When a foreign body is present in the airway, if it is small, the patient can cough it out by himself. If the foreign body is large and there is significant breathing difficulty to reach the hospital immediately, the foreign body needs to be expelled with the help of surrounding objects. If the patient has the strength, he or she can press the upper abdomen against the back of a chair or a railing and repeatedly press hard to flush the foreign body out of the airway as far as possible. If you do not have the strength and need help from the surrounding people, you can hold the patient around, and then put your hands in a fist against the patient’s upper abdomen, with your thumbs on top of the upper abdomen, and impact the abdomen as hard as possible to make the patient expel the foreign body from the airway. If this does not work, the patient should be admitted to the hospital and the foreign body should be removed surgically. The more common clinical practice is to remove the foreign body through bronchoscopy, and if the bronchoscopy is not effective, open-heart treatment is required.
