中文摘要：

为实现新型复苏术——辅以增强型体外反搏和吸气阻力阀的主动按压放松心肺复苏术（AEI—CPR）的数字化，用计算机仿真模型模拟了人体在正常情况、心脏骤停以及采取新型复苏术后的血流动力学效果，并将标准复苏术（S—CPR）、主动按压复苏术（ACD—CPR）、以及带有增强型体外反搏的标准复苏术（SE．CPR）和新型复苏术AEI—CPR等的仿真结果进行了比较．结果表明：S—CPR产生的前向血流（FF）为1．1L／min，冠脉灌注压（CPP）为30．2mmHg；ACD—CPR产生的FF为1．2L／min，CPP为31．3mmHg；SE—CPR产生的FF为5．2L／min，CPP为57．4mmHg：AEI．CPR产生的FF为5．6L／min，CPP为57．6mmHg；带有增强型体外反搏的复苏术SE—CPR和AEI—CPR可显著提高前向血流，AEI—CPR的血流动力学效果最好．

英文摘要：

In order to digitalize a new cardiopulmonary resuscitation （CPR） called active compression-decompression CPR with enhanced external counterpulsation and inspiratory impedance threshold valve （AEI-CPR） , the hemodynamics of human body in the conditions of normal circulation, cardiac arrest and CPR were respectively simulated with computer model, and several CPR techniques, such as the standard CPR （S-CPR） , the active compres- sion-decompression CPR （ACD-CPR） , the standard CPR with enhanced external counterpulsation （SE-CPR） , and the AEI-CPR, were compared via simulation. The results indicate that （1） S-CPR generates a forward flow （FF） of 1.1 L/rain and a coronary perfusion pressure （CPP） of 30.2 mmHg, while those generated by ACD-CPR, SE- CPR and AEI-CPR are respectively 1.2 L/rain and 31.3 mmHg, 5.2 L/rain and 57.4 mmHg, and 5.6 L/rain and 57.6 mmHg ; （2） both the SE-CPR and the AEI-CPR greatly improve the forward flow ; and （3） AEI-CPR is of the best hemodynamic effect.
