Self Check Fault - Pneumatic System: O
2
Valve
Alarm triggers when the communication between the O
2
valve and the SPM fails
and the compressor is available to provide ventilation. The alarm will continue to
sound as a medium priority alarm until the user acknowledges that ventilation is
being provided using the compressor by setting the FIO
2
to 21%. At this time the
alarm priority changes to low. While operating in this state the user should
monitor the SpO
2
to ensure that adequate oxygenation is maintained. If low flow
O
2
is available it can be entrained through the Fresh Gas/Emergency Air Intake
port using the optional O
2
reservoir. Maintain an acceptable SpO
2
by adjusting
the O
2
supply up or down to increase or decrease the amount of O
2
delivered to
the patient.

Low O2 Supply Fault - Operation Switched to Compressor
Alarm triggers when the O
2
supply pressure is < 35 psig (241 kPa) and the
compressor is able to support ventilation. When this occurs the device begins
ventilation using the compressor. The alarm will continue to sound as a medium
priority alarm until the user acknowledges that ventilation is being provided using
the compressor by setting the FIO
2
to 21%. The alarm will cancel completely
when the user sets to 21%.
Note
: The device works with or without external O
2
. If O
2
is connected the device
will restart O
2
operation unless the supply pressure is
≥
40 psig (276 kPa). This
is done to prevent continuous cycling between alarms during the inspiratory
phase and no alarm during the expiratory phases. If low flow O
2
is available it
can be entrained through the Fresh Gas/Emergency Air Intake port using the
optional O
2
reservoir. Maintain an acceptable SpO
2
by adjusting the O
2
supply
up or down to increase or decrease the amount of O
2
delivered to the patient.

Gas Intake Fault - Operation Switched to O2 Supply
Alarm triggers when the Fresh Gas/Emergency Air Inlet is blocked so that the
compressor is not able to deliver a breath within ±10% of the current settings and
high pressure O
2
is available to support ventilation. When this occurs the
ventilator immediately switches to O
2
powered ventilation. To clear the alarm first
set the FIO
2
to 100% to acknowledge that the patient is being ventilated at
100%, clear the blockage and then set the FIO
2
back to the original value. Once
the blockage has been cleared operation with the compressor will restart. If the
blockage cannot be cleared, the alarm will resound, continue ventilation with
FIO
2
set to 100% and ensure an adequate supply of O
2
.
NOTE
: A high vibration
environment can trigger this alarm. If necessary, the user can activate the O
2
Reservoir mode while continuing to operate normally. This will suppress the
alarm.
