Abstract

The CPR guidelines emphasize the delivery of effective chest compressions but do not address the effects of chest compressions on CPR providers. This study determined the effects of chest compressions on healthy adult firefighters' symptoms, hemodynamics, and electrocardiography after performing multiple cycles of CPR. Healthy adult firefighters were trained in CPR and performed CPR on mannequins. The provider vital signs, electrocardiography, and fatigue scores were determined immediately before CPR, after 5cycles of CPR, and after 10 cycles of CPR. In addition, the presence of clinical symptoms among the providers was determined after CPR; 39 firefighters participated in the study. Their mean age was $35.54{\pm}10.26years$. Many providers developed fatigue, shortness of breath, and dizziness. Significant changes in heart rate (p=0.000), respiratory rate (p=0.010), end-tidal CO2(p=0.000), O2 saturation(p=0.000), and pulse pressure (p=0.000) were observed after both 5 and 10 cycles of CPR. One participant developed sinus dysrhythmia and premature ventricular contractions after 10 cycles of CPR. The delivery of chest compression results in fatigue and hemodynamic alterations in many young healthy adults after performing 5 or 10 cycles of CPR. The CPR guidelines and education should take into consideration the effects of chest compressions on CPR providers.
