Abstract
Introduction: CPR training via cell phone application is an effective way to train laypersons in CPR. However, it is unclear whether using a combination of watching a brief video and live demonstration of CPR as well as receiving real time feedback via a cell phone application improves CPR quality, responsiveness and confidence. Objective: To determine if viewing a brief chest compression only (CCO) CPR video, watching a live demonstration and receiving real time feedback via the Celtic cell phone app. is an effective modality in training laypersons CCO-CPR leading to improved performance, responsiveness, and confidence. Methods: This was a prospective cohort control analysis from June 2014 till January 2016. Participants had little or no previous CPR training. Participants were consented and filled out an 8-question survey regarding baseline confidence in performing CPR. A CPR content quiz was answered to determine fluency in CPR. All participants then performed CPR on a mannequin while receiving real time feedback via the Celtic cell phone app. Finally they received formal “verbal” and “visual” training on CCO-CPR. Compression rate was categorized as very good if their compressions per minute (cpm) were >90, Ok if CPM was 80-89 and poor if CPM was <80. Compression depth categories were: Excellent: >2.0 inches, Good: 1.5-2.0 inches and Poor: <1.5 inches. Results: There were statistically significant improvements in percentage of participants (N=67) with very good compression rates (OR=49.1; 95% CI: 17.8, 135.0) and excellent compression depth (OR=26.5; 95% CI: 7.3, 96.1) from before to after the training and feedback using the Celtic app. Average score for confidence questions (difference=4.34; 95% CI: 3.67, 5.00); willingness to perform CPR in cardiac arrest patients (OR=6.83; 95% CI: 2.75, 17.01); and percent of content knowledge (difference=30.2; 95% CI: 25.0, 35.4) were significantly improved. Conclusions: CCO-CPR training via a combined program of watching a brief CCO video and live demonstration as well as getting real-time feedback via the Celtic cell phone application demonstrated statistically significant improvements in both target compression rate and depth as well as confidence in laypersons attempting to perform CCO-CPR.
