High PEEP Alarm (or High EPAP in Bi-Level Mode) Troubleshooting Follow

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:

  1. If using an Active patient circuit, ensure the multilumen tube is tightly connected to VOCSN and the exhalation valve.
  2. Note that if the alarm occurs while the patient is breath stacking, it is working as intended.
  3. Check for auto-triggering and adjust the Flow Trigger control setting if needed. 
  4. If the problem persists, replace the patient circuit.
