Different methods should be chosen according to the different causes of tracheal obstruction, and the common ones are coughing forcefully, emergency tracheotomy, and endotracheal stent placement. 1. Coughing with force: For foreign bodies, phlegm, blood clots, etc. obstructing the organs, coughing with force and back-patting can be used to dislodge the obstructing substances and relieve the tracheal obstruction. 2. Bronchoscopy: Remove foreign bodies, aspirate sputum or stop bleeding through bronchoscope. 3. Tracheotomy: Tracheotomy can be chosen for complete tracheal obstruction in case of emergency to quickly restore ventilation. 4. Endotracheal stenting: For tumors and other occupying lesions, such as cervical esophageal cancer, goiter compressing the trachea, endotracheal stenting can be chosen to relieve tracheal obstruction. For tracheal obstruction, it is necessary to solve the obstruction as soon as possible to restore ventilation. If the obstruction cannot be relieved by coughing and patting the back, it is necessary to consult a doctor immediately, so as to avoid delaying the treatment, which may lead to cerebral hypoxia and other serious consequences.
