PEEP > 25

THRESHOLD LO
(Advisory)
PEEP > 4
(Advisory)
APNEA-P OFF
(Advisory)

Problem Resolution

Any time that the monitor measures a PEEP of 26 cmH
the Caution message PEEP > 25 appears on the central alarm display
and an intermittent audible alarm sounds.
Alarm annunciation ceases when the measured PEEP drops below
26 cmH O. Also, an APNEA or CONTINUING PRESSURE alarm condition
2
will clear this alarm condition.
The Advisory message THRESHOLD LO appears on the central alarm
display any time the sensed peak pressure exceeds the threshold
pressure alarm limit by more than 6 cmH
limit settings of 5–20 cmH
pressure alarm limit settings of 21–29 cmH
pressure alarm limit at 30 cmH
advisory.
Any time the monitor measures a PEEP of 5 cmH
Advisory message PEEP > 4 appears on the central alarm display.
When the measured PEEP drops below 5 cmH
is cleared from the display.
Any time that the apnea pressure alarm (threshold pressure alarm limit)
has been disabled, the Advisory message APNEA-P OFF appears on the
central alarm display. This Advisory is also generated automatically
after power-up if the ventilator power switch is in the OFF position.
