Anesthesia machine is an essential medical device used to deliver controlled concentrations of anesthetic gases and oxygen to patients during surgical procedures. It supports the administration of general anesthesia and helps maintain the patient's breathing throughout surgery. Depending on the model, it may feature an integrated ventilator, breathing system, gas flowmeters, vaporizer, patient monitoring connections, and safety alarms. Its design enables anesthesiologists to manage gas delivery and ventilation according to the patient's clinical needs.
