EXP PAUSE
(760 only)
Allows you to measure the patient’s auto-PEEP. An EXP PAUSE
maneuver causes the ventilator to close the exhalation valve
at the end of the expiratory phase, and not deliver the next
mandatory breath. At the end of the maneuver, the message
window shows the calculated value for auto-PEEP (expiratory
pressure at the beginning of the maneuver minus expiratory
pressure at the end of the maneuver) and total PEEP for
30 seconds.
The message window shows the end expiratory flow in L/min
at the beginning of each breath. If there is expiratory flow
when the ventilator delivers the next breath, auto-PEEP is
present.
The EXP PAUSE continues as long as you hold down the key,
and should last only until expiratory pressure stabilizes. An
EXP PAUSE maneuver ends when you release the key, the
patient initiates a breath, an alarm occurs, the expiratory
phase (including the maneuver) lasts more than 20 seconds,
or the ventilator detects a leak.
Auto-PEEP:
Range: 1 to 35 cmH 2 O.
Accuracy: ± (1 cmH 2O + 3% of reading).
The EXP PAUSE maneuver is unavailable when the
RESPIRATORY RATE setting is less than 3 /minute.
