High PEEP (or High EPAP in Bi-Level Mode) activates when the monitored PEEP is greater than PEEP plus the set High PEEP alarm limit.
Follow these steps to troubleshoot this alarm:
- If using an Active patient circuit, ensure the multilumen tube is tightly connected to VOCSN and the exhalation valve.
- Note that if the alarm occurs while the patient is breath stacking, it is working as intended.
- Check for auto-triggering and adjust the Flow Trigger control setting if needed.
- If the problem persists, replace the patient circuit.
