6.7 Ventilation Mode
NOTE
The ventilator creates negative pressure in the expiratory phase due to patient’s
active inspiration. There is no limit pressure for negative pressure in the expiratory
phase. Instant negative pressure is caused by patient’s active inspiration. In the
inspiratory phase, high pressure alarm limit is available. When high pressure
alarm limit is reached, the ventilator releases pressure immediately. Pressure in the
inspiratory phase is generated by the ventilator gas delivery.
The P-A/C and P-SIMV are the recommended ventilation modes for use with a
closed-suction catheter. And the settings are decided by the operator according to
the patient situation.
