ISOLATE A LEAK DURING LEAK TEST PROCEDURE NUMBER 2
When you are performing leak test number 2 and the flow meter shows a flow
after you close the cylinder valves, you must troubleshoot the malfunction. Refer to
a. Ensure that you have closed the flow control valve to its stop.
b. If you have closed the flow control valve and flow is still shown on the flow
meter, the flow control valve is defective. Remove and replace or repair the flow control
valve before returning the anesthesia device to service.
ISOLATE A LEAK DURING LEAK TEST PROCEDURE NUMBER 3A AND
If you are performing leak tests numbers 3A and 3B and the pressure does not
rise normally, there is a malfunction. With the adult re-breathing circuit (leak test 3A),
the pressure should rise to at least 35 mm Hg. With the pediatric partial re-breathing
circuit (leak test 3B), the breathing circuit pressure gauge should rise to 35 mm Hg or
higher. To troubleshoot the malfunction, perform the following procedure. Refer to
a. Attempt to correct a leak.
(1) Align the absorber canisters making sure they fit snugly against the
gaskets. Tighten the clamp screw being careful not to over tighten.
Make sure you have secured all hose and tubing connections.
Make sure that any protective closure devices you used in the test fit
Make sure you have securely tightened the vaporizer funnel plug and
Fully close the gas evacuator/relief valve.
(6) Make sure the threads on the neck of the breathing circuit pressure
gauge fit securely into the control head casting.
Make sure you have securely tightened all fittings and connectors.
(8) Make sure you have tightened the inhalation and exhalation check valve
window knurled ring retainers.
Make sure you have tightened the absorber drain spigot.
