3030 Gas Intake Fault
Alarm triggers when the Fresh Gas/Emergency Air Inlet is blocked so that the compressor is not able to
deliver breaths within ±10% of the current settings, high pressure O
the user has set the FIO
inal value. If the blockage is cleared operation with the compressor will restart. If the blockage is not
cleared, the alarm will resound, set the FIO
of O . It is possible for this alarm to be a false alarm that is triggered in a very high vibration environment or

if the device is not mounted correctly. If the alarm does not resolve contact the service center for additional
information.

3031
Intake Restricted
Alarm triggers when the Fresh Gas/Emergency Air Inlet is blocked but is still capable of delivering breaths
within ±10% of the current settings. This could be caused by an external blockage or a dirty/wet external or
internal filter. If the blockage is cleared the alarm will automatically cancel. Refer to instructions for chang-
ing the internal filters. If the problem does not resolve contact the service center for additional information.
On rare occasions, this alarm can be triggered by a patient with a very high inspiratory demand. In this
case increase the rise time or shorten the inspiratory time to increase the inspiratory flow rate.
Mitigation/Info: Clear Fresh Gas Intake, Check Filter for Moisture or Dirt, OR, Manage Settings / Inspiratory
Demand, **Manually Ventilate Patient**
3032 Self Check Fault
Alarm triggers when communication between the Fresh Gas/Emergency Air Inlet pressure sensor is lost.
Normal operation can continue but, if the condition is not cleared by powering off and restarting the device
should be replaced when appropriate as. When used during this alarm condition the user should be sure to
keep the Fresh Gas/Emergency Air Inlet clear and ensure that external filters are checked regularly.
Mitigation/Info: Pneumatic Sensor, Ventilator Operating, Unable to Detect Inlet Obstruction, **Contact Ser-
3041 High O2 Supply Fault
Alarm triggers when the high pressure O
automatically cancels when the supply pressure is <80 psig (552 kPa). Pressure above 87 psig (600kPa) could
result in a catastrophic failure, harm to the patient and/or damage to the device. The user should reduce the
O supply pressure, sometimes this requires replacing the regulator that is not functioning correctly. If the
2
pressure cannot be reduced and a low flow device like a flow meter is available the user can provide supple-
mental O via the optional low flow O
2
ensure that the pressure does not rise further.
Mitigation/Info: Decrease O2 Supply Pressure, Replace Regulator, Connect Low Flow O2, Monitor SpO2
3073 Tubing Compliance Fault
Alarm is triggered when the tubing compliance correction shows that it is >the set tidal volume indicating that
the patient may not be receiving the appropriate tidal volume. In this case the user should assess the patient
and settings. Consult the attending physician if there are questions about how to configure the ventilator cor-
rectly to support the patient.
Mitigation/Info: Calculated Compliance Volume Larger than Delivered Volume, Check Tubing Compliance vs.
Circuit
3091 AutoPEEP
Alarm triggers when the exhaled flow from the patient continues throughout the expiratory period causing the
expiratory control valve to cycle throughout the period to maintain the baseline pressure. When this occurs the
user should increase the expiratory period by decreasing the inspiratory time, decreasing the breathing rate or
both. The physician should also be consulted as this alarm is an indication that Auto-PEEP is occurring. Note:
at startup, this alarm is off. The user can choose to activate the alarm if they believe the patient is at risk of
Auto-PEEP using the Alarm Configuration submenu that is access using the Main Menu.
Mitigation/Info: Increase Expiratory Time, Decrease Inspiratory Time, Decrease Respiratory Rate, Disable
