The function of anesthesia mask

  Anesthesia mask is an indispensable tool for general anesthesia. There are two main functions of anesthesia mask:
  1. It is used for oxygen supply. For example, before intravenous general anesthesia is inserted, the 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 content in the patient’s lungs , Provide 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 nose and mouth, allowing high-concentration oxygen and anesthetics to enter the lungs through the patient’s breath, thereby achieving anesthesia Purpose of administration
