Very Low FiO2 Alarm Troubleshooting

Very Low FiO2 activates when the monitored FiO2 is less than 18%. 

Follow these steps to troubleshoot this alarm:

1. Ensure the VOCSN air inlets are not blocked and there is adequate air flow around the device.
2. Remove any oxygen sources connected to VOCSN or the patient circuit.
1. If the Very Low FiO2 alarm resolves, troubleshoot problems with the oxygen source.
2. If the Very Low FiO2 persists, there may be a problem with the VOCSN oxygen sensor. Please fill out this form. One of our clinical specialists will contact you.
