People’s first reaction to a nosebleed is to tilt their heads, but this is not correct, to immediately sit down to blow the blood in the nasal cavity clean. The tilted head position during a nosebleed will cause the blood to flow backwards down the nasal passage to the throat due to gravity, and if it is swallowed into the stomach, it will stimulate the gastrointestinal mucosa and produce stomach discomfort and even vomiting. In addition, when the amount of blood in the nasal cavity is too much, it may flow back to the eyes from the nasolacrimal duct, resulting in bleeding from the corners of the eyes; when the amount of blood swallowed is too much and too urgent, it is also easy to choke into the trachea and lungs, resulting in respiratory obstruction. So, how should we deal with nosebleeds? To sit down immediately, blow the blood in the nasal cavity, and put the thumb on the side of the bleeding nose, the index finger pinch the movable tissue of the nose to compress the bleeding, the general acupressure time is 5-10 minutes, the strength of the acupressure, should be to feel nasal pain, while the bleeding person open mouth breathing is appropriate. A cold compress of wet towel or ice can be applied to the nose to shorten the hemostasis time. If it is still ineffective after 10 minutes, you should go to the hospital immediately.
