3.7 Install the Nebulizer
NOTE
Install the specified nebulizer. The nebulizer assembly and its installation steps
described in this section are only for reference. Refer to the nebulizer
accompanying directions for use to install and use the nebulizer.
To prevent the expiration valve from sticking due to nebulized medications, use
only medications approved for nebulization, and regularly check and clean or
replace the expiration valve membrane.
Do not use an expiratory filter or HME in the patient’s breathing circuit during
nebulization. Nebulization can cause an expiratory side filter to clog, substantially
increasing flow resistance and impairing ventilation.
Connect the nebulizer to the inspiratory limb. Connecting the nebulizer between
the patient connector and the endotracheal tube increases dead space ventilation.

6-6
WARNING
Incorrect tube type, ID or compensate setting can endanger the patient. Make sure
to set them properly.
CAUTION
Do not attempt to use NIV on intubated patients.
6.5.2 Non-Invasive Ventilation (NIV)
NIV means to ventilate the patient by using a nasal mask or facial mask instead of ET tube or
Trach tube. In NIV, the enabled ventilation modes include:
Adult and pediatric patients: CPAP/PSV, P-A/C and PSV-S/T ventilation modes.
Neonate: P-A/C, PSV, nCPAP and PSV-S/T ventilation modes.
CAUTION
Do not use NIV on patients with no or irregular spontaneous breaths. NIV is
intended to provide supplemental ventilatory support to patients with regular
spontaneous breaths.
Do not attempt to use NIV on intubated patients.

6.6 Ventilation Mode
NOTE
At the expiratory phase, the ventilator will not automatically generate negative
pressure. However, it may cause negative pressure because patients inhale air.
The user can set high pressure alarm limit. If the pressure reaches the high pressure
alarm limit in the inspiratory phase, the [Paw Too High] high-level alarm is
triggered. The ventilator opens the expiration valve and switches to expiratory
phase until the airway pressure reaches the preset PEEP value. If the airway
pressure exceeds high pressure alarm limit+5 cmH
the ventilator opens the safety valve to release pressure, so that the airway pressure
falls to less than 3 cmH
alarm limit properly to ensure patient safety.
As false triggering of the ventilator can easily be caused by negative pressure
produced during closed suction, it is recommended that the pressure-controlled
ventilation mode (P-A/C mode or P-SIMV mode), in which ventilation trigger can
be turned off, be used first. The operator should complete ventilation parameter
settings in accordance with the patient's condition.

6.6.2 V-A/C
V-A/C is volume-assist/control ventilation mode. In V-A/C mode, a certain tidal volume is
delivered to the patient within a certain period of gas delivery time. During the expiratory
phase, V-A/C mode supports synchronization trigger. Namely, when the ventilator detects
patient inspiratory effort, it delivers next mechanical ventilation in advance.

6.6.3 P-A/C
P-A/C is pressure-assist/control ventilation mode. In P-A/C, the patient’s airway pressure
rises to the preset pressure level within the time of pressure rising during the inspiration
phase, and is held at this level till inspiration time is completed. Then the system switches to
expiration. When the airway pressure is held at the preset pressure level, delivered gas flow
has decelerating shape, and varies with the resistance and compliance of the patient’s lungs.
During the inspiratory phase, when the volume of gas delivered exceeds the tidal volume
high alarm limit, the system switches to the expiratory phase immediately. During the
expiratory phase, synchronization trigger is supported. Namely, when the ventilator detects
patient inspiratory effort, it delivers next mechanical ventilation breath immediately.

6.6.4 V-SIMV
V-SIMV is volume-synchronized intermittent mandatory ventilation mode. It provides the
minimum number of mandatory breaths based on the preset intermittent mandatory
ventilation frequency. Mandatory ventilation mode is volume mode (V-A/C mode). If patient
triggers within the trigger window, ventilator delivers mandatory volume control breath once.
Mandatory volume control breath is also delivered once if it is not triggered at the end of
trigger window. Spontaneous breathing or pressure support breathing is supported outside the
trigger window. The duration of trigger window is 5s for adults and 1.5s for pediatrics and
neonates. If the expiratory time is less than the duration of trigger window, the trigger
window covers the expiratory time. The following figure shows typical waveforms in

ventilation frequency. Mandatory ventilation mode is pressure mode (P-A/C mode). If patient
triggers within the trigger window, ventilator delivers mandatory pressure control breath once.
Mandatory pressure control breath is also delivered once if it is not triggered at the end of
trigger window. Spontaneous breathing or pressure support breathing is supported outside the
trigger window. The duration of trigger window is 5s for adults and 1.5s for pediatrics and
neonates. If the expiratory time is less than the duration of trigger window, the trigger
window covers the expiratory time. The following figure shows typical waveforms in

6.6.6 CPAP/PSV
PSV is pressure support ventilation mode. The system delivers a PSV when it detects that
patient inspiratory effort reaches the preset inspiration trigger level. Time of pressure rising
and pressure support level are set by the user. At the beginning of inspiratory phase, the
patient’s airway pressure rises to the preset pressure level within the preset time of pressure
rising, and is held at this pressure level till patient inspiratory flow is detected to reach the
expiration trigger level. In PSV, when the airway pressure is held at the preset pressure level,
delivered gas flow decelerates, and varies with the resistance and compliance of the patient’s
lungs.
