Auto-EPAP
Auto-EPAP's main purpose is to maintain upper-airway patency (within prescribed
EPAP limits). All other EPAP functions remain the responsibility of the clinician. When
Auto-EPAP is active it remains the responsibility of the clinician to ensure that the mini-
mum and maximum EPAP limits are configured so that any other EPAP objectives are
satisfied.
Auto-EPAP is paused during ramp up/down if activated.
Function
With Auto-EPAP, the ventilator will adjust the EPAP within preset limits in response to
detection of obstructive Apnea and obstructive Hypopnea events to prevent further
occurrence of such events.
