To Perform an AutoPEEP Maneuver

The AutoPEEP maneuver allows the measurement of PEEP generated within the breathing system (patient and circuit)
during an expiratory hold maneuver. This maneuver requires a passive patient.
From the Maneuvers Screen select AutoPEEP
The AutoPEEP maneuver screen allows the operator to set:
Sensitivity – This sets the sensitivity threshold that the ventilator uses to detect patient effort during the AutoPEEP
Maneuver. The default position is 3 cmH
applications.
Start / Stop – Starts and Stops the maneuver.
To execute an AutoPEEP maneuver the operator sets the Sensitivity appropriate for the patient and presses the Start
softkey. The ventilator will then close the inspiratory and expiratory valves and allow the pressure to equilibrate between
the patient and the breathing circuit. At the completion of the maneuver the ventilator will display the AutoPEEP and
dAutoPEEP values in their respective windows on the maneuver screen. The AutoPEEP and dAutoPEEP will also be
available as trended data on the Trends screen. The maneuver can be aborted at anytime by pressing the Stop soft key.
Note:
The AutoPEEP value will be set at the next mandatory breath interval or 5 seconds whichever is sooner.
Chapter 4: Monitors, Displays and Maneuvers
The preset Sensitivity establishes the level that the airway pressure must drop below PEEP to
abort the AutoPEEP maneuver.
