A sputum suction tube has a powerful suction effect and can quickly clean up respiratory secretions. It is recommended to use a disposable sputum suction tube under the guidance of a doctor through the following steps.

1. Check if the suction catheter is unobstructed and allow the patient to turn their head slightly back. If the patient is unconscious, they need to use a tongue depressor to open their mouth, and then insert the suction catheter into the throat. When the patient is inhaling, insert the suction catheter into the trachea. If it is difficult for the patient to aspirate phlegm from the oral cavity, it can be inserted through the nasal cavity.

2. Before inserting the suction tube, turn on the suction switch, but loosen the side hole of the T-shaped tube. When the suction tube is inserted into the trachea at a certain depth, immediately press the closed side hole to suction. When aspirating phlegm, the suction tube should be slowly lifted from bottom to top and rotated left and right to remove phlegm. To prevent damage to the mucous membrane by fixing it or lifting and inserting it up and down for suction. After removing the suction tube, rinse the sputum inside the tube with water to avoid obstruction. Turn off the aspirator switch

3. Sucking sputum should not exceed 15 seconds at a time. After suctioning, clean the nasal cavity and oral cavity, and check for any damage to the mucosa. Each time suctioning, replace the sterile suction tube.

Pay attention to the oxygen concentration before and after suction, and observe the patient's vital signs before and after suction. Once any physical abnormalities or discomfort symptoms are found, the operation should be stopped immediately
