Frequently Asked Questions
My pop off valve is sticking what can I do?
Remove the pop off valve from the Absorber Head and use a Q-Tip with some alcohol to clean out the bottom of the pop off valve. Often issues with pop off valves sticking can be attributed to Sodalime/Beralime dust becoming lodged in the bottom of the valve over time. Dust accumulation combined with air moisture can make result in sticking.

My Flowmeter is turned off but the ball still shows flow.
This is a common problem that can occur over time with wear and tear or in some cases from over tightening of the flowmeter control knob.
In order to fix this issue first make sure that the flowmeter control knob is turned snugly but not excessively to the off position. Using a 1/16th allen wrench remove loosen the two small set screws in the knob, the knob should slide off freely exposing the needle valve post. Gently turn the post to the right slightly, the flowmeter ball should settle at zero. Next slide the knob back on the post and tighten the set screws snugly. Your flowmeter should now be functioning normally. If this process fails to fix your flowmeter the needle valve may be worn or broken.

Standard Maintenance Leak Test
Occasionally it is recommended to perform a basic leak test of your anesthesia machine to make sure that it is functioning properly.
In order to perform a leak test you must first verify that your flowmeter is turned off and popoff valve is closed. Your machine should also have a breathing bag and tubes attached. Next cover the open end of of the breathing tubes to create a seal and depress the flush valve until approximately 40CM H2O is shown on the absorber manometer(taking care not to over-pressurize your breathing bag). Continue sealing the breathing tubes and monitoring the manometer pressure reading. Pressure should not decrease more than ~10CM H2O in ~15 seconds. If your machine fails the pressure test you should first check that your breathing bag is in good condition free of cracks or holes. If it still fails the black rubber tubing on your machine may need to be replaced. Check the hoses for cracking or brittleness.
