Why does dry air make nosebleeds easy? What happened?

The microscopic blood vessels in the nasal mucosa are very densely distributed, are very sensitive and fragile, and can easily rupture and cause bleeding. Nose bleeding is common in preschool children. When the nasal cavity is too dry, the capillaries in it can rupture, causing bleeding. From a clinical point of view, 90% of nosebleeds are vascular bleeding caused by blood vessel rupture. In this regard, 1. Before stopping the flow, the blood clot should be blown out to avoid being unable to stop the bleeding due to the wound being unable to close.

2. Wet cotton with decongestant or nasal spray and stuff it into the nostrils to help stop bleeding. White vinegar will also work.

3. Use your fingers to pinch part of the nose meat and keep pressing it for five to seven minutes to help stop bleeding.

4. Sit up straight to prevent blood from flowing to your throat.

5. Ice application can promote blood vessel contraction and reduce bleeding.

6. After the blood coagulates, blood clots and scabs will form. It is best not to pick your nose at this time to avoid peeling off the scabs and causing recurrence of nosebleeds.

7. Apply antibiotic or steroid ointment to relieve itching and prevent mucus from drying and hardening.

8. If the left (right) nostril bleeds, raise the right (left) arm. The bleeding will stop in a few minutes.

9. Push the nose wing on the bleeding side toward the bridge of the nose and hold it there for 5 to 10 minutes to allow the blood to coagulate and stop the bleeding. If bleeding occurs on both sides, pinch both sides of the nose. After the nosebleed has stopped, there may be clots in the nostrils. Do not rush to remove them. Try to avoid sneezing and rubbing vigorously to prevent further bleeding.

10. When the patient's left (right) nostril bleeds, another person hooks the middle finger of the patient's right (left) middle finger and bends it hard. The bleeding can usually be stopped in tens of seconds; or use a cloth strip Prick the root of the patient's middle finger. If the left (right) nostril is bleeding, prick the right (left) middle finger. After the nosebleed stops, untie the cloth.

11. Take an appropriate amount of garlic, peel it and pound it into minced garlic, apply it on the soles of the feet, and wrap it with gauze to stop bleeding quickly.

12. Let the patient sit on a chair and soak his feet in hot water to stop nose bleeding.

13. If you have frequent nosebleeds, you need to go to the hospital for further diagnosis and treatment.

Patients don’t need to be too nervous. In most cases, they can handle it by themselves and stop the bleeding in time
