True or False: One flowmeter can control multiple gases.

• A. True
• B. False
• C. Only with additional components
• D. It depends on the machine model

Answer: (B)

The statement is false because, in an anesthesia machine, each flowmeter is specifically designed to control the flow of a single gas. Flowmeters function as precision devices that measure and regulate the amount of gas delivered to the patient, and they are calibrated for the unique properties of each gas, such as density and viscosity.

Using one flowmeter for multiple gases would lead to inaccurate flow readings and potentially hazardous situations for patient care. In practice, an anesthesia machine is equipped with separate dedicated flowmeters for each type of gas, including oxygen, nitrous oxide, and various volatile anesthetics, ensuring safe and accurate delivery of anesthetic agents.

In certain systems, while it might be possible to route gases through a single pathway, the flow measurement and regulation would still need to be handled individually to maintain precision and safety. Therefore, the correct answer reflects the importance of dedicated flowmeters in ensuring patient safety and effective anesthesia management.
