First, bleeding. Pressure bandaging to stop bleeding: fold sterilized gauze or clean towel and cloth into a pad slightly larger than the wound, cover the wound, and then tie it tightly with bandage or cloth belt. However, this method should not be used when a fracture or foreign body is suspected. Finger pressing to stop bleeding: According to the trend of the artery, pressing the artery near the heart of the bleeding wound with your fingers can temporarily stop bleeding, which is mostly used for arterial bleeding in the head, neck and limbs. ? Tourniquet to stop bleeding: Use rubber or cloth to bind the area with more muscles above the wound. The tightness should be such that the pulse of the distal artery cannot be felt and the wound can stop bleeding. If it is too loose, it won't stop bleeding. If it is too tight, it will affect blood circulation, damage nerves and cause limb necrosis.
Second, it's winter, so we should pay attention to gas poisoning. When there is a gas leak at home, cover your nose and mouth with a wet towel in time to avoid inhaling harmful gases. If you take the initiative to treat gas poisoning patients, you can first move the poisoned person to a ventilated place, unbutton his clothes to ensure his breathing is smooth, and then send the patient to the hospital.
Third, fracture. Because of falling or other circumstances, it may cause fractures. Don't move freely when you have a fracture. Call 120 emergency number in time and wait for hospital treatment. Don't pick up the injured patient on the road, which may cause greater secondary injury.
Conclusion: In order to cope with all kinds of accidents in life, it is very necessary to master some first aid knowledge.
