In one of the medical colleges there was a usual lecture on nursing. Was led by her not a young lecturer, a former practicing surgeon. During his life he did more than one operation, he was in different parts of the globe, where it was required to render friendly assistance after various natural disasters. And the first 2 years after the institute in general worked for the "first aid". All this made him in the eyes of students an authoritative person. The future nurses were very fond of the teacher himself, and his useful and interesting lectures, and they never skipped. The elderly surgeon reciprocated them. So today on the agenda seems to be a common theme, "Why is the nose, blood, causes and first aid", and in the audience complete silence and attention. "So, girls, this question is very important for you all, you will get married, you will have children, and you will have to be able to cope with this problem. After all, the nose suffers most often and is the most dangerous and bloody place of our body. Now I will tell you why the blood comes from the nose, then I will answer your questions, and then explain the nuances of first aid. "
The reasons for which comes from the nose of the blood
"So, there are a lot of reasons for blood coming from the nose.
- Mechanical effect. I think that this reason is familiar to all from childhood. The noses probably broke everything. Who fell from the bicycle, to whom a friendly fist helped. And someone was a big fan in childhood, poking at the nose in the nose. In short, any excessive shock or mechanical force that acts on the mucous membrane of the nose causes bleeding. After all, there are more blood vessels here than in any other organ, and their walls are thin and weak. And there is nothing strange in that they are easily damaged.
- Vitamin C deficiency. As you know, vitamin C strengthens the walls of blood vessels. If it is not enough, the vascular walls become loose and brittle. This fact and can be an answer to the question of why often goes nose blood.
- Hypertension. Elevated arterial or intracranial pressure can also cause nasal bleeding. But this is more of a blessing than a disaster, for it is better to lose some blood and lower blood pressure than to get a stroke. By the way, most often pressure drops happen from 4 to 6 o'clock in the morning. This fact explains why some people bleed from the nose in the morning.
- Violation of blood coagulability. Typically, this is due to a violation of the liver or blood-forming organs. In such people it happens that the blood from the nose goes clots. This is explained as follows: platelets try to form the wound, and the bleeding resumes. Blood, flowing out, brings the thickened particles out.
- Hereditary predisposition. Happens and such, Like in an organism all in norm or rate, but sometimes from a nose there is a blood. If a mom or dad, grandmother, grandfather or other relatives have this phenomenon also takes place, then it is a hereditary predisposition. There is nothing terrible here, you just have to watch yourself and be able to stop bleeding on your own.
- Diseases of the nasal cavity. Allergic rhinitis, when the mucous membrane becomes swollen, as well as the curvature of the nasal septum, can also cause the flow of blood from the nose. Well, here it is necessary either to do the operation, or to eliminate the allergen. There is no other way out.
So I told you the main reasons why the nose is bleeding, do you have any questions? " The students answered that they understood everything. "Well, then we turn to first aid."
First aid for nasal bleeding
"If you or someone else's nose went blood, the main thing is not to panic. The patient should be seated on a chair with a back so that he does not fall, and ask him to tilt his head slightly forward. Let some amount of blood come out, so we will protect a person from a stroke if the cause of bleeding was hypertension. Then, a cold should be applied to the bridge of the nose. It can be an ice pack, a cold compress or a piece of meat from the freezer. Under the influence of cold, the vessels narrowed and the blood flow ceases. Another option is to clamp the wing of the nostril, from which the blood flows, with a finger and hold it for 5 minutes. But if the blood goes from the nose long and hard, you should immediately call an ambulance. Stop such bleeding is only possible in a hospital. That's it. Now you know why the nose is bleeding, and what to do about it. Teach a lecture, tomorrow I will ask, and today, good-bye. "
