Power off when the equipment is not fully installed. Otherwise, the equipment could be damaged.



Caution

Classification of BT-750 :

- BT-750’s class is “Class IIb” equipment.

- It is type “CF grade” for ECG, Resp, IBP and “BF grade: for

EtCO2, SpO2, NIBP and Temp.

- The noise level is“ B” Class according to the IEC/EN 60601-1

(Safety of Electric Medical Product), and the noise redemption is

“B” Level according to the IEC/EN 60601-1-2 (Electromagnetic

Compatibility Requirements)

- Protection grade against water is“ IPX 0”

- Do not use this product around a flammable anesthetic and solvent.

Caution

Although BT-750 has been value of measurement in compliance

with existing EMI/EMC requirements, use of this system in the

presence of an electromagnetic field can cause momentary

degradation of the SpO2 waveform. If this occurs often, Bistos

suggests a review of the environment in which the system is being used, to

identify possible sources of electromagnetic waves. These waves could be

from other electrical devices used within the same room or an adjacent

room. Communication devices such as cellular phones and pagers can

cause these waves. The existence of radio, TV or microwave transmission

equipment located nearby can cause electromagnetic waves. If EMI causes

disturbances, it may be necessary to relocate your system.

Electrostatic discharge (ESD), commonly referred to as a static

shock, is a naturally occurring phenomenon. ESD is the most

prevalent during conditions of low humidity, which can be caused by

heating or air conditioning. During low humidity conditions,

electrical charges naturally build up on individuals and can create

static shocks. An ESD condition occurs when an individual with an

electrical energy build-up comes in contact with objects such as

metal door knobs, file cabinets, computer equipment, and even other

individuals. The static shock or ESD is a discharge of the electrical

energy build-up from a charged individual to a lesser or non-charged

individual or object. The level of electrical energy discharged from a

system user or patient to the BT-750 can be significant enough to

cause damage to the system or probes. The following precautions can

help to reduce ESD: anti-static spray on carpets; anti-static spray on

linoleum; anti-static mats.

Measurement of SpO2

7.1 Preparation for SpO2 Measurement

1) Connect SpO2 probe to the probe port.

7.1.1 Setting SpO2 Probe

1) Clean the body part (a finger or a toe) to be inserted to probe for measurement with

alcohol.

2) Set the probe on the finger to measure. (Avoid using it with other medical devices to

affect blood flow and setting it on the body part in medical treatment )

3) Do not make any motion and be in pause as possible as you can for stable measurement

and fix the probe cable with your fingers or plasters but be careful not to make interference in

blood flow.

SpO2 Connector



4) Make sure that the probe is set on the body part correctly in every 2 or 3 hours. If the state

of your skin is different, change the part to be attached to other side.

Note

When probe is used incorrectly, inaccurate value or waveform can

come out as below.

● When the patient uses the probes without certification of Bistos

Technology.

● Hemoglobin dysfunction

Caution

Probe should be treated with attention. Careless use might cause

damage to probe. Keep the probe cable away from acute objects.

When the patient has a high fever or peripheral circulatory failure,

the skin, temperature increases to 2~3 degree.

In case of the patients with cold fingers, SpO2 data is not accurate.

For the patients who have abnormally high oxyhemoglobin or

methemoglobin , SpO2 data is not accurate.

You can not use disposable probe to different patients. For same

patient, it is possible to reuse and remeasure even in different

portion. If you want to reuse disposable probe, disinfection is

indispensable.

Caution

It might fail to measure pulse rate under occasions as follows;

When probe is fastened tightly.

When probe excessively exposes to Medical illumination, bilirubin

illumination or sunlight.

In case of being measured on arms or legs in cuffs or bandages.

Warning

In case of measuring with probe while MRI is in use, the patient may

have burns. To minimize the danger, use non-inductive line, if there

exists any danger even with proper use, remove the connector from

the patient.

● Allergic patients should not use disposable probes.

● Make sure that the probes radiate light, faced each other correctly,

and the light reaches to the tissue of a patient. When applying to a

newborn baby, use disposable probes outside of the incubator.

● If used in an incubator, accurate results may not be obtained

because the humid air can have an effect on the outcome.

When probe is excessively fixed with tape or used in other incorrect

way, the patient may suffer from injury.

Warning

If the probe are excessively exposed to medical illumination

( especially for xenon light ), bilirubin illumination, fluorescent

lamp, IR heating appliances or direct ray of light , this may cause

problem in function . To avoid excessive exposure to the light, use it

by the general operation and be careful that the probe is not exposed

to outside ray with opacity. If outdoor circumstance is under

extremely high light, it may generate inaccurate value.

Do not use probe at the body part where intravenous injection or

artery catheters are placed.

Do not use damaged SpO2 probe or optical appliances.

Do not clean with oxygenated water, ultraviolet ray, direct ray of

light and steam.



Chapter 8

Measurement of NIBP

8.1 Setting NIBP

1) Choose the proper cuff for the patient.

2) Connect the cuff hose to cuff.

3) Connect the cuff hose to NIBP font.

4) Put the cuff on the patient.

5) Use the proper cuff to the patient before measuring blood pressure.

8.1.1 NIBP measurement

1) It should be measured at the same label of the patient’s heart in the arms and legs of the

patient.

2) The cuff ties part under the position to be measured.

It may cause errors in measurement values.

3) NIBP measurement will be done with button

and if you press the button one more time, it

stops measurement.

Note

It is impossible to measure the blood pressure in upper arm, in case

that infusion pump or catheter is inserted in the blood vessel. It may

cause damages in the organ around catheter during the supply of

blood pressure.

Caution

Use the proper cuff to the patient before measuring blood pressure.

Inspect excess blood pressure or folding of cuff.

Avoid the cuff from getting wetness out of any kinds of incidents,

and use it after dry completely.

Chapter 9

Measurement of Temperature

9.1 Temperature Measurement

● Changes in impedance according to the change in the patient’s body temperature is

perceived by the temperature sensor, and then displayed numerically on the screen after a

series of calculations. Measured Temp

1) Connect the temperature sensor to the connection terminal of the measurement module

and sensor to patient.

Caution

The temperature sensor should be sterilized before application to

another patient.

Temperature Connector



Chapter 10

Measurement of IBP

10.1 IBP Measurement

Arterial Blood Pressure is the pressure exerted by the blood against the walls of the arterial

vessels. The cardiac cycle consists of a period of relaxation called Diastole, during which

the heart fills with blood, followed by a period of contraction called Systole. While the heart

is contracting and relaxing, the sensor gets the measurement of the pressure.

10.2 Setup Connections 1) Connect the interface cable for the transducer to the IBP connector on the monitor’s front

panel. An interface cable for the transducer has to be selected correctly as it depends on

the each transducer type.

Note

The monitor is designed to accept signals from BT4812-3 disposable

transducer, or equivalent (pressure range of 0~300 mmHg). Refer to

the transducer directions for use for details.

*This transducer is verified under the connection with to see if

protective means is provided against hazards to patient when used

with HF surgical equipment.

IBP Connector



2) Set up the patient circuit according to the directions for use of the transducer, monitoring kit.

3) “Hold the backside of the clear cover surrounding the connector, and connect the converter

to the reusable monitor interface.

4) In a clean environment, open the package to check if all parts are well connected and if the

handle of the “stopcock” is positioned properly. All side ports of the stopcock are protected

by the outlet plugs and may not be removed till the system is full and the foam has been

removed. These outlet plugs should always be replaced with other outlet plugs. (A pouch is

included in the kit.).



5) How to use Flush

Hold both sides of the flush operator and pull upward gently. Do not revolve the operator and

take care not to put the power on one side.

Caution

If a fast flush is performed on the patient, the user should check

carefully for the presence of foam and particulate matter. If a large

volume is flushed by force, a short flush with an increase rate less

than 2cc is recommended to avoid central embolism.

Blood pressure for a liquid infusion line over 300mmHg requires an

infusion of more than 3cc per hour. In this case, the pressure must

not exceed 775mmHg. A protective function is set in the flush

device, which prevents overpressure of the converter by making the

liquid bypass the device. If a more precise control of fluid volume is

required, it is necessary to connect the infusion pump around the

flush device.

6-1) Twist the sterilized solution bag lightly using a drip chamber spike

6-2) Open the roller clamp and remove the air inside the bag completely by squeezing

using an infusion set or a needle inserted into the injection port in the back. By emptying

the back this way, it can prevent air input into the patient’s body.

6-3) Before inputting the solution into the infusion set, push both sides and fill the drip

chamber partially.

6-4) Operate the flush device gently. Since air rises from the bottom, make sure that the

solution is in the bottom at all times.

6-5) Prime the side ports and the plug of the zero point stopcock in the converter using a

door-lock plug.

6-6) Check if bubbles are present in the monitoring system. To check the presence of

invisible bubbles, rap it lightly

6-7) Add pressure to the system up to 300mmHg using C-fuse or the clear cuff. Flush the

system for 2~3 seconds. Check for the presence of air bubbles which may result from a fast

flush. Now, the system is ready for zero point setting and measuring. Place the stopcock in

a 90 degree position to let it off state.



Caution

The stopcocks of the converter or the outlet should be locked before

connecting the door-lock plug.

Note

>

● Priming should be done slowly!

- Slow priming will lessen the effort to remove air bubbles afterward.

● Priming using gravity!

- Pressing may result in leakage of liquid or bubbles by forcing the

liquid to flow into the system. If small bubbles flow too slowly

inside the system, lift up the supply bag. 1 inch corresponds to

2mmHg, and the primed 4-feet line gives a pressure of about

100mmHg if it is completely spread out The solution bag should

be placed at a higher position than the converter and the pressing tube,

in order for priming using gravity.

Caution

If air foam or bubbles are present inside the system, it may cause

significant bias of the pressure waveform or air embolism.

Care should be taken not to let air bubbles inside the 3-way outlet

stopcock or the cannula reflush into the patient. To check, confirm if

the monitoring line is fully filled with liquid before connecting the

monitoring line and let a small volume of blood flow through the

cannula.

10.3 Adjustment of Zero point of the Converter

1) Lock the zero point stopcock (toward OFF) and release the converter according to the air

pressure.

2) Set “Menu”-> “Zero”-> “Yes” in order. If final value is “0”, the measurement starts.

Sidestream CO2 Gas Measurement

Sidestream CO2 module can be fitted onto BT-750. Sidestream CO2 provides the function of

ETCO2 and the function to measure respiratory CO2 and respiration numbers using the small

filterline based on a small lumen type filterline. In the Sidestream CO2 type, the level is

measured through the cannula (non-tubing type) attached to the nose or a sampling line

equipped in the respiratory circuit (tubing type).

Caution

The maximum sampling rate of the nose tube is 50mL/min. The

product should not applied to patients who may experience

respiratory distress by the vacuum flow level.

To prevent infection of the medical staff by the patient’s respiration

sample, the outlet of BT-750 should be connected to the air

elimination system of the hospital.

Caution

The gas inspiring vacuum pressure (negative pressure) of the gas

elimination system should not exceed the pump outlet standard of

BT-750, 1mmHg. Excessive pressure will display the message of

“OCCLUSION” and it may damage the BT-750 product pump.

During zeroing, the air elimination system should be operating.

Waste from Microstream and CO2 filter should be treated as fatal

biological materials for the human body

Note

Connection of all tubes should be safe, and the nose cannula should

be kept away from the CO2-present area during the self test period

(including the outlet of the ventilator and the respiration of the user).

Range of Respiration Measuring : 0 ~ 150bpm

For the best accuracy, a warm-up of about 2 minutes is required.

Note

We do not use specific gas for calibration and manually operate “O”

Calibration.

When you adjust “O” calibration, connect it to the transducer and

monitor in the air. The patient may not connect it to the other gas.

Operate “ Menu → ZERO → YES” in order .

Use it after verifying “O” value at the window screen, otherwise the

measurement value would not be correct.



11.2 How to measure Sidestream CO2

1) Attach the gas/tube to BT-750 Sidestream port and the other side attach to hospital gas

device

2) Respiration numeric is automatically changed when EtCO2 is measured.

3) EtCO2 will be displayed on BT-750 screen after 20 seconds when it detect proper input.

4) EtCO2 waveform and data is displayed. If waveform is not displayed on the screen, change

setting menu “Menu → EtCO2 → EtCO2 → Enable

5) You can change EtCO2 waveform when you need.

Caution

The watertrap is disposable and should only be used for a single

patient. Do not reuse the watertrap for another patient.

Caution

The cannula is disposable and should only be used for a single

patient. Do not reuse the cannula for another patient.

Caution

If oxygen is being delivered while using Sidestream CO2, be sure to

use a CO2 Sampling and O2 Delivery cannula. Using a different type

of cannula could obstruct oxygen delivery.

Warning

Assembly, extension, repair should be carried out by authorized

person from Bistos Technology.

Caution

When harmful (unaccepted) materials are used for cleaning, we shall not

offer the service without charge in regardless of warranty period.

Check carefully both monitor and probe after cleaning the equipment.

Do not use the equipment that is worn out or damaged.

Caution

You can get incorrect measurement figure under the following conditions.

- The patients’ excessive motion

- Using electrical operational instrument with high-frequency or the

instrument for cardioversion.

- Venous blood pulse

- Appling to the monitor parts to measure blood pressure or use arterial

catheter/bandage and intravascular parts

- When the patients are on low blood pressure, severe blood vessel

contract, sever anemia or low body temperature.

- Arterial occlusion nearby probes

- When the patients are on cardiac arrest or shock.

Premature neonates and patients with chronic pulmonary disease should be checked for oxygenation levels before starting treatment.

To prevent electric noise during use, the product should be installed apart from dynamo, X-ray equipment, broadcast equipment or portable

cables. An inaccurate result may occur when these equipment are placed

near the product.

To ensure patient is electrically isolated, connect only to other

equipment that provides patient electrical isolation. When the patient

with pacemaker use the monitor, only qualified personnel should

operate and control all functions of the monitor.
