Rib Fracture - A Rare Complication of CPR Compressions

Rib fracture is the most common complication (19.7%–73.7%), followed by sternal fracture (14.0%). (1), (3)
Although most of these injuries are not life-threatening, severe injuries have often been found in 2.0% of cases. (1)
Chest compressions during cardiopulmonary resuscitation (CPR) can be traumatic to patients. (1)
Sternal (breastbone) fractures occur in 1 of 5 resuscitation attempts, and costal (rib) fractures occur in 1 of 3. (2)
Two-thirds of patients with costal fractures have 3 or more fractures in adjacent ribs. (2)
