Water accumulating in the
breathing circuit
Gas is cooling as it travels through
the circuit tubing.
Keep tubing as short and warm as possible between the
humidifier and the airway so that water remains in the
vapor state.
Keep tubing away from cold surfaces.
Do not aim a cooling fan at the tubing.
If appropriate, use a heated wire circuit.
Water trap needs to be emptied.
Empty the water trap frequently.
Audible alarm is too quiet
Alarm loudness is set too low.

Power
P
ac battery does not last
long enough
Not fully recharged.
Connect the Power Pac to external AC or DC power for
at least 3 hours between uses.
Ventilator settings/patient
condition (a large leak during
pressure ventilation, a high level of
bias flow setting, or an aggressively
breathing patient) demand more
gas delivery than the standard
settings.
The Power Pac battery is functioning normally. Carry at
least one extra fully charged Power Pac battery (part
number BAT3271A) for ventilator dependent patients
and for patients whose ventilation pattern requires
higher battery power consumption.
Power
P
ac needs to be replaced.
Contact Covidien Technical Services for assistance.
Reference
Check Circuit or Prox Line alarm
Circuit disconnect.
Reconnect the circuit.
Humidity in proximal line.
Change where proximal line is connected to the circuit.
Move it from the connection at the patient wye (wet
environment) to an adapter placed directly on the inlet
of the humidifier chamber (dry environment).
No proximal inline filter in place.
Insert approved proximal inline filter (part number
HT6004701).
Inspiratory flow is too low, circuit
pressure does not rise fast enough
when the breath starts.
As appropriate, increase flow or change flow pattern in
Volume Control or speed up slope rise in Pressure
Control/Pressure Support.
