Which component mixes the anesthetic with carrier gases?

The anesthetic vaporizer is designed specifically to mix volatile anesthetic agents with carrier gases, typically oxygen and nitrous oxide. This component functions by vaporizing the liquid anesthetic and delivering it in precise concentrations into the gas flow being delivered to the patient. The vaporizer's ability to accurately regulate the concentration of anesthetic ensures that the patient receives a consistent and safe level of anesthesia for their procedure.

While the flowmeter can measure the flow rate of gases, it doesn't mix the anesthetic with the carrier gases; rather, it allows for the adjustment of gas flow rates. The scavenging system is responsible for removing excess anesthetic gas from the operating room environment to minimize exposure for staff, and the pressure-reducing valve is used to decrease the high-pressure gas from the tank to a usable level, but does not mix anesthetics with gases. The specific role of the vaporizer is crucial to the delivery of anesthesia, which is why it is the correct choice in this context.
