NOTE

The ventilator does not generate subatmospheric airway pressure during exhalation.

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 cmH2O
（
adjustable pressure limit
）
, the ventilator
opens the safety valve to release pressure, so that the airway pressure

falls to 3 cmH2O for continuous 0.5 s. Make sure to set high pressure alarm limit properly
to ensure patient safety.

The PC-ACV and PC- SIMV mode, VT
＞50ml,
are the recommended ventilation modes and
TV tidal volume for use with a closed-suction catheter. And the settings are decided by the
operator according to the patient situation.
