The same vaporizer cannot be used for all anesthetic gases.

The same vaporizer cannot be used for all anesthetic gases.

• A. True
• B. False
• C. Only in some machines
• D. It depends on the gas

Answer: (A)

Vaporizers are designed to deliver a precise concentration of a specific volatile anesthetic by exploiting that agent’s vapor pressure and required temperature. Each agent has a different vapor pressure and often needs a different operating temperature to achieve the intended delivered concentration. If you used the same vaporizer for a different agent, the output would be inaccurate, potentially causing under- or overdose. Some agents, like desflurane, even require a specially heated vaporizer, underscoring that one device cannot reliably handle all gases. There can also be cross-contamination if a vaporizer isn’t properly flushed or replaced when changing agents. Because of these factors, the statement is true: the same vaporizer cannot be used for all anesthetic gases.
