Real-time visual feedback during training improves laypersons’ CPR quality: a randomized controlled manikin study
ABSTRACT
Objective
The chances of surviving an out-of-hospital cardiac arrest depend on early
and high-quality cardiopulmonary resuscitation (CPR). Our aim is to verify
whether the use of feedback devices during laypersons' CPR training improves
chest compression quality.
Methods
Laypersons totalling 450 participating in Basic Life Support and Automated
External Defibrillation (BLS/AED) courses were randomly divided into three
groups: group No Feedback (NF) attended a course without any feedback, group
Short Feedback (SF) a course with 1-minute training with real-time visual
feedback, and group Long Feedback (LF) a course with 10-minute training with
real-time visual feedback. At the end of each course, we recorded 1 minute of
compression-only CPR. The primary end point was the difference in the
percentage of compressions performed with correct depth.
Results
There was a significant improvement in the percentage of compressions with
correct depth in the groups receiving feedback compared to the other (NF v. LF,
p=0.022; NF v. SF,
p=0.005). This improvement was also present in the
percentage of compressions with a complete chest recoil (71.7% in NF, 86.6% in
SF, and 88.8% in LF; p<0.001),
compressions with the correct hand position (93.2% in NF, 98.2% in SF, and
99.3% in LF; p<0.001), and in the Total
CPR Score (79.4% in NF, 90.2% in SF, and 92.5% in LF;
p<0.001). There were no significant
differences for all of the parameters between group SF and group LF.
Conclusions
Real-time visual feedback improves laypersons' CPR quality, and we suggest
its use in every BLS/AED course for laypersons because it can help achieve the
goals emphasized by the International Liaison Committee on Resuscitation
