Background Cardiopulmonary resuscitation (CPR) is a lifesaving skill performed during the cardiac arrest. Various factors of rescuer affect CPR quality, and rescuers physical fitness is one among the important factors needs to be explored for improved CPR quality. This study aimed to assess the physical activity (PA) levels of the health care providers (HCPs) who were trained in basic life support (BLS) and its relationship on chest compression duration, hemodynamic parameters, and fatigue levels of the rescuers. Materials and methods A single-center, cross-sectional study was conducted on 48 HCPs who were trained in BLS within one year. Eligible participants were contacted by email, and the responders’ level of PA was determined using the global physical activity questionnaire (GPAQ). The participants were recruited for chest compression-only cardiac arrest scenarios. Each subject performed continuous chest compression on the manikin until they perceived maximum fatigue. Heart rate (HR), blood pressure (BP), oxygen saturation (SpO 2 ), and fatigue level were assessed at baseline, immediately after and following two minutes of cessation of chest compressions. The total duration of chest compression was also documented. Results Most participants (24, 50%) reported high levels of PA while 22 (45.83%) and 2 (4.17%) reported moderate and low intensity of PA, respectively. The mean age of the 35 participants was 26.08 ± 4.60 years. The mean duration of chest compressions was 193.25 seconds with higher times reported for those with high PA when compared to those with moderate PA ( p = 0.017). Similar findings were also observed for fatigue. Conclusion Rescuers who reported high PA had lower levels of fatigue and could perform longer duration of chest compressions.

Introduction: Immediate Bystander CPR improves the survival outcome of victims experiencing sudden cardiac arrest. Therefore, this study aimed at assessing the emergency preparedness level, training feasibility and knowledge retention of BLS skills among High School students. Materials and Methods: A total of 16 participants were included in the study by convenience sampling method. They were provided with Sudden Cardiac Arrest (SCA) scenario and were asked to perform on a CPR training manikin and assessed using a checklist. Following this session, a theoretical background and hands-on training was given to the students by an AHA certified instructor. This session was concluded by reassessing the participants. A week later, we re-assessed their skill retention. Results: The mean pre-training score was 2.6 (± 1.9). The post-training and one week recall scores was 12.44 (± 0.89) and 12 (±1.05) respectively. We observed a significant difference between the pre- and post-training scores (p<0.001). The post-training score and the one week recall scores were similar which implies that the students have good short term knowledge retention of BLS skills. Conclusion: Knowledge of basic life support skills is low among high school students. They have the ability to learn with good hands-on training and instruction. They also have good retention of the skills one week later.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
