What are the fittings that a hose connects to in an anesthetic machine?

The selection of the vaporizer outlet port and the common gas outlet as the correct fittings for a hose in an anesthetic machine is based on their specific roles in the delivery of anesthetic gases.

The vaporizer outlet port is where the gas, after being mixed with the anesthetic agent, exits the vaporizer and enters the breathing circuit. This port is crucial because it allows for the precise delivery of anesthetic vapor mixed with the carrier gas (typically oxygen or nitrous oxide) to the patient.

The common gas outlet serves as the connecting point where the gases, now ready for administration, are routed from the anesthetic machine to the patient's airway via different components such as the breathing circuit. This common gas outlet ensures that gases from multiple sources can converge appropriately before being delivered to the patient.

Understanding this connection is vital for effective anesthesia management and ensures that the delivery of anesthetic gases is both safe and efficient during surgical procedures. The other options do not accurately represent the critical connections that facilitate the proper functioning of the anesthetic machine's gas delivery system.
