The purpose of the high pressure regulator is?

Answer 31

To reduce high pressure from a tank to a working pressure

Question 32

Where is the high pressure area on a diagram?

Answer 32

where are the gas tanks are at. The most upstream area.

Question 33

If contamination or a construction crossover of piped medical gases in the operating room is suspected, which of the following actions should be taken?

Answer 33

The machine's back up cylinder valve should be opened and the anesthesia machine should be disconnected from the hospital's pipeline supply

Question 34

Tanks on the anesthesia machine should remain closed when utilizing pipeline gases for what reasons?(choose 2)

Answer 34

So the anesthetist maintains a reserve supply of oxygen at hand if pipeline supply fails So the low oxygen pressure alarm will sound if pipeline supply fails, prior to any tank usage

Question 35
