Nosebleed

The bleeding of the nose is caused by the rupture of blood vessels in the nasal cavity, and the blood vessels in the nose are very fragile, so nosebleeds are also a relatively common small accident.

First aid: The body leans forward slightly and uses your fingers to pinch the cartilage below the bridge of the nose for about 5-15 minutes.

If there are conditions, put a small ice bag on the bridge of the nose also has a rapid hemostasis effect.

Absolutely forbidden: The posture of lifting the head backwards will cause the nose to flow into the mouth. In the panic, some blood will be sucked into the lungs, which is neither safe nor hygienic.

Note: If the nosebleeds continue to flow for 20 minutes, the patient should immediately go to the hospital for help. If the number of nosebleeds is too frequent and there is no cause, or other symptoms such as headaches, tinnitus, decreased vision, and dizziness, then you must go to the hospital for treatment, because it may be that the brain has been shocked or severely damaged.

Burns are divided into three levels: one level of burns will cause redness and tingling of the skin; after the second stage burns, obvious blisters will be seen; third-level burns will cause the skin to break and blacken.

First-aid method: Once the burn has occurred, immediately place the burnt part under flowing water or use a cold towel to apply cold. If the burned area is large, the injured person should soak the whole body in a bathtub filled with cold water. Gauze or bandages can be loosely wrapped around the burn to protect the wound.

Absolutely forbidden: Ice can not be used to treat burns. Ice can damage damaged skin and cause wounds to deteriorate. Do not break the blisters or leave scars. Also don't smear antibiotic ointments or oils on the wounds. These sticky substances can easily contaminate dirt.

Note: Three-level burns, electric shocks, and chemical burns must go to the hospital for medical treatment. In addition, if the patient has a cough, tears in the eyes, or difficulty breathing, a professional doctor is needed. If the area is greater than the palm of the hand, the patient should also go to the hospital to see if the professional treatment can avoid scarring.
