The Computer Model in View of Hemodynamic Effects of Electro Ventilation Double Pump CPR
Electro ventilation double pump cardiopulmonary resuscitation (EDCPR) was a cardiopulmonary resuscitation (CPR) technique that chest compression was coupled with Lower limbs compression to improve the aortic pressure and myocardial perfusion pressure.The paper was to study the hemodynamic effects during human cardiac arrest and find the optimum value of lower limbs compression pressure (LLCP) when chest compression pressure was definite.First the computer model of human circulation was developed,second the effects of EDCPR to the model were performed,third the comression schemes were performed by computer simulation and the optimum value was found.The results were that EDCPR got the good hemodynamic effects.The proper value of the LLCP was found.And they were in accordance with the results of parallel animal experiments and the data published before.The developed model can successfully describe the effects of different CPR techniques and different compression schemes to the circulation system during cardiac arrest.
