the PC board where thefirst aluminum standoff from the MC board can be seen.

13. Connect the blower, valves, circulation fan current sense, Oxygen Module ribbon cable, and thenew ICB cable to the appropriate PC connection points.

14. Locate the new AFM to PC ribbon cable and install it in place. Put this on the PC connection J4to the AFM. The other is connected to J6 for the OM ribbon connection.

15. Connect the new power supply cable to the PSS connection. Note that the new cable has 6inches between the one end connector and the one in the middle. Connect this middle connectorto the power connection on the PC board. Make a counterclockwise loop in the remaining part ofthe cable that will connect to the DCS board. Using the 6-32 x ¼ inch screw and cable clampfrom the kit, attach the power supply cable to the center aluminum standoff in the center of the PCboard. This will allow the cable to be secured, but also allow some movement of the cable duringfront panel removal.

16. Remove the 7 inch piece of pressure tubing that connects from the “T” fitting on the AFM thatoriginally connected to the pressure sensor on the PAS board.

17. Locate the 3 inch piece of pressure tubing in the kit and place one end on the AFM “T” connec-tion and the other end to the redundant pressure sensor. This is the sensor located nearest to theAFM module.

18. Re-install the blower, blower muffler and inlet tubing (if all or any of these were removed). Con-nect the blower connector to the PC board.

19. Re-install the front enclosure, making sure that all the proper connections are secured in place.The patient pressure tubing will go from the front enclosure to the middle pressure sensor, port onthe right side.

20. Make sure all required connections are correctly made. Just a reminder to double check yourwork.

Installation/Upgrade (continued)



1045049

21. When the upgraded unit is first turned on, a Check Vent Error 301 may occur. This will clear afterthe Blower/Valve Calibration is performed on the unit and the unit is cycled off and then on again.

22. Using the Total Operating Hours Transfer found in chapter 8 of the BiPAP Vision service manual,put the original operating hours into the unit.

23. Perform Blower/Valve Calibration found in chapter 8 of the BiPAP Vision service manual.

Note: The PRV muffler DOES NOT get removed once this upgrade is installedinto a unit.

B.1 Schematic StatementSchematics are supplied with this manual in direct support of the sale and purchase of this product.

The schematics are proprietary and confidential. Do not copy the schematics or disclose them to thirdparties beyond the purpose for which they are intended. Patents are pending.

The schematics are intended to satisfy administrative requirements only. They are not intended to be usedfor component level testing and repair. Repairs and testing are supported only at the complete board level.

Respironics does not recommend component repair of the BiPAP Vision. The circuit boards in the BiPAPVision are multilayer boards. Due to the very small trace size, extreme care must be used when replacingcomponents to prevent permanent nonrepairable damage to the circuit board. Components are surfacemounted and require special hot air jet soldering and desoldering equipment. Most of the work should bedone under a microscope set at 25 times magnification. Use of regular soldering equipment will damagethe board and void any applicable warranty.

The schematics are of the revision level in effect at the time that this manual was last revised. Priorrevisions may be obtained upon request.
