6.7.1. E Flow(End of Exhaled flow)
The most important thing in deciding Exhalation time is whether sufficient exhalation has
taken place. If Exhalation time is too short, higher residual pressure called as Self PEEP (or
Auto PEEP) than PEEP pressure remains.
If the flow rate at the end of expiration is zero, then it means that lung pressure is enough
lowered down to PEEP pressure.
It means that the reference lung pressure at the end of exhalation is higher than PEEP. The
cause is short exhalation time.
In mandatory ventilation, if E_flow is not zero, Exhalation time is short and Self PEEP
exists, therefore you must lower the respiratory rate to use it.
On the other hand, if the respiratory rate is increased then you must check that E_flow is
zero after you increase the respiratory rate.
Upper figure : It is sufficient exhalation time and lung pressure is the same as PEEP and
E_flow is zero.
Lower figure : It is insufficient exhalation time and lung pressure is higher than PEEP and
E_flow is not zero.

7.1. Setting Parameter Description
7.1.1. Trigger Function
Trigger sensitivity determines the patient’s effort during breath to induce ventilation from
ventilator.
Trigger sensitivity is configurable with flow trigger(FTRIG) or pressure trigger(PTRIG)
method. In general, flow trigger method can reduce the patient’s effort for breath.
Trigger sensitivity should be configured as high as possible without resulting in self(auto)-
triggering. Such setting increases patient-triggered ventilation and reduces auto-cycling by
the ventilator.
Pressure trigger is configurable within the range of 0.5 ~ 20 cmH2O (pressure trigger
setting is also related to PEEP setting).
Flow trigger refers to the amount of bias flow that must be inhaled by the patient to induce
new breath.
WARNING
The trigger sensitivity bar has different colors based on the setting. A light blue bar
indicates a normal setting for flow. A red bar indicates that triggering is required for flow.
The ventilator continuously delivers a gas flow during expiration, which is measured in the
expiratory channel.
1. Inspiration
Bias flow during expiration is 8 l/min.
WARNING
If the trigger sensitivity is set too high, a self triggering(auto-triggering) condition may be
reached. This condition can also be reached if there is leakage in the breathing system.
Triggering will then be initiated by the system and not by the patient. This should always
be avoided by decreasing the trigger sensitivity.

7.1.2. Inspiratory Rise Time
(Time adjustment from starting point of inspiration to time of peak flow or peak pressure)
The arrival time to peak flow or peak pressure is adjustable to second or percent of
respiratory cycle at the starting point of inspiration for each breath. If rise time is high,
increased flow/pressure and it is displayed through flow and pressure waveforms
Inspiratory rise time is applicable in Pressure Control, PRVC, SIMV-Pressure Control.
Configuration of inspiratory rise time is Fast, Medium and Slow.
In general, configured rise time must be higher than default system value in order to
deliver comfortable ventilation to the patient in support mode.
7.1.3. Respiratory Rate Respiratory rate refers to the number of Respiratory or breaths per minute. The respiratory
rate is also used for calculation of tidal volume if the ventilator is configured for Minute
volume setting.
7.1.4. Apnea Time Apnea time refers to set apnea time until beginning of controlled ventilation in Spont mode.
Range of setting is 2 ~ 60sec.
7.1.5. PEEP Setting range of Positive End Expiratory Pressure (PEEP) is 0 ~ 50cmH2O. PEEP is
maintained in the alveoli and may prevent the collapse of the airways.
7.1.6. I:E Ratio/ Inspiratory Time Inspiratory time setting in MTV1000 ventilator can be done in the following two methods.
- I:E ratio (regardless of change in Respiratory)
- Setting of inspiration time (regardless of change in Respiratory)
Once inspiration time is configured in the ventilator, pause time and inspiratory rise time
are automatically changed. Change in I:E ratio according to inspiration time and pause
time is displayed in information window on the bottom right corner of user interface.
7.1.7. Volume Level Setting During initial setting for each mode of MTV1000 ventilator, volume of air supplied to the
patient can be configured by adjusting inspiratory tidal volume.
MTV1000 Ventilator System 64
User’s Manual
7.1.8. Controlled / Supported Pressure Level In controlled pressure mode, inspiratory pressure (P. INSP) is configurable. Supplementary
pressure (P. SUPP) is configurable in supported Pressure Support, SIMV modes and
tBiLevel.
7.1.9. O2 Cencentration The setting range of O2 concentration is 21 ~ 100%.
There is also an absolute minimum limit of alarm is 18% O2 which is independent of
operating setting. If the value reaches below this point, O2 fail alarm will sound.
The screen only displays O2 concentration of 21% or higher. The alarm is delayed 60
seconds after changing the O2 concentration setting.
7.1.10. Sigh Time It is support a big volume of the patient by providing 1.5times inhalation volume per each
certain breathing in volume mode.
The maximum of volume is 1,500ml.
7.1.11. Proximal Sensor On/Off This option must be used for low flow pressure / flow supplemented patients who require
precise flow measurements and tube compensation such as premature and neonate
patients.
It is safe to use this function in supported ventilation below 200ml.
Appropriate sensor (for adults, for infants) must be used depending on the patient.
7.1.12. Mask On/Off This option can be turned On/Off in all modes except for O2 stream and HFV.
Once turned On, leakage compensation ability is increased.
7.1.13. En_Sense The EnSense means Inhalation-Trigger Enable Sensitivity. It is the function for next
inhalation trigger is triggered only when a certain volume exhalation must be taken place
proportionally to the inhalation volume.
If this function is used, it allows trigger of the patient and can restrict or prevent retrigger
phenomena and mandatory breathing can be successfully maintained.
Before the exhalation volume reach to En_Sense[%] of Vins(Supported Volume), the
trigger(Inhalation Trigger) is not enabled and system be could not go to next Inhalation
Phase by ‘En_Sense’ Function.
In case, Patient has high airway resistance and too much Ascites(Abdominal Dropsy). The
function has another solution to protect retriggering.
7.1.14. Ex_Sense
MTV1000 Ventilator System 65
User’s Manual
The ExSense means Exhalation Trigger sensitivity in pressure mode. The purpose is to
reduce exhalation W.O.B(work of breathing) of patient in pressure support ventilation(PSV).
It reduces patient’s expiring effort compared to the pressure detection mode in the past
and has equipment responses rapidly to the effort of the patient.
Expiration can be taken place only when it exceeds the target pressure after patient
finishes to inhalation. In this case, response speed is late and it needs patient’s effort.
The mechanic characteristic in PSV is not same in each ventilator. The Ex_Sense[%] is to
be decided by individual condition of patients.
If the patient doesn’t have enough spontaneous respiratory capacity, then inhalation must
be sufficiently taken place. Therefore Ex_Sense must be decreased.
7.1.15. Predicted Body Weight It is not the actual body weight and is based on the metabolic rate, and it is used as basic
criteria to determine Respiratory volume per minute, tidal volume, breathing rate, etc., the
trend is on the basis of height than body weight in general.
It becomes the standard of tidal volume multiplied by a BW factor(ml/Kg) and is used to
determine proper Respiratory rate per minute.

Volume control mode is based on mechanical ventilation method and the ventilator
delivers configured tidal volume to the patient.
VACV mode is a mode that controls mechanical ventilation of the patient based on air
volume. It controls inspiratory and expiratory times by force
In Assist/Control mode, Assisted/Controlled Mandatory Breath is provided regardless of

NOTE
Default value is configured in proportion to body weight of the patient.
The airway pressure is dependent on the tidal volume, inspiration time and the resistance
and compliance of the respiratory system. The set tidal volume will always be delivered.
An increase in the resistance and decrease in compliance will lead to an increased airway
pressure. To protect the patient’s lungs from excessive pressure, it is very important to
set the upper pressure limit to a suitable value.
It is possible for the patient to trigger extra breaths if they can overcome the pre-set
trigger sensitivity. It is also possible for the patient, by their own inspiratory efforts, to
receive a higher inspiratory flow and Tidal Volume during an inspiration than pre-set.
During volume control ventilation, peak flow is determined after configuration of tidal
volume and inspiratory time. Also in addition to the above two items, end flow and
plateau are items that influence peak flow.
Volume Control assures a preset tidal volume with constant flow during a preset
inspiratory time at a preset frequency.

7.2.2. V-SIMV(Volume based Synchronized Intermittent Mandatory
Ventilation)
V-SIMV is a mode that controls ventilation based on volume according to spontaneous
ventilation of the patient. In other words, this mode combined control and pressure
support/ spontaneous function allows for preset mandatory breaths synchronized with
the patient’s breathing.
Spontaneous ventilation is done using configured time period or mechanical ventilation is
paralleled based on air volume if there is no spontaneous breathing.
The spontaneous/pressure supported breaths are defined by the setting for Pressure
Support.
WARNING
Mechanical ventilation is paralleled based on volume according to spontaneous ventilation
or in case of no spontaneous ventilation based on time period configured.
SIMV mode is a mode in which Mandatory Breath and Spontaneous Breath are mixed.
SIMV mode guarantees one mandatory breath per SIMV cycle. This mandatory breath is
either patient initiated mandatory (PIM or assisted mandatory) breath or ventilator
initiated mandatory (VIM or controlled mandatory) breath.
As in the figure below, each SIMV breath cycle is divided into two parts. One is
Mandatory Interval (Tm) and another is Spontaneous Interval (Ts). Once PIM breath is
delivered, mandatory interval ends and spontaneous interval (Ts) begins.
If PIM breath does not occur until mandatory interval ends, VIM breath is provided to the
patient as soon as mandatory interval ends and spontaneous interval begins.
MTV1000 Ventilator System 70

This mode controls mechanical ventilation of the patient based on pressure.
When providing pressure control ventilation using mandatory breath in A/C mode,
configure Inspiratory Pressure.
Since pressure is maintained constant during inspiration, flow pattern is in ramp form,
and Plateau function cannot be used.
Since exhalation valve is active exhalation valve, Airway Pressure control becomes more
active and precise. Therefore, increase in pressure caused when the patient talks or
coughs during inspiration can be controlled using exhalation valve. Spontaneous

The delivered volume is dependent upon the pressure above PEEP, lung compliance and
resistance in the patient tube system and airways. This means that the Tidal Volume can
vary.
As the delivered tidal volume can vary it is very important to set alarm limits for Minute
Volume to adequate levels.
When pressure control ventilation is provided by mandatory breath in assist / control
mode, inspiratory pressure is configured. Since pressure is maintained constant during
inspiration, flow pattern is shown in the form of ramp. Plateau function cannot be used.
Pressure Control assures that the preset inspiratory pressure level is maintained
constantly during the entire inspiration.
The preset pressure level is controlled by the ventilator. The resulting volume depends on
the set pressure level, inspiration time and the patient’s lung mechanical properties
during each breath.
Since exhalation valve is active exhalation valve, airway pressure control becomes more
active and precise. Accordingly, exhalation valve is used to control increase in pressure
caused by talking or coughing of the patient during inspiration. It also allows the patient
to spontaneously breathe.
If the pressure increases to the set upper pressure limit, the expiratory valve opens and
the ventilator switches to expiration.

7.2.5. PRVC(Pressure Regulated Volume Control Ventilation)
Pressure Regulated Volume Control (PRVC) is a mechanical ventilation mode based on auto
pressure control. Constant volume is maintained through target volume and pressure limit
setting.
The ventilator delivers a pre-set Tidal Volume. The pressure is automatically regulated to
deliver the pre-set volume but limited to 1 cmH2O below the set pressure limit.
PRVC assures a set target minute ventilation to the patient. The target volume is based
upon settings for Tidal Volume, frequency and inspiration time.
The inspiratory pressure level is constant during each breath, but automatically adapts in
small increments breath-by-breath to match the patient’s lung mechanical properties for
target volume delivery.
Despite advantages of pressure mode, instability of not guaranteeing inspiratory volume,
caused by long-term or acute change in patient’s respiratory status or long-term change in
lung compliance, is removed.
The ventilator delivers configured tidal volume. Pressure maintained for supply of
configured tidal volume is automatically adjusted within the range of pressure limit.
The first breath of a start sequence is a volume-controlled test breath with pressure of
16cmH2O. The measured pause pressure of this breath is then used as the pressure level
for the following breath.

7.6.3. EtCO2 Monitoring
EtCO2 sensor displays CO2 concentration of the patient towards the end of inspiration as
a graph.
The IRMA CO2 main stream CO2 probe is intended to be connected to other medical
devices for display of real time and derived monitoring data of CO2.
It is intended to be connected to a patient breathing circuit for monitoring of
inspired/expired gases during anesthesia, recovery and respiratory care. It may be used
in the operating suite, intensive care unit, patient room and emergency medicine
settings for adult, pediatric and infant patients.
It shall always be used in combination with other vital signs monitoring devices and/or
professional human judgments of patient condition. The IRMA probe is intended to be
used by trained and authorized health care professionals only.
Stage Description
1 ~ 2 Initial stage of expiration in which gas inside anatomical dead space with almost no
carbon gas is discharged
2 ~ 3 Stage in which gas from pulmonary alveoli and gas inside anatomical dead space are
mixed and discharged
3 ~ 4 Stage in which gas from pulmonary alveoli is discharged
4 Partial pressure (concentration) of carbon dioxide towards the end of expiration
4 ~ 1 Inspiration
1) Setup Connection
A. Connect the IRMA analyzer interface cable to the “Gas Extension cable”.
Snap the IRMA probe on top of a new IRMA airway adapter. It will click into
place when properly seated.

B. A green LED indicates that the IRMA probe is ready for use.
C. Connect IRMA/airway adapter 15 mm male connector to the breathing circuit Y-
piece.
D. Connect the IRMA/airway adapter 15 mm female connector to the patient’s
endotracheal tube.
Alternatively, connect an HME (Heat Moisture Exchanger) between the patient’s
endotracheal tube and the IRMA probe. Placing an HME in front of the IRMA
probe protects the airway adapter from secretions and effects of water vapor
and eliminates the need of changing the adapter. It allows free positioning of
the IRMA probe as well.
Unless the IRMA probe is protected with an HME always position the IRMA
probe with the status LED pointing upwards.

E. Placement of IRMA Probe
I. When connecting IRMA probe to an infant patient circuit it is important to
avoid a direct contact between the IRMA probe and the infant's body.
II. If, for whatever the reason, the IRMA probe is in direct contact with any
parts of the infant's body an insulation material shall be placed between the
IRMA probe and the body.
WARNING
▣ The IRMA probe is intended for use by authorized and trained medical personnel only.
▣ The IRMA probe must not be used with flammable anesthetic agents.
▣ Disposable IRMA airway adapters shall not be reused. Reuse of the single use adapter
can cause cross infection.
▣ Used airway adapters shall be disposed of in accordance with local regulations for
medical waste.
▣ Do not use the IRMA Adult/Pediatric airway adapter with infants as the adapter adds 6
ml dead space to the patient circuit.
▣ Do not use the IRMA Infant airway adapter with adults as this may cause excessive
flow resistance.
▣ Measurements can be affected by mobile and RF communications equipment. It should
be assured that the IRMA probe is used in the electromagnetic environment specified
in this manual.
▣ Do not place the IRMA airway adapter between the endotracheal tube and an elbow as
this may allow patient secretions to block the adapter windows and result in incorrect
operation.
▣ Do not use the IRMA airway adapter with metered dose inhalers or nebulized
medications as this may affect the light transmission of the airway adapter windows.
▣ The IRMA probe is intended only as an adjunct in patient assessment. It must be used
in conjunction with other assessments of clinical signs and symptoms.
▣ Incorrect probe zeroing will result in false gas readings.
▣ Replace the adapter if rainout/condensation occurs inside the airway adapter.
▣ Use only PHASEIN manufactured IRMA airway adapters.
▣ The IRMA probe is not intended to be in patient contact.
▣ Only use CO2 components certified by MEKICS.
CAUTION
▣ Never sterilize or immerse the IRMA probe in liquid.
▣ Do not apply tension to the probe cable.
▣ Do not operate the IRMA probe outside the specified operating temperature
environment.
▣ Federal law restricts this device to sale by or on the order of a physician. (U.S.)
▣ The IRMA Airway Adapters are non-sterile devices. Do not autoclave the adapters as
this will damage them.
