Modeling and simulation of hemodynamic effects during different cardiopulmonary resuscitation (CPR) technologies

Cardiopulmonary Resuscitation (CPR) is a simple and effective medical treatment for sudden cardiac arrest patients. Because of those existing interferences in the experiments, most of the animal experiments and the CPRs in vivo studies get contradictory conclusions. In this report, according to the current theories of CPR, we got a CPR model; simulated various CPR technologies, and compared their hemodynamic variables. Compared the simulation results and animal experimental data, this report showed that when the External counterpulsation technique applied in CPR, the cardiac output, as well as the diastolic and the aortic pressure would be improved, which was consistent with the results of animal experiments.
