Abstract: Cardiopulmonary resuscitation (CPR) is a first aid technique that too often ignores the bone physiology of the patient. Factors affecting the risk of performing a CPR were investigated using a full human ribcage FE-model, representing an average human adult. Two response variables of the FE-model were evaluated: the displacement of the sternum and the equivalent Von Mises stress in the ribcage. Based on the displacement of the sternum is possible to determine when the CPR is appropriate, according to the guidelines proposed by the American Heart Association (AHA). The ribcage FE-model included three tissues: cortical and trabecular bone tissue and cartilaginous tissue. First, the usual range of variation of the elastoplastic properties of these materials was examined. Secondly, the model was subjected to a sensitivity analysis to evaluate the influence of these elastoplastic properties on CPR. The study revealed that the elastic properties of the cartilage tissue are decisive to perform an adequate CPR. Likewise, the properties of the trabecular tissue have a significant influence on CPR, with the properties of the cortical being less important. The results suggest that the change in mechanical properties of these tissues with age and bone disease should be considered when performing CPR.
