根据美国心脏协会(AHA)2010年指南，在心肺复苏(CPR)中，胸部按压胸骨下半部分。这些还没有研究确定单个胸部按压应用的确切位置。我们开发了一种橡胶动力柔性电容式传感器，可以实时测量胸部按压的实际压力点。在这里，我们检查了救护人员在使用人体模型进行心肺复苏时胸部按压的压力点。我们包括179名救护车人员。胸部按压2min。使用弹性压力传感器(ShInnosukekun(TM))监测压力位置，并分析胸部按压的质量。在救护人员中，58人(32.4%)按压中心，121人(67.6%)按压胸外。其中许多按压在中心外；8、7、41和90分别按压在尾侧、左侧、右侧和颅侧。平均压缩比为108.6次/分，平均反冲次数为0.089次/分，平均深度为4.50厘米，平均占空比为48.27%。许多救护车工作人员并没有明确地按压胸骨下半部分。这一新设备有可能在训练期间或临床实践中提高CPR的质量。
In chest compression for cardiopulmonary resuscitation (CPR), the lower half of the sternum is pressed according to the American Heart Association (AHA) guidelines 2010. These have been no studies which identify the exact location of the applied by individual chest compressions. We developed a rubber power-flexible capacitive sensor that could measure the actual pressure point of chest compression in real time. Here, we examined the pressure point of chest compression by ambulance crews during CPR using a mannequin. We included 179 ambulance crews. Chest compression was performed for 2 min. The pressure position was monitored, and the quality of chest compression was analyzed by using a flexible pressure sensor (Shinnosukekun (TM)). Of the ambulance crews, 58 (32.4 %) pressed the center and 121 (67.6 %) pressed outside the proper area of chest compression. Many of them pressed outside the center; 8, 7, 41, and 90 pressed on the caudal, left, right, and cranial side, respectively. Average compression rate, average recoil, average depth, and average duty cycle were 108.6 counts per minute, 0.089, 4.5 cm, and 48.27 %, respectively. Many of the ambulance crews did not press on the sternal lower half definitely. This new device has the potential to improve the quality of CPR during training or in clinical practice.
