SEE Anesthesia Machine Questions
with 100% Correct Answers
High Pressure System Correct Answer: -cylinder and regulators
-hanger yoke, yoke block with check valves, cylinder pressure gauge, cylinder
pressure regulators
-O2 cylinder pressure 1900 psi
Intermediate Pressure
Pipeline = 50psi (O2 drops from 1900psi)
Tank = 45psi Correct Answer: -begins at pipeline and ends at flowmeter valves
-pipeline inlets
-pressure gauges
-o2 pressure failure device
-o2 second stage regulator
-o2 flush valve
-ventilator power inlet
-flowmeter valves
low pressure system
, -slightly above atmospheric but variable Correct Answer: -begins at flowmeter
tubes and ends at common gas outlet
-flowmeter (thorpe) tubes
-vaporizers
-check valve
-CGO
low pressure leak test (negative pressure test) Correct Answer: -assess integrity of
low pressure circuit from flowmeter valves to the common gas outlet
-attach bulb to CGO and create negative pressure
-bulb should not inflate
-best way to detect a vaporizer leak
high pressure test Correct Answer: -close APL valve, pressurize circuit to 30
cm/H2O and observe airway pressure gauge (should remain constant)
5 tasks of oxygen Correct Answer: 1) O2 pressure failure alarm
2) O2 pressure failure device (failsafe)
3) O2 flowmeter
4) O2 flush valve
5) ventilator drive gas
