Abstract 231: Single Bystander CPR Performance During Drone AED Delivery for Simulated Out of Hospital Cardiac Arrest

Background: Drones have great potential to speed the delivery of AEDs in the critical first few minutes of OHCA. However, it is unclear whether bystanders can balance high-quality cardiopulmonary resuscitation (CPR) with AED deployment. The 2015 AHA CPR guidelines recommend a chest compression (cc) rate of 100-120/minute, cc depth of 50-60mm, and cc fraction of >60%. Method: We performed mock cardiac arrest simulations using bystander volunteers, including simulated 911 call, telephone-assisted dispatcher CPR instructions, bystander CPR, drone-delivered AED, and AED application. CPR performance was recorded by a Laerdal Resusci Anne Quality Feedback System and compared between two groups of participants: recent CPR training (<2 years) versus remote (>2 years) or no CPR training. Prior data had shown CPR skill degradation after 2 years. Chi-squared tests compared demographics; T-tests compared age and CPR performance data. Results: Between 9/2019-3/2020, 5 simulations were conducted with 51 participants. The mean age was 39.7 years, 56.9% were female, and 78.4% had a college or graduate degree. Racial/ethnic makeup consisted of 64.7% White, 15.7% African-American, 15.7% Asian, and 11.8% Hispanic. 41.2% had recent CPR training (n=21); 58.8% had remote CPR training (n=19) or no CPR training (n=11). There were no differences in demographics by CPR training groups. Participants with recent CPR training had shorter time from CPR initiation to AED shock delivery (3:45 vs. 4:14 [min:sec], p=0.01) and a trend toward higher percent of time with cc depth (77.4% vs 50.4%, p=0.11) and higher cc fraction (46.8% vs 42.9 %, p=0.12). There were no differences for percent of time with cc rate or CPR recoil. Conclusion: Overall, CPR quality was low regardless of prior CPR training status. Those recently trained had shorter resuscitation time and appeared to have better CPR performance. Realization of a drone AED networks may require novel CPR programs focused on high-quality CPR.
