Anesthesia machines are specialized medical devices used to deliver anesthesia to patients during surgical procedures. They mix gases, such as oxygen and nitrous oxide, with anesthetic vapors to ensure patients remain unconscious and pain-free. These machines also monitor vital signs, including heart rate and blood pressure, to ensure patient safety throughout the procedure. The components of an anesthesia machine include a gas delivery system, a vaporizer for anesthetic agents, and a ventilator to assist with breathing if needed. Anesthesia machines are essential in operating rooms, helping anesthesiologists manage patient care effectively during surgery.
