A Study on the Effectiveness of Video Call Dispatcher-Assisted Cardiopulmonary Resuscitation in Enhancing the Quality of Cardiopulmonary Resuscitation Among Laymen Bystanders in Malaysia

Abstract

Aim: Technology has enabled the utilization of dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) through mobile video call for layman bystanders as opposed to the conventional audio call. This study aimed to examine the effects of medical guidance through a video call on cardiopulmonary resuscitation (CPR) quality during the management of cardiac arrest. Materials and Methods: A quasi-experimental study was conducted on 102 participants. These participants were divided into two groups: laymen who received CPR instructions through dispatcher-assisted video call (n=51) and healthcare personnel (n=51) who did not receive any assistance. The compression rate and depth, compression fraction, chest recoil, and hand positioning were compared between the groups. Results: Laymen who received video call DA-CPR performed better than the healthcare personnel in adhering to the recommended compression rate (109.7 min-1 vs 126.7 min-1, p
