dont forgot backup cylinders and BVM as they would be needed for backup. In case pipeline supply issues or anaesthetic machine issues during induction or maintaince of anaesthesia.
You also have a basal flow rate of O2 on these machines which could potentially mask a small leak. Disconnections the O2 or turning the machine off would stop the basal flow rate.
There is a leak. I could see the bellows getting lower even from my screen. If you run the bellows test for a few more minutes you will see the bellows rise less and less. The size of the leak is proportionate to what you are causing it with. A missing gasket isnt going to leak as much as say an open bellows case or hole in your circuit. The current test is valid.
That's a very creative yet simple way of explaining these check tests , I totally understand them better than I ever did . It would be great if u could do a video explaining the most common breathing circuits used in the o.t .
