In clinical practice, there are two main functions of anesthesia face mask
1. Used for oxygen supply. For example, before performing intravenous general anesthesia intubation, the anesthesia face mask
will be used to cover the patient’s nose and mouth, allowing the patient to inhale high-flow pure oxygen, that is, pre-oxygenation, to increase the oxygen in the patient’s lungs The content provides sufficient time for the implementation of general anesthesia intubation. In addition, in a short operation, after the patient undergoes intravenous anesthesia, a mask can be used to give oxygen to the patient to assist the patient to breathe independently. When the patient has difficulty breathing and other emergency situations, the patient can be pressurized and oxygenated with a mask, and a temporary artificial respiration path can be established to buy time for the patient's rescue;
2. Use a face mask to administer anesthesia. When the patient needs to be inhaled for general anesthesia, the face mask will be used to cover the patient’s mouth and nose, allowing high-concentration oxygen and anesthetics to enter the body through the patient’s breathing, so as to achieve anesthesia. The purpose of the medicine.
