The following list contains all warning, caution and advisory alarms
associated with breathing pressure monitoring.
If the measured breathing pressure remains below the threshold
pressure alarm limit for more than 15 seconds, the Caution message
APNEA-PRES appears on the central alarm display and an intermittent
audible alarm sounds.
If the breathing pressure remains below the threshold pressure for an
additional 15 seconds (30 seconds total), the Caution message APNEA-
PRES is upgraded to a Warning on the central alarm display. During
the Warning condition, the breathing pressure display area is cleared
and a continuously repeating audible alarm sounds.
If the measured breathing pressure exceeds the high pressure limit, the
Warning message VENT PRES HI appears on the central alarm display
and a continuously repeating audible alarm sounds.
This alarm condition is cleared when the measured breathing pressure
drops below the high pressure alarm limit. However, the alarm message
is extended for 5 seconds to allow for recognition of a momentary high
pressure condition.
If the measured breathing pressure falls below -10 cmH
message SUB ATM PRES appears on the central alarm display and a
continuously repeating audible alarm sounds.
This alarm condition is cleared when the sensed pressure rises above
-10 cmH O. However, the alarm message is extended for 5 seconds to
2
allow for recognition of a momentary subatmospheric pressure condition.
If the measured breathing pressure remains above the threshold
pressure alarm limit for more than 15 seconds, the breathing pressure
display area is cleared, the Caution message CONTNG PRES appears on
the central alarm display, and an intermittent audible alarm sounds.
When the measured breathing pressure drops below the threshold pres-
sure alarm limit, alarm annunciation ceases.
