Fine sand enters the eyes. If sand enters the eyes, do not rub it with your hands. Blink your eyes a few more times to let the tears wash away the sand. You can also ask someone to open the upper eyelid and gently wipe off the sand with a cotton ball or a clean soft cloth or handkerchief.
The tricks that must be known are very useful at critical moments!
Fish bones stuck in the throat. If fish bones or chicken bones get stuck in the throat, do not swallow hard or dig with your hands. If the fish bone has just stabbed someone, and some of them are outside, please use tweezers to pull it out steadily and quickly. If the position of the stuck is too deep, you should go to the hospital for treatment immediately.
The fracture occurred. If you have a fracture, don't fiddle with it or connect the bones at will. If there is a fracture of the clavicle, first use a bandage to cover the arm and do not move it; if there is a fracture in the pelvic cavity or chest and waist, the patient should be gently lifted up and placed on a hard stretcher to minimize vibration during the transfer; if there is a fracture of the limbs, materials can be taken locally, such as temporary fixation with rubber shoes, cloth shoes, thicker branches or other things that can be used to fix, and then sent to the hospital for treatment.
spasmodic twitch. If spastic convulsions occur, the head should be sideways to remove secretions from the mouth and nose, wrap a soft cloth with chopsticks or wooden pieces, and stuff it between the upper and lower teeth to avoid biting the tongue. If it is spastic convulsions caused by high fever, use a cold towel to apply wet on the head and then rushed to the hospital.
Suddenly unconscious. In case of coma, do not panic. Some secretions or foreign objects in the nasopharynx of the coma should be removed, keep the respiratory tract unobstructed, and lie on the side to prevent sputum from inhaling into the lungs and causing pneumonia. Put your head flat and send it to the hospital for treatment.
Gas poisoning. In case of gas poisoning, please move the poisoned person out of the site immediately, go to a ventilated place, unbutton your clothes, and send it to the hospital for emergency treatment.
Sudden heart disease. If someone suddenly has a heart attack, before the ambulance arrives, the patient should be placed in a sitting or half-lying position and untie tight clothes, do not move the patient or give him a irritating beverage.
The bleeding continues. If bleeding persists in traffic or other accidents, you can use your hands, tissues, shirts, and gauze to directly press the bleeding site to jamm the artery blood vessels to stop the bleeding. If there is a foreign object in the wound, such as glass, you can use your hands to press the area near the bleeding.
