An anesthesia machine is a medical device used to deliver anesthesia to patients during surgical procedures. It combines several components, including a gas supply, vaporizer, and ventilator, to ensure that patients remain unconscious and pain-free. The machine allows anesthesiologists to control the dosage and mixture of anesthetic gases, ensuring patient safety and comfort. The machine typically includes monitors to track vital signs such as heart rate and oxygen levels. It is essential in operating rooms and is often used alongside other equipment, such as surgical tables and monitoring devices, to provide comprehensive care during surgery.
