5.2.3. CPAP (Continuous Positive Airway Pressure)
In CPAP mode, the ventilator will deliver a continuous flow rate to
generate airway pressure and use the control valve to maintain CPAP
levels (Figure 12).
Note
The default trigger in CPAP mode is pressure trigger (P) which is set at 2
cm H
O below CPAP settings.
2
In this option the ventilator adjusts the amount of flow internally to
maintain average airway pressure close to CPAP setting.
The CPAP mode is equipped with APNEA back up ventilation in which
the ventilator switches to Assist Control ventilation (A/C V) when the
ventilator does not trigger patient's spontaneous breathing for a period
of time (T APNEA) set by the user. The parameters of back up A/C
ventilation are defaulted to volume ventilation based on the initial start
up patient size selection unless changes are made by the user.
The trigger changes from pressure trigger (P) to 3 L/min default flow
trigger when the ventilator switches to APNEA back up.
