Elderly people choking on food can be dealt with by patting, hand-picking, drinking vinegar and Heimlich’s first aid. 1. Patting method: Pat the back of the choking old man rhythmically with your hand with certain strength, which will help the old man cough out the choking material, and you should pay attention to the moderate strength. 2. Hand-picking method: If you can see what kind of food is choking in the throat of the elderly, and the location of the choking object is shallow, you can take the method of picking out the choking object with your hand directly, but you need to pay attention to not picking the elderly’s oral cavity and pharynx. 3. Drinking vinegar: Generally, it is only used for those who are choked by fishbone, and the vinegar can soften the fishbone, which is convenient to be swallowed or taken out. 4. Heimlich’s first aid method: hold the old man’s abdomen from behind, then make a fist with one hand and press the part between the navel and ribs of the old man with the center of the fist, stretch the other hand and press it on the top of the fist, and finally squeeze both hands upward and inward quickly, and then repeat the process until the old man vomits out the choking material. If the above methods do not work or are not effective, the elderly can go to the hospital for examination and appropriate treatment.
