Flowmeters: Flowmeters are used to control the flow of gases that are delivered to the patient. These meters are typically made of glass or plastic and have calibrated scales that allow the anesthesiologist to adjust the flow of gases based on the patient's weight and medical condition. Vaporizers: Vaporizers are used to convert liquid anesthetic agents into a gas that can be inhaled by the patient. The vaporizers are calibrated to deliver a specific amount of anesthetic agent, which is mixed with oxygen and delivered to the patient.

Breathing circuit: The breathing circuit is the part of the Anesthesia Machines that connects the patient to the machine. The circuit consists of a series of tubes, valves, and connectors that allow the gases to flow to the patient and the exhaled gases to be removed from the patient's lungs. Ventilator: The ventilator is a device that helps the patient breathe during anesthesia. The ventilator is connected to the breathing circuit and delivers a controlled amount of air to the patient's lungs.
