Low FiO2 activates when the monitored FiO2 falls below the set Low FiO2 alarm limit.
Follow these steps to troubleshoot this alarm:
- Ensure the Low FiO2 alarm setting is appropriate for the delivered FiO2.
- Check to ensure the high‑pressure oxygen source is connected and is not depleted.
- Make sure the high-pressure oxygen source is turned on and is delivering oxygen.
- Verify the O2 Low-Pressure Inlet adapter is not installed (if low-pressure oxygen is not in use).
