Procedure
Removal
i) Disconnect the return hose that is connected to the Exhalation Valve Housing (3).
ii) Gently unscrew the Exhalation Valve Housing (3).
iii) Remove the Exhalation Valve Diaphragm (2) off the spigot (4) carefully to avoid damage, ie. tears
and distortion.
Cleaning
iv) Thoroughly clean the Exhalation Valve Housing (3) and Exhalation Valve Diaphragm (2) either in
running hot water or in a detergent solution followed by a thorough rinsing under running water.
v) Dry both parts thoroughly and check them for damage prior to reassembly.
CAUTION: Ensure that the valve seat rim (5) is not damaged. A damaged valve seat rim will result in a
loss in passive PEEP performance. (PEEP achieved in CMV + PEEP mode).
Re-assembley
Replace any components that are damaged or worn (see Equipment Required section).
WARNING:
To avoid the risk of the exhalation valve diaphragm
remaining depressed against the valve housing and
resulting in continuous pressure loss from the patient
circuit, avoid depressing the center of the diaphragm
during fitment. Following the replacement procedure,
ensure that the center of the diaphragm is is not
depressed and always perform a functional check.
vi) Ensure that the Exhalation Valve Diaphragm is correctly mounted on the spigot with the centre
raised projection (6) of the diaphragm pointing outwards.
At this stage a quick check for the functionality of the diaphragm can be performed as
follows-:
1. Ensure that an air or oxygen supply is available.
2. Set the Inspiratory Pressure and PEEP/CPAP controls to the minimum settings.
3. Set the Function Selector Switch to CMV + PEEP and the B100 will commence
cycling which in turn will oscillate the diaphragm.
This confirms that the diaphragm has been correctly installed.
