What to do when CPR presses broken ribs, especially for the elderly, due to their osteoporosis or hardness of bones, when performing emergency CPR, it is easy for rib fracture to occur, which is unavoidable and not subjectively caused by the doctor, which is a problem that cannot be easily avoided in CPR. For single or multiple rib fractures, if there is no problem of hemothorax or pneumothorax, surgery is usually not needed, but merely the use of external fixation with a chest strap, external plasters, oral blood circulation and analgesic medication and other treatments, waiting for its natural healing. If more rib fractures produce thoracic collapse, affect breathing movement or produce serious complications such as hemothorax or pneumothorax, surgical treatment is usually adopted.
