VM 580 EXAM PRACTICE QUESTIONS AND
100% CORECT ANSWERS!!
What happens if the APL valve is closed?
All exhaled gas is retained in the circuit and moved toward the CO2 absorber.
What happens if the APL valve is opened?
Some gas would exit, but the rest would recirculate through the system.
What is the purpose of the anesthetic scavenger system?
To remove waste anesthetic gases from the circuit and vent them out of the building.
What is the purpose of the CO2 absorbent canister?
To remove CO2 from expired gases
What is the function of soda lime in the CO2 absorbent canister?
To absorb CO2
Why is the breathing circuit called a 'rebreathing' circuit?
Because expired gases are mixed with fresh gases
What is the purpose of an anesthesia leak check?
To ensure there are no leaks in the breathing circuit
What should be done before performing an anesthesia leak check?
Connect O2 supply and attach breathing circuit
, What should be done with the adjustable pressure limiting valve (APL) during an
anesthesia leak check?
Close it
What pressure should be reached in the circuit during an anesthesia leak check?
20 cmH2O
What should be done if the pressure in the circuit drops during an anesthesia leak check?
Quantify the leak by increasing oxygen flow rate
What should be done after quantifying the leak during an anesthesia leak check?
Turn off the flowmeter
How should the pressure in the circuit be released after an anesthesia leak check?
By opening the APL valve
What should be done after completing an anesthesia leak check?
Replace the 'anti-PEEP' valve
How do you disconnect the central oxygen source?
Press the connector toward the wall and push the green oxygen release button.
What is the high pressure zone of the anesthesia machine?
E-tank, 1900-2200 PSI, ~660 L of O2, color-coded, made of steel or aluminum, safety features
What is the purpose of the hanger valve and pin index safety system?
To securely attach the E-tank to the machine and prevent accidents
