[0002] Suctioning is a commonly used emergency treatment measure in the emergency department. When the patient has sputum sound, difficulty breathing or sputum is too thick to cough up, auxiliary suction methods are needed to relieve symptoms. The method is usually to insert a suction tube into the patient's trachea to suction the sputum. Suctioning can reduce the risk of suffocation and is also beneficial to infection control. The commonly used suction tool is the suction pump, which uses the principle of negative pressure to suction sputum.
