摘要
Cardiopulmonary resuscitation is a simple and effective medical treatment for patients with sudden cardiac arrest. Most researches on CPR are animal experiments and human trials. Because there are many confounding factors present in experiments,conflicting conclusions are often drawn. In this paper,we followed the line of theoretical research on CPR. Then,we adapted previous CPR models,simulated rive CPR techniques using the adapted model,and compared their hemodynamics in the same test system. Through the comparison,the simulation results agree quite well with experimental data. The simulation results show that when external counter pulsation is applied during CPR,it may improve the cardiac output and increase the diastolic aortic pressure. Yet,external counter pulsation is not widely used during CPR. We think that this experiment deserves further research. Given the benefits of models and simulations,our adapted model may be a useful tool in CPR research.
