Abstract 466: Consideration of an Optimal Educational Strategy for High-Quality Cardiopulmonary Resuscitation and Chest Compression Fraction in Basic Life Support Simulation Training

Abstract

Introduction: The American Heart Association (AHA) is pursuing higher-quality simulation training with the goal of “Optimizing educational strategies for healthcare providers” as one of the Science Gaps in the 2015 Cardiac Arrest Guidelines. The latest guidelines suggest that increasing CCF as much as possible during CPR increases the chance of ROSC. However, in simulation training, it is important to evaluate the percentage of CCF and maintain high-quality CPR. We evaluated CPR for 10 minutes in a “High-Performance Teams Activity” of an AHA-BLS course using the HQCPR quotient and CCF indexes. Methods: We measured the rhythm chest compressions (CCs), duration of two breaths, and chest rise two times using a bag valve mask, interruption and alternation time of CC, CC resumption time after AED (shock or no shock), and CCF, which was calculated from CPR recorded for 10 minutes using the video camera. This data was evaluated using the criteria of high-quality CPR based on AHA-BLS guidelines comprising 7 items, such as “100-120 frequency per min for CC,” and the HQCPR quotient was determined. The HQCPR quotient and CCF of each team were analyzed using logistic analysis. Moreover, the BLS techniques of each teams, such as the rhythm CCs were compared with the CCF of each teams, respectively. This study was approved by the Ethics Committee of Ryukyu University and the Japan ACLS Association. Results and Conclusions: Overall, 48 teams comprising 215 subjects participated in the study. The HQCPR achievement rate for the 48 teams was 65.9%. There was no correlation between the HQCPR quotient and CCF (R2 = 0.0003). In simulation training, the CCF height did not necessarily guarantee high-quality CPR (Figure 1). In particular, as CCF increased, the duration of two breaths decreased (R2 = 0.46). An adverse effect of breaths for a very short time was noted. We propose that it is essential to evaluate CCF with HQCPR quotient to achieve “Optimizing educational strategies for healthcare providers.”
