Abstract
OBJECTIVE: To evaluate the quality of cardiopulmonary resuscitation (CPR) by lay people when guided by a mobile phone application with real-time feedback, with the comparison of three different mobile phone applications (APPs). DESIGN: A cross-sectional quasi-experimental study was carried out. PARTICIPANTS: A sample of 113 nursing students participated in the study. INTERVENTIONS: Three hands-only CPR tests with continuous compressions were performed: (i)without external help; (ii)with the mobile phone turned off; and (iii)guided by APP. Three different APPs were randomly assigned (Pocket CPR®, CPR Pro®> and Massage cardiaque et DSA®). The mannequin Laerdal Resusci Anne QCPR (Stavanger, Norway) 2.0.0.14 software was used. VARIABLES OF PRIMARY INTEREST: APPs used. Demographic variables characterizing the study sample. INDEPENDENT VARIABLES: mean depth, mean rate, percentage of correct hand positioning, percentage of compressions with correct re-expansion, percentage of compressions with correct depth, percentage of compressions at the correct rate, and overall quality of CPR. RESULTS: Overall CPR quality was 33.3% ± 32.7 using Pocket CPR, 10.9% ± 22.72% using CPR Pro and 7.8% ± 9.2 using Massage cardiaque et DSA. None of the APPs produced a statistically significant improvement. The percentage of time that the resuscitator managed to maintain a correct compression rate improved when using all three APPs. CONCLUSIONS: Cardiopulmonary resuscitation guided by phone APPs did not improve the overall quality of compressions during resuscitation, though it improved the percentage of compressions performed at the correct rate.
