Ventilation modes
78
CPAP mode
CPAP mode delivers a constant level of pressure during inspiration and expiration.
With CPAP administered via a valved breathing system, the inspiratory triggering level is settable to
optimise the control of the exhalation valve and minimise the patient's work of breathing. Adjust trigger
sensitivity to accurately report patient respiratory rate.
In a vented system, the inspiratory triggering level is settable to optimise monitoring and alarm
performance.
