Checking the emergency o2 flow and gas i presume is what they do in the service?

the obvious i guess is to make sure that it is working? and that when you turn on your 02 and gas that nothing is sticking and it all switches on and off properly and that your ball/bobbin is moving and not stuck in the chamber. :)

Thats great. How would you check the anaesthetic gas flow regulator? And checking emergency oxygen flow?

To leak test circuit:

· attach circuit to machine turn on 02.

· ensure 02 is coming through the circuit.

· close off the valve entirely.

· block your patient end.

· Reservoir bag should over-inflate as gas should not be able to escape. Showing that there is not a leak in your circuit.

Obviously open the valve once you have tested the circuit J

Ensuring effective gas scavenging I presume is firstly ensuring a good fitting ET tube to avoid leakage in the first place and having an “active scavenge” relying on negative pressure to draws it out, measuring/monitoring this would be by means of actually smelling the gas and anaesthetic monitor worn for x amount of anaesthetic time (looks like a pen).

Have always checked seals with some watery hibiscrub to see if any bubbles form- showing a leak- not sure if this is a recognised way of doing things but it works!

We clean our circuits with medis and hang them to dry (once re-assembled) Milton could work for this too.

Annual services on anaesthetic machines advised- more frequently if you are having issues.

Hope this helps x
