If the patient tilts his head when he has a nosebleed, the bleeding volume is particularly large, which can easily lead to blood flowing into the posterior nostril and even accidentally swallowing into the stomach, and the patient may have obvious nausea and vomiting after a while, and the bleeding in the nasal cavity may be more serious if the patient exerts himself too hard, thus forming a vicious cycle. And if the patient does not come out of the nosebleed, it will exist inside the nostrils, resulting in the formation of many clots in the nasal cavity, which will easily affect the patient’s ventilation and lead to lack of oxygen, the patient will have a feeling of suffocation, and sometimes the clots will hang down to the posterior nostril, and the patient’s pharyngeal cavity will also have an obvious foreign body sensation, so try to let the nosebleed out without tilting your head, and then take the time to stop the bleeding.
