Is oxygen or anesthesia mask inhaled?

　　In clinical use, anesthesia mask is usually used for anesthesia with two main functions: oxygen supply; Anesthesia is administered.

　　General anesthesia includes intravenous anesthesia, gas inhalation anesthesia and intravenous inhalation combined anesthesia. Intravenous anesthesia refers to anesthesia through intravenous channels; Inhaled gas anesthesia is a procedure in which a doctor holds a patient's nose and mouth tightly with a mask and inhales anesthetic drugs. Intravenous inhalation anesthesia is the combination of the above two methods in the whole process of anesthesia. Adult anesthesia is usually administered intravenously, while pediatric anesthesia is mostly administered with inhaled gas.

　　An anesthesia mask will be used to provide a high concentration of oxygen for preoxygenation during the transition between consciousness and anesthesia, known as induction.

　　After intravenous anesthesia, patients can become unconscious and unable to breathe while medics intubate their trachea to establish an airway. Adequate oxygen should be provided to the patient through anesthesia mask to increase oxygen content in the lungs, so as to provide sufficient time for endotracheal intubation during general anesthesia and ensure the patient's safety during anesthesia induction.

　　After the airway is established and before surgery, during anesthesia maintenance, the anesthesia mask will no longer simply provide oxygen, but will be combined with an inhaled anesthetic.

　　Therefore, at present, most general anesthesia is combined with intravenous inhalation anesthesia. It requires an anesthesia mask to provide sufficient oxygen before anesthesia, while during surgery, it requires an anesthesia mask to provide high concentration of oxygen and anesthesia, which can be breathed into the patient's body for anesthesia administration.
