Quality of bystander cardiopulmonary resuscitation - Can a smartphone bring about a revolution?

Abstract

In order to improve the life saving rate of patients with outof- hospital cardiac arrest, which occurs in approximately 70,000 people in Japan each year, an increased implementation rate of cardiopulmonary resuscitation (CPR) by the general public and improvement of the quality of bystander CPR are essential.1,2 However, it is not easy for non-health practitioners to master high-quality CPR skills, although various methods have been investigated, because the CPR itself is something out of the ordinary and involves partially invasive procedures.
