Improving Accuracy in Cardiopulmonary Resuscitation Training: Results on Undergraduate Nursing School Students’ with OMNI2 Simulator

Cardiopulmonary resuscitation (CPR) is a vital skill for healthcare professionals, crucial in life-saving situations. More than 80% of cardiac arrest cases occur out of hospital. As the demand for competent CPR practitioners grows, the effectiveness of training methods becomes increasingly important, especially for undergraduate students preparing to enter the healthcare field. The primary objective of our study is to investigate the effectiveness of simulation-based teaching methods and by integrating innovative technologies, such as the OMNI2 stimulator, to improve the precision and objectivity of CPR instruction. A cohort of 144 undergraduate students from the Nursing School Department of the National Kapodistrian University of Athens participated in an 8-hour Basic Life Support Seminar. It consisted of 5 hours theoretical instruction followed by 3 hours of practical training using the OMNI2 simulator. Each student was tasked with identifying cardiac arrest and performing two cycles of CPR according to the 2021 guidelines. Metrics, including total session time, cycles performed, compression-to-ventilation ratio, compression depth, compressions and ventilations per minute, full recoil, peak inspiratory pressure, and ventilation duration, were measured and compared against the stimulator's specified targets. Statistically significant differences (p < 0.05) were observed across all parameters, except for peak inspiratory pressure. Concluding, while simulation-based teaching has conventionally been proven effective for CPR proficiency, real-time data collected in this study reveal a disparity between anticipated and actual performance. Our research underscores the necessity of refining instructional methods to enhance accuracy, potentially leading to improved patient outcomes in the future.
