Complications of CPR include skeletal injuries, espe-cially rib fractures, visceral injuries, airway injuries, and skin and integument damage (skin, teeth, lips). Less than 0.5% of the complications are considered life-threatening. These include injuries to the heart and the great vessels. However, a significant number of complications could be expected to require therapy and prolong the hospitalization. These include rib and sternal fractures, myocardial and pul-monary contusions, pneumothorax, blood in the pericar-dial sac, tracheal and laryngeal injuries, liver and spleen ruptures, and gastric perforation and dilatation.
