"The conventional wisdom is that about 30% of patients suffer fractures or breaks during CPR. However, a 2015 study published in Resuscitation suggested that this percentage is quite a bit higher. The study analyzed autopsy data from 2,148 patients who received CPR for non-trauma-related cardiac arrest, and the statistics were as follows:
* Skeletal chest injuries were found in 86% of men and 91% of women.
* 59% of the men and 79% of the women had sternum fractures.
* 77% of the men and 85% of the women had rib fractures."
Let's just say that it's really difficult not to break anything during CPR in general. Especially because the patient is often old and fragile. On young people, it's much easier.
