Abstract：
Amplitude spectrum area (AMSA) is one of the most accurate predictors of defibrillation outcome. Details on functioning and use of the available technology to measure AMSA during cardiopulmonary resuscitation (CPR) in the real clinical scenario are described. During chest compression (CC) pauses for ventilations, AMSA is promptly calculated and values displayed through a modified defibrillator. In addition, real-time AMSA analysis has the additional promise to monitor CPR quality, being AMSA threshold values contingent on CC depth. Future larger studies employing this new technology are now needed to demonstrate the impact of AMSA on survival of cardiac arrest.

振幅谱面积(AMSA)是除颤结果最准确的预测因子之一。描述了在真实临床场景中在心肺复苏（CPR）期间测量AMSA的可用技术的功能和使用的详细信息。在胸部按压(CC)暂停通气期间,通过修改的除颤器迅速计算AMSA并显示值。此外,实时AMSA分析具有监测CPR质量的额外承诺，是取决于CC深度的AMSA阈值。现在需要采用这种新技术的未来更大的研究来证明AMSA对心脏骤停生存的影响。
