Anesthesia masks are medical devices used to deliver anesthetic gases to patients during surgical procedures. They are typically made of soft, flexible materials that conform to the patient's face, ensuring a secure fit. The mask is connected to an anesthesia machine, which provides a controlled flow of oxygen and anesthetic agents. These masks come in various sizes to accommodate different age groups, from infants to adults. Anesthesia masks are essential for maintaining patient safety and comfort while ensuring that the anesthesiologist can effectively manage the patient's level of consciousness throughout the procedure.
