2.
Examine the silicon diaphragm for kinks, cuts, holes, or inconsistencies in the material. See
Figure D-2.
If the diaphragm is kinked, relax the silicone diaphragm with your fingers, ensuring that
there are no longer any kinks (this usually takes a few seconds).
If the diaphragm has a hole or cuts, replace the patient Circuit.

3.
Carefully re-seat the silicone diaphragm in the exhalation valve seat. Tap around the silicone
diaphragm lightly to ensure that kinks do not develop when closing the exhalation valve. See
Figure D-3.
4.
Locate the top of the exhalation valve, taking care not to touch the silicone diaphragm. Ensure
that the barbed end with tubing is pointing into the FLOW direction. Apply enough pressure
to
snap
the exhalation valve cover in place.

Test the patient circuit with a test lung before using it with a patient. If it fails to perform,
replace the patient circuit.
