Low FiO2 Alarm Troubleshooting

Low FiO2 activates when the monitored FiO2 falls below the set Low FiO2 alarm limit.

Follow these steps to troubleshoot this alarm:

1. Ensure the Low FiO2 alarm setting is appropriate for the delivered FiO2.
2. Check to ensure the high‑pressure oxygen source is connected and is not depleted.
3. Make sure the high-pressure oxygen source is turned on and is delivering oxygen.
4. Verify the O2 Low-Pressure Inlet adapter is not installed (if low-pressure oxygen is not in use).
