- What is the anesthesia technician's first action when the oxygen supply failure alarm sounds?
Show answer
Immediately open the emergency backup oxygen cylinder and verify oxygen flow to the patient.- What safety device automatically cuts off nitrous oxide and other gas flow when oxygen pressure drops below a threshold?
Show answer
The oxygen failure protection device (fail-safe valve).- What color are medical oxygen cylinders in the United States?
Show answer
Green.- What color are nitrous oxide cylinders in the United States?
Show answer
Blue.- What safety system prevents an oxygen regulator from being attached to the wrong gas cylinder?
Show answer
The pin index safety system (PISS).- What safety system prevents pipeline hoses of different gases from being connected to the wrong wall outlet?
Show answer
The diameter index safety system (DISS).- Approximately what pressure does a full E-cylinder of oxygen read?
Show answer
About 1900 to 2200 psi.- What color change in soda lime CO2 absorbent indicates it is exhausted and needs replacement?
Show answer
It turns violet (purple).- What is the recommended action if CO2 absorbent is suspected of being desiccated?
Show answer
Replace the absorbent before use.- A rising inspired CO2 reading on capnography during a case suggests failure of what circle system component?
Show answer
A unidirectional (one-way) valve.- What is the most common cause of a sudden loss of the capnography waveform during a case?
Show answer
Esophageal intubation or a circuit disconnection.- What test checks the anesthesia machine's breathing circuit for leaks by pressurizing it to about 30 cm H2O with the APL valve closed?
Show answer
The positive pressure leak test.- What test checks the anesthesia machine for leaks between the flowmeters and the common gas outlet?
Show answer
The negative pressure leak test.- What part of the anesthesia machine does the high pressure leak test check?
Show answer
The system from the gas cylinder to the first-stage pressure regulator.- What happens if the APL (adjustable pressure limiting) valve becomes stuck fully closed during manual ventilation?
Show answer
Circuit pressure rises rapidly, risking barotrauma to the patient.
