Basic family first aid knowledge（1）
The first one is foreign matter entering the eye.
First aid method: First, blink vigorously and frequently, and wash out foreign objects with tears. If it doesn’t work, pinch your eyelids and rinse your eyes under the tap. Be sure to remove contact lenses. If the corrosive liquid splashes into the eyes, you must go to the hospital for diagnosis and treatment immediately; if the eyes are still uncomfortable after self-treatment, burning, edema, or blurred vision, you also need to ask a doctor to treat with professional equipment. Act recklessly.
The second is a sprain.
First aid method: within 24 hours of the sprain, try to apply cold compresses with an ice pack every hour, every half an hour. Wrap the injured area with an elastic compression bandage and elevate the injured area. After 24 hours, the affected area was changed to hot compress to promote blood circulation in the injured area. If after several days of self-treatment and rest, the affected area is still painful and inconvenient to move, it may be a fracture, muscle strain or ligament rupture, and you need to go to the hospital immediately.
The third is nosebleeds.
First aid: Lean forward slightly and pinch the cartilage under the bridge of the nose with your fingers for about 5-15 minutes. In addition, putting a small ice pack on the bridge of the nose can also quickly stop bleeding. If the nosebleed continues for 20 minutes and still cannot be stopped, the patient should immediately go to the hospital for help. If the nosebleeds are too frequent and have no cause, or are accompanied by headaches, tinnitus, decreased vision, dizziness and other symptoms, then be sure to go to the hospital for treatment, because this may be due to concussions or severe brain damage.
The fourth one is burns.
First aid method: Once a scald occurs, immediately rinse the scalded part under running water or apply a cold towel with a cold towel. If the burned area is large, the injured person should soak the whole body in a bathtub filled with cold water. You can wrap gauze or bandage loosely around the burn to protect the wound. You must go to the hospital for third-degree burns, electric shock burns, and chemical burns. In addition, if the patient has a cough, watery eyes or difficulty breathing, he needs the help of a professional doctor. If the area of the second-level scald is larger than the palm of the hand, the patient should also go to the hospital. Professional treatment can avoid scars.
