- What is the primary purpose of an anesthesia machine?
- To deliver a precise, controlled mixture of medical gases and volatile anesthetic agents to a patient
- What does the Pin Index Safety System (PISS) prevent?
- Attaching the wrong gas cylinder to a hanger yoke
- What does the Diameter Index Safety System (DISS) prevent?
- Misconnecting low-pressure gas hoses or fittings to the wrong gas source
- Which gas fills a green-colored cylinder in the US color coding system?
- Oxygen
- Which gas fills a blue-colored cylinder in the US color coding system?
- Nitrous oxide
- What color is an air cylinder in the US color coding system?
- Yellow
- What color is the oxygen pipeline hose in the US?
- Green
- What color is the nitrous oxide pipeline hose in the US?
- Blue
- Approximately what pressure does a full E-cylinder of oxygen read?
- About 2000 psi
- Approximately what pressure does a full E-cylinder of nitrous oxide read?
- About 745 psi
- Why does a nitrous oxide cylinder gauge stay roughly constant until the cylinder is almost empty?
- Because nitrous oxide exists as a liquid with vapor above it, and pressure reflects vapor pressure, not remaining quantity
- What is the function of the hanger yoke on an anesthesia machine?
- It holds and aligns a gas cylinder against the machine's gas inlet
- What does the first-stage pressure regulator in an anesthesia machine do?
- Reduces high, variable cylinder pressure to a lower, constant intermediate pressure
- What is the function of a flowmeter on the anesthesia machine?
- It controls and displays the rate of gas flow to the common gas outlet
- What is the common gas outlet?
- The point where all mixed fresh gases leave the anesthesia machine toward the breathing circuit
