人体胸廓心肺复苏胸外按压力学模型及其模拟研究进展

Advances in Researches on Throax Mechanical Modeling and Simulation during Cardiopulmonary Resuscitation

心肺复苏(Cardiopulmonary resuscitation,CPR)是对心脏骤停患者实施急救的重要技术,国内外对该技术的机制、操作规范、新型的CPR仪器等进行了一系列研究。本文重点综述了CPR胸外循环按压时的人体胸廓力学特性研究以及目前CPR模拟人对按压力—胸骨位移(Force-sternal displacement)关系的模拟。已经建立的模型,显示胸廓按压力—胸骨位移关系成滞回曲线。目前的CPR模拟人采用弹簧结构进行的模拟过于简化,有必要进行相关的研究,使得模拟人与人体实际情况更加接近。

Cardiopulmonary resuscitation （CPR} is vital for cardio arrest victims; in this field, researches have been aiming at its mechanism, operation guidelines, new CPR machines and so on. This paper summarized the studies on the mechanical characteristics of the thorax under CPR, and on the simulation work of sternal-displacement relationship in CPR manikins. The data from modeling work showed that the thorax＇s sternal-displacement relationship could be graphically represented by a hysteresis curve. As the actual CPR manikins＇ mechanical structures of the thorax are too simplified, it is necessary to do the work of improvement.
