Cause
The pressure switch that
detects flush flow has seen a
very long flush (≥30
seconds).
Ventilator malfunction.
The mains supply is not
connected or has failed and
the system is using battery
power.
Exhaled volume <50% of
inspired volume for at least
30 seconds (mechanical
ventilation).
Subatmospheric pressure
(<-10 cmH
O).
2
Pmin does not reach within
± 2 cmH
O of PEEP by the

end of mechanical
expiration for 6 consecutive
breaths.
Ventilator malfunction.
Manifold pressure not
tracking airway pressure, or
manifold pressure
≤ -15 cmH
O.

Outlet selection switch is set
to auxiliary gas outlet.
Action/Concerns
This alarm occurs if you hold
down the Flush button for more
than 30 seconds.
Ventilate manually.
Ventilate manually to save
power. At full charge, the battery
permits approx. 30 minutes of
mechanical ventilation.
Check breathing circuit and flow
sensor connections.
Check patient condition,
spontaneous activity? Increase
fresh gas flow. Look for high flow
through gas scavenging.
Check tubing connections. Rate
and/or I:E ratio may prevent
ventilator from reaching desired
PEEP level.
Ventilate manually. Monitoring is
not reliable.
Pressure control mode and PEEP
are not available. Switch to
Volume mode or ventilate
manually.
Check patient for spontaneous
breathing.
Check ventilator settings.
Connect the patient circuit to the
auxiliary gas outlet or set the
switch to the circle breathing
system.
Repair
If the alarm occurs
when flush is not in
use, contact a qualified
service representative.
Contact a qualified
service representative.
Make sure power is
connected and circuit
breakers are closed.

Calibrate the flow
sensors.
b
With active
scavenging, check the
negative relief valve on
the receiver.
