Cardiopulmonary resuscitation (CPR) is the principal means for combating death caused by cardiac arrest in the prehospital setting. Adequate evaluation of CPR standards, however, requires exacting replication of both positive pressure ventilation and cardiac compression protocols over sufficient time periods to measure effects on arterial blood gases, hemodynamics, and intrapulmonary shunting. The programmable cardiopulmonary resuscitator studied provides for such highly controlled CPR protocols. It is developed from a cardiopulmonary resuscitator that has been adapted to accommodate a universal programmable timer. The programmable cardiopulmonary resuscitator permits independent changes in rate, duration, and sequence of both positive pressure ventilation and cardiac compression. Hence, it makes possible the simulation of one-rescuer and two-rescuer CPR standards, as well as the investigation of alternative CPR techniques.
心肺复苏术（CPR）是在院前环境中对抗心脏骤停导致死亡的主要手段。然而，对心肺复苏标准进行充分评估需要在足够长的时间段内精确复制正压通气和心脏按压方案，以测量对动脉血气、血流动力学和肺内分流的影响。所研究的可编程心肺复苏器可实现这种高度可控的心肺复苏方案。它是由一种已适配通用可编程定时器的心肺复苏器发展而来的。该可编程心肺复苏器允许独立改变正压通气和心脏按压的速率、持续时间和顺序。因此，它使得模拟单人施救和双人施救的心肺复苏标准以及研究替代性心肺复苏技术成为可能。
