ObjectivesCardiopulmonary resuscitation (CPR), which is used in cases of life-threatening cardiopulmonary arrest, is a physically exhausting procedure. Adding to that, sometimes, even before performing CPR, interventions to rescue the injured person from a challenging environment have caused significant fatigue. In this study, taking a novel research approach, we generated a scenario of fatigue during a rescue from earthquake debris and aimed to measure the effect of that fatigue on the quality of CPR performed by paramedics.MethodsThe research followed an experimental design with 2 groups (experimental/control) and 2 measurements (pretest/post-test). The study population was selected using power analysis. The sample, consisting of 84 paramedic students, was randomly divided into 42 control and 42 experimental participants. Current American Heart Association (AHA 2020) and European Resuscitation Council (ERC 2021) guidelines were strictly followed when performing CPR. In order to assess the accuracy of CPR, a General Doctor GD-CPR200S-A (2010 standard) simulator was utilized. The participants were fatigued by practicing the process of extracting and transporting earthquake victims from rubble. A personal information form with 20 questions and a CPR measurement form were used to obtain the data.ResultsIn the analysis performed to measure the differences between the CPR indicators for the control and experimental groups in the post-test and pretest, the difference in compression (control: 6.5 ± 50.1 and experimental: -10.3 ± 46.0) was not significant. Meanwhile, we found that the difference in ventilation (control: 0.3 ± 5.4 vs. experiment: 8.1 ± 4.6) and the difference in CPR completion times (control: 0.2 ± 1.2 vs. experiment: -0.7 ± 0.7) between the post-test and pretest were significant.ConclusionsThere was no significant difference in correct compressions between the control and experimental groups, but there was a significant difference in ventilation and CPR completion times. For this reason, it is recommended to focus on the effect of fatigue on CPR quality, especially on the ventilation process. It is also recommended to include fatigue scenarios in CPR trainings.
