The anesthesia mask is primarily used for oxygen supply. Before the general anesthesia intubation is performed, the patient's mouth and nose will be covered with anesthetic face mask, allowing the patient to inhale high-flow pure oxygen through the anesthetic mask to increase the oxygen content in the patient's lungs, to provide sufficient time for the subsequent endotracheal tube intubation.
