If you are choked.

 This is a happening on the meal time, when you are laughing, talking, fast eating, piece of meal enters in throat, closing breath ways. A good here if you can be coughing and remove this piece. If piece if big, this is a not ability to do,thus here needing first aid, if not,you are getting asphyxia, and you can to dead.

And do not beat  by spine, piece can enter deeper in trachea, thus remove his harder. And for help right here use method Heimlich, and every need to use his, and his simple, and in different from beating, helping remove piece by air stream.

As stand behind a patient, catch with both hands on the level top belly side and incline to the front.One hand squeeze in fist, put his on middle between navel and xiphoid appendix for breast.Catch his an other hand and faster press on the belly in direction for inside and up. Repeat,till piece fly out. This is not hard and all is ability to do. And if you are choked, and staying alone ,thus you cannot self-help , here is one variant I found. But am not used his. Am trained, but this case not happened. If this is happening, thus am ready. Not panic,  visit to table, or chair s wall, bed, any other top with edge. Keep with hands, faster low on edge with belly top. And Task here for a faster shortening diaphragm and push out by air  stream a piece .Not think about aches, bruises,they will leave, but if you cannot remove obstacles is on the air way, you can dead. And still method, I saw video. Stay on knees, support with hands in floor, palms are slightly front to a shoulder. Legs are back, a position ,like you are going doing push up. After this a faster relax hands,like  fallen with breast on the floor. A better something put soft on the floor, against injury. And on the process  landing a breast cell squeezing, lung too, and air from mouth  breaking out a very strong  jet. Am too tried, such current is must to push out a foreign body.
