Purpose of the study
High-quality cardiopulmonary resuscitation (CPR) improves the cardiopulmonary arrest (CA) prognosis and requires continuous training (1). Feedback devices have been developed to improve chest compressions but have had little impact due to their low efficacy (2-3).
The purpose of the study is to determine the efficacy of Face the CPR App designed by our group on improving high-quality CPR and adherence to Advanced Cardiovascular Life Support (ACLS) guidelines during simulationbased learning on ACLS courses.
Materials and methods
30 subjects who were trained in ACLS were recruited. 28 clinical cases of CA were performed. The group was randomly assigned (App or Control).
We registered the quality of chest compressions using the Laerdal Resusci Anne QCPR® and the adherence to the ACLS guidelines as well as secondary variables applying a survey.
CONTROL APP P Primary variables Median (IQR)
Percentage of compressions between 100-120 BPM(%). 71(4,5) 94(3) <0,01
Percentage of compressions with correct depht(%). 76(21) 88(13) 0,6
Time to diagnose/treat CA rhythm after first cycle(seconds). 96(17,5) 120(0) 0,04
Time to diagnose/treat CA rhythm after second cycle(seconds). 114(30) 120(0) 0,036
Adrenaline administration delay (first cycle)(seconds). 30,5(9) 0(0) <0,01
Adrenaline administration delay (second cycle)(seconds). 6(9) 0(0) 0,571
Adequate therapeutic approach(%). 50(50) 100(0) 0,03
Secondary variables Mean (CI) Leader communication(0-100) 70,4(58-82) 84,6( 78,6-90,6) 0,026
Self assessment of performed CPR (0-100)
79,1 (73,3-84,9) 0,021
Our APP could be a useful tool on ACLS improving not only the percentage of correct rate of chest compressions and adherence to the ACLS guidelines but also the leader communication during simulation-based cases.
