Abstract 12022: LinkCPR Improves the Quality of Hands-only CPR Performed by Laypersons Following the 2015 AHA Guidelines
Introduction: The AHA 2015 Resuscitation Guidelines changed the guidelines for chest compression (CC) rate and depth. Manikin studies have demonstrated that feedback/prompt systems improve the quality of CPR. On the other hand, LinkCPR (SunLife, China) is a newly designed feedback/promt device that can provide the real-time CC depth, rate, chest recoil feedback and data review. In this study, we investigated the effects of LinkCPR on the quality of CCs during hands-only CPR performed by laypersons based on the 2015 AHA guidelines.
Hypothesis: LinkCPR improves the quality of CCs performed by laypersons.
Methods: Eighty laypersons were assigned randomly to perform CPR on manikins with (Link group) or without (C group) LinkCPR. Participants underwent manual CPR training and took a written basic life support examination; they were then required to perform two min of hands-only CPR. The quality of CPR was quantified as the percentage of correct CCs (appropriate depth, rate, and complete recoil) each minute.
Results: Thirty-nine participants in the Link group and 37 participants in the C group completed the study. There were no significant differences in gender and body mass index between groups. Reductions in the mean depth of CCs and proportion of correct CCs after the first minute of CPR were observed in both groups. However, significantly better performance was achieved by rescuers in the Link group when compared with those in C group during each of the 2 minute CPR periods (Table).
Conclusion: LinkCPR improves the quality of hands-only CPR performed by laypersons following the standards of the 2015 AHA guidelines.
