What bones are most likely to be fractured when chest compressions done improperly during CPR?

During cardiopulmonary resuscitation (CPR), if chest compressions are done incorrectly, there is a risk of fracturing certain bones in the chest area. The bones that are most likely to be fractured during CPR are:

1. Ribs: The ribs are the long curved bones that form the rib cage. Incorrect hand placement or excessive force during CPR can cause ribs to fracture.

2. Sternum: The sternum, also known as the breastbone, is the flat bone in the center of the chest. It can be fractured if too much force is applied during chest compressions.

3. Clavicle: Also known as the collarbone, the clavicle is the bone that connects the shoulder blade to the breastbone. It is vulnerable to fracture if the rescuer's hands are placed too high on the chest during chest compressions.

The correct technique for chest compressions during CPR involves placing the heel of one hand on the center of the person's chest and the other hand on top, interlocking the fingers. The chest should be compressed down about 2 inches at a rate of approximately 100 to 120 compressions per minute.

It's important for individuals performing CPR to receive proper training and maintain current knowledge about CPR techniques to minimize the risk of injuries and effectively provide lifesaving support during cardiac emergencies.
