You must know the misunderstandings about first aid in daily life

　　Emergencies may occur at any time in life. When encountering emergencies, we need to provide correct first aid to the other person in time. In our lives, we know very little about first aid. We often get confused after meeting someone who needs first aid, and sometimes we even do the wrong first aid. These situations are very detrimental to those who need help, and we need to learn how to rush and avoid doing the wrong things.

　　What are the common misunderstandings about first aid in daily life?

　　1. Randomly pinch "people"”

　　“"Renzhong point" is located at the midpoint of the nasolabial fold, but many people are not very clear about the exact location of "Renzhong" and pinch it in a hurry, which cannot provide first aid. Wen Xinhua said that the correct approach is to first determine whether the comatose person is conscious. You can wake up the comatose person by shouting, slapping, or stimulating pain. If you find that the comatose person has no pulse or heartbeat, you should call 120 emergency hotline in time.

　　2. Dare not perform CPR

　　In the event of drowning or cardiac arrest, people around you should immediately perform cardiopulmonary resuscitation, untie the patient's collar, keep breathing unobstructed, overlap your hands, interlock the crosses, and press vertically downward at the midpoint of the two connecting lines, with a depth of at least 5 cm, and a compression frequency of 100-120 times/minute. For every 30 chest compressions, perform 2 artificial respirations. Modern medicine shows that performing cardiopulmonary resuscitation within 4-6 minutes of cardiac arrest may save the patient's life.

　　3. Recklessly moving the injured in the car accident

　　After a car accident, do not move the injured person at will. If the injured person only has limb trauma, he should be bandaged to stop the bleeding and fix the injured limb in time. If bleeding from the ear and nose of the injured person is found, it may be intracranial bleeding. At this time, if the bleeding cannot be stopped or the affected area is blocked, the bleeding site should be pointed downward to allow the blood to flow out to avoid increasing intracranial pressure or intracranial infection. If the injured person has a spinal cord injury, remember not to move around, call the emergency number as soon as possible, and wait for professional emergency personnel to arrive.

　　4. Food poisoning blindly induces vomiting

　　Do not blindly induce vomiting when you accidentally eat poisonous liquid or have food poisoning. When the patient is conscious, he or she can ingest 300-500 ml of water and hold it against the base of the tongue to stimulate the pharynx and promote vomiting of toxic substances. When the patient loses consciousness, gastric lavage cannot be administered orally, otherwise it may cause suffocation and the patient should be sent to the hospital immediately. After accidentally ingesting strongly acidic and alkaline liquids, you must not induce vomiting, otherwise the poisonous liquid will rise up and return to the esophagus, causing secondary damage to the esophageal mucosa and throat mucosa.

　　5. Misjudgment of sudden myocardial infarction

　　Myocardial infarction is related to many diseases. Once it occurs, the cause needs to be determined first. In some cases, aspirin can be chewed to prevent thrombosis. However, if there is a history of cerebral hemorrhage, gastrointestinal bleeding, or dissecting aneurysm, aspirin cannot be used and should be sent to the hospital for emergency treatment immediately.

　　It is very important to learn some first aid methods so that you can help others or save yourself at critical moments. Learning first aid can not only protect yourself, but also help others.
