When you have a nosebleed, try not to tilt your head, because tilting your head has two main disadvantages: 1, the blood can easily pass through the nasopharynx, pharynx and throat into the trachea, leading to severe choking and coughing, which can easily lead to the emergence of aspiration pneumonia. 2, when the patient tilts his head back, the blood can easily enter the stomach, leading to the emergence of heartburn and gastric discomfort, etc. If the patient has a nosebleed, he can pinch his nose with his thumb and forefinger, then lower his head a little and keep it in a forward position. If the patient has a nosebleed, the patient can pinch the nose with the thumb and forefinger, then lower the head a little, keep leaning forward, and open the mouth to breathe. If there is blood in the mouth, try to spit out the blood to avoid the blood flowing into the throat or trachea. Clinically, if the patient can not stop bleeding by pinching the nose, it is recommended that the patient go to the ENT clinic as soon as possible, and the doctor can do nasal expansion sponge tamponade to stop bleeding, or endoscopic electrocoagulation to stop bleeding.
