Try not to lift your head when you have a nosebleed, mainly for the following reasons: First, after lifting your head a large amount of blood enters the throat from the posterior nostril, which can easily choke into the trachea, causing the patient to choke and cough and other discomfort. If there is more bleeding, it is easy to induce aspiration pneumonia and breathing difficulties in patients. Secondly, a large amount of accumulated blood when lifting the head is easily swallowed into the stomach by the patient, and since the blood is not easily digested in the stomach, the patient is prone to nausea, vomiting and other discomfort in the stomach. For patients with nosebleeds, it is recommended to try to maintain a forward leaning head down position so that blood can flow out from the front nostrils without causing the patient to suffocate, and if a small amount of blood enters the throat, it is also convenient for the patient to spit it out, and at the same time, it is recommended that the patient breathe with an open mouth to avoid symptoms such as breathing difficulties. For patients with nosebleeds, it is recommended to go to the ENT department for nasal tamponade or electrocoagulation to stop the bleeding.
