5.6 The EXP PAUSE and INSP PAUSE keys (760 only)
You can use the EXP PAUSE key to calculate
the patient’s auto-PEEP (an estimate of the
pressure that remains in the patient’s lungs
at the end of exhalation, also known as
intrinsic PEEP or occult PEEP). The presence
of end expiratory flow (displayed as
E: End xx in the message window) indicates
the presence of auto-PEEP.

1. Press the EXP PAUSE key during inspiration or exhalation: The
key lights, and the ventilator closes the exhalation valve at the
end of the expiratory phase without delivering a breath.
Until the maneuver begins, the ventilator displays this message:
Exp pause requested
During the maneuver the ventilator displays this message:
Exp pause active
2. The EXP PAUSE maneuver ends when you release the key: hold
the key down only until expiratory pressure stabilizes (watch
the pressure bar graph or the message window).
3. Once you release the EXP PAUSE key, the message window
continues to display the patient’s calculated auto-PEEP for
30 seconds:
PEEP: i=xxx t=xxx
where i is intrinsic PEEP and t is the total PEEP
(total PEEP = measured PEEP + intrinsic PEEP).
Once the maneuver is complete, the ventilator immediately
delivers the mandatory breath that was suspended for the
maneuver.
