Low alarms beep after 5 minutes, even if O2 flow is increased have tried with and without humidity. Alarm continues to beep. Any suggestions.
The low alarms on the 3B Medical Stratus 5 could be caused by:
1. Low oxygen purity (less than 82%) — indicated by a red LED and continuous audible alarm.
2. Low flow rate — even if oxygen flow is increased, the output may still be too low due to a kinked cannula, blocked outlet, or loose humidifier cap.
3. Sensor failure — NTC temperature sensor error can trigger alarms.
4. Power supply issues — voltage below 85% of rated can cause malfunction.
Check for obstructions, tighten connections, and verify oxygen purity and power supply.

Low alarm comes on after 5 minutes and stays on even if O3 flow is increased.
The low alarm on a 3B Medical Stratus 5 could activate after 5 minutes, even when the O3 flow is increased, due to low oxygen output flow. This may be caused by:
- Blockage or restriction in the tubing or flow path
- Oxygen purity falling below 82%
- Sensor errors or malfunction
- High temperature or pressure abnormalities
Adjusting the flow-meter or checking for blockages may help. If the issue persists, contact a healthcare professional.
