[Design and application of a portable cardiopulmonary resuscitation protection device].

Zhonghua Wei Zhong Bing Ji Jiu Yi Xue 2022 May;34(5):542-544

Department of Emergency And Rescue Medicine, Xuzhou Medical University, Xuzhou 221004, Jiangsu, China.

Standardized cardiopulmonary resuscitation (CPR) of patients prior to the arrival of emergency medical services can significantly improve survival rate after out-of-hospital cardiac arrest (OHCA). According to statistics, about 40% to 85% of CPR led to chest fractures, making bystanders alarm, and reducing the willingness of rescuing by CPR. Therefore, there is an urgent need to develop a CPR protection device that is convenient for placing in public places outside the hospital and conforms to the operation habit of freehand CPR.
