The effect of a cellular-phone video demonstration to improve the quality of dispatcher-assisted chest compression-only cardiopulmonary resuscitation as compared with audio coaching

Efficacy of metronome sound guidance via a phone speaker during dispatcher-assisted compression-only cardiopulmonary resuscitation by an untrained layperson: a randomised controlled simulation study using a manikin

“…Recently, a simulation trial showed that the interactive video instruction of a dispatcher using video cell phones can improve the quality of chest compressions compared with verbal dispatcher instructions in the setting of COCPR by untrained laypersons 32. Another similar simulation trial showed that a CPR video clip stored in cellular phones can improve the performance of chest compressions during COCPR 15. Visual feedback may help to overcome the handicaps of verbal instruction, but it may have several limitations in the real world.…”

“…Visual feedback may help to overcome the handicaps of verbal instruction, but it may have several limitations in the real world. Video instruction can delay the initiation of chest compression, and watching the video may be difficult while performing chest compressions 15 32. Most of all, a phone with video function may not be available to laypersons in many situations.…”

Use of Mobile Devices, Social Media, and Crowdsourcing as Digital Strategies to Improve Emergency Cardiovascular Care

“…Several simulation studies have suggested that the addition of video to the interaction between bystander and call taker can improve CPR quality. [51][52][53][54] Future research needs to determine whether video augmentation of the interaction between dispatchers and bystanders is feasible and translates into improved CPR quality and survival for patients with OHCA.…”

iPhone Apps for Cardiopulmonary Resuscitation (CPR): A Content Analysis

“…Studies have shown that lay rescuer CPR is improved by the use of smartphone technology and that apps are effective tools for improved retention of CPR knowledge in trained rescuers. Recent trends in CPR instruction research show that video instructions as well as promptings and feedback via smartphone technology result in improved delivery of CPR by both lay and trained rescuers (Ramirez et al 1977;Lee et al 2011;Merchant et al 2010;Yang et al 2008). Another study focused on simpler methods of training the lay person in CPR using video-based self-instruction (Yeung et al 2009).…”
