anesthesia circuit

An anesthesia circuit is a system used during surgery to deliver anesthetic gases and oxygen to a patient. It connects to a machine that controls the flow of these gases, ensuring the patient remains unconscious and pain-free. The circuit includes a breathing bag that helps maintain proper ventilation and a mask or endotracheal tube to connect to the patient's airway. It also has valves and filters to remove carbon dioxide and ensure a safe breathing environment. Overall, it's a vital component in providing safe anesthesia during medical procedures.
