Anaesthetic masks are medical devices used to deliver anesthetic gases to patients during surgical procedures. They cover the nose and mouth, creating a sealed interface to ensure proper gas delivery. Anaesthetic masks come in various sizes and designs to accommodate patients of different ages and anatomies. They are typically made of transparent material, allowing healthcare professionals to monitor the patient's face during anesthesia administration. These masks are essential in maintaining a patient's airway, providing oxygenation, and controlling the delivery of anesthetic gases, ensuring safe and effective anesthesia induction and maintenance.
