You can often see how a hero or heroine in a movie or play faints when he hears bad news or is very frightened. We usually associate fainting with events of this kind. But fainting can occur as a result of many reasons. People can faint due to being in a cramped and poorly ventilated room, due to hunger, fatigue, severe pain, emotional distress, and many other reasons. The immediate cause of fainting is a lack of blood supply to the brain. Since fainting occurs quite often, it is important to know what to do in such cases. A person who feels that he is about to faint should be laid down. If this is not possible, make him bend over so that his head is at the level of his knees. The purpose of these actions is to get more blood into the brain. If someone faints, lay them down and loosen tight clothing. Lower his head or lift his legs. Again, the goal is to increase blood flow to the brain. When a person regains consciousness, he can be given something tonic, such as coffee, or give him a sniff of ammonia. Sometimes a person loses consciousness for some other reason. For example, from a blow to the head, shock, sunstroke, overheating, or even poisoning. There are two types of unconsciousness, in which different assistance is provided. One of them is the "red" unconscious state. At the same time, the face turns red, and the pulse increases. The patient should be placed with the head and shoulders slightly raised. A cold compress should be placed on the head. In the case of "white" unconsciousness, the face turns pale, the skin becomes clammy, the pulse is weak. The patient should be laid down with his head down and covered with something to keep him warm. Author: Likum A. Random interesting fact from the Great Encyclopedia: What are antibiotics? Antibiotics are medicines that are used to prevent and treat infectious diseases. "Anti" means "against" and "biotic" means "life". Antibiotics only affect certain life forms, the bacteria that cause disease. But antibiotics themselves are created on the basis of living organisms - bacteria, various compounds, larger plants. Antibiotic production began in 1928 when Sir Alexander Flemming discovered penicillin. His discovery was investigated by other scientists, which led to the search for new antibiotics. Soil samples around the world have been studied in search of microorganisms that would be able to produce substances that are applicable in the fight against infectious bacteria. As a result, today we have a lot of antibiotics, including penicillin, streptomycin, aeromycin, terramycin. Some antibiotics, in addition to affecting pathogenic bacteria, can be toxic to the body. How antibiotics stop the growth of bacteria is not yet entirely clear. Antibiotics are thought to prevent bacteria from getting the nutrients they need to grow. Each infection has its own antibiotic. Some patients have a particular sensitivity (allergy) to certain antibiotics. They can cause hives, asthma, or more serious illnesses. Sometimes antibiotic treatment takes a long period of time, and sometimes they are used prophylactically. With the advent of antibiotics, infections have become less likely to lead to death. Infectious diseases no longer pose a threat to human life.
