When performing cardiopulmonary resuscitation, chest compressions should be performed, and the most easily caused complications during cardiac compressions are generally due to improper operation of the compressions, rib fractures occur, and the broken ends of the fractures can puncture the heart, lungs, trachea, and abdominal organs, or directly cause organs to rupture, which can lead to pneumothorax, hemothorax, or rupture of the liver, spleen, stomach, and diaphragm, and fat embolism. Therefore, when performing cardiopulmonary resuscitation thoracic cardiac compression, it is necessary to master the correct and effective compression technique, the compression should be smooth, the force should be even, and the compression should be done in a regular manner, and all the compressions should be relaxed after each compression, so that the chest can return to its normal position and the sternum is not subjected to any pressure, which can effectively reduce the occurrence of the above complications.
