Troubleshooting -- Infant/Pediatric Patient Circuits
If there are circuit-related alarms during trigger set up or initial use, such as Disconnect, PEEP
Leak, Low Airway Pressure, or Incomplete Exhalation, check all circuit connections and the
exhalation valve.
Figure D-7 Infant/Pediatric Patient Circuit Connections
If the exhalation valve is not performing, manually ventilate the patient and perform the
following procedure:
1. Using a hemostat or a tongue blade, carefully open the exhalation valve as we show in the
following illustration. Remove the top cover first, and then remove the silicon diaphragm.
Place the silicon diaphragm in a clean area.
Figure D-8 Removing Silicon Diaphragm-- Infant/Pediatric Patient Circuit
2. Examine the silicon diaphragm for kinks, cuts, holes, or inconsistencies in the material.
If the diaphragm is kinked, relax the silicone diaphragm with your fingers, ensuring that
there are no longer any kinks (this usually take a few seconds).
If the diaphragm has a hole or cuts, replace the patient Circuit.
