Abstract:
The rates of recovery of spontaneous circulation, admission survival, and discharge survival of out-of-hospital cardiac arrest (OHCA) patients in China are much lower than the world and Asian averages, and the data on the survival of in-hospital cardiac arrest (IHCA) patients are also less favorable. The variable quality of cardiopulmonary resuscitation (CPR) and the low percentage of bystander CPR participation are the main reasons for these phenomena. Real-time feedback devices are an effective strategy to address these issues and have been recommended for use in several guidelines. However, the existing CPR feedback devices have the problems of being inconvenient to operate and expensive to popularize. Therefore, members of the CPR training team of Loudi Central Hospital designed a CPR real-time feedback APP device, which has been granted the right of National Invention Patent of China (patent number: ZL 2021 1 1118500.1). The device consists of a feedback device and a mobile device (there are two versions: healthcare professionals and non-healthcare professionals). The feedback device consists of a pressing plate and a soft rubber plate. The inner side of the soft rubber plate is covered with sensor monitoring points. On each sensor monitoring point, there are micro pressure sensors and micro acceleration sensors. When performing chest compressions, the sensors will transmit the relevant data to the cell phone feedback APP. By sampling and analyzing the data and building a three-dimensional dynamic model, the feedback APP accurately judges the effect of chest compressions based on factors such as the strength of the compressions, the frequency of the compressions and the depth of the compressions, corrects and provides voice guidance for the subsequent CPR process in real time, guides the rescuers to follow the standardized procedures for rescue, and improves the survival rate and neurological recovery of the CPR patients. The device improves CPR with exact effect, real-time accuracy, simple operation, easy to promote, and applicable to all populations. It has good clinical application and socialization popularization value, and can be equipped in medical institutions and public places.
