1) Choose the appropriate size of the mask for the patient;

2) Take out the anesthesia mask from the package, align the bottom of the mask with the back of the patient's lower lip, and gently buckle the anesthesia mask to cover the patient's mouth and nose;

3) Buckle the mask with your thumb, index finger and middle finger. If necessary, lift the patient's chin with the remaining fingers;

4) There is no need to press the mask down to ensure the sealing: the material of the edge part and the design in line with the anatomy of the human face ensure that the sealing can be achieved with the minimum pressure. Finally, the mask is fixed to the patient's face with a fixing belt.
