Action
1. Check the patient's status.
2. Check for leak.
3. Check the oxygen supply and connections to the device.
4. Perform a Learn Circuit to recalibrate the oxygen sensor.
1. Check the patient's status and airway.
2. Inspect the circuit and the expiratory valve for obstruction or leaks.
3. Perform a Learn Circuit.
1. Check the patient's status and airway.
2. Inspect the circuit for obstruction.
3. Perform a Learn Circuit.
1. Check the patient's status.
2. Inspect the circuit and the expiratory valve for obstruction or leaks. When in use,
check for obstructions in proximal lines.
3. Perform Learn Circuit.
1. Check all circuit connections, especially the patient interface and the proximal sense
line.
2. Inspect the circuit and expiratory valve for damage or secretions.
3. Perform a Learn Circuit.

2. If the alarm persists, use another SpO
1. Check that the mask vents are clear and unobstructed.
2. Check the mask type setting.
3. Perform a Learn Circuit.
Note: This alarm could be impaired if supplementary oxygen is added at the mask or into
the circuit.
1. Check the patient's status and airway.
2. Inspect the circuit and the expiratory valve for obstruction. When in use, check for
kinks in proximal lines.
3. Check the circuit for water.
