Abstract P68: Real Time Cardiopulmonary Resuscitation Instructions via Cellular Phone
Objectives: Bystander CPR can improve survival from cardiac arrest, but it is often underutilized because of bystander’s perceived inability of how to perform CPR correctly. We sought to evaluate the efficacy of using a cellular phone to provide audio pre-recorded CPR instructions.
Methods: We recruited CPR trained and untrained veterans at a VA medical center and randomly assigned them to simulate resuscitating a mannequin for 3 minutes with or without assistance from a cellular phone programmed for “chest compression only” CPR instructions. We compared CPR quality metrics: compression rate (compressions/min), compression depth (mean), and hand placement (percent correct) across groups (previous CPR training- phone vs. no phone and no previous CPR training- phone vs. no phone.
Results: Of 161 subjects, 94% were male, mean age 52+/−7years. Pre-simulation, 31% (26/83) of CPR trained veterans felt “excellent/very good” about their ability to perform CPR vs. 37% (29/78) of those untrained. CPR trained individuals using the phone demonstrated better compression rate (62/min vs. 32/min; p<.05) and depth (43mm vs. 33mm; p<.05) compared with trained individuals without the phone. Hand placement was not significantly different for trained individuals with and without the cell phone (45% vs. 50% correct; p=.66). Untrained individuals using the cell phone had better compression rate (58/min vs. 36/min; p<.05), depth (39mm vs. 29mm; p<.05), and similar hand placement (54% correct vs. 54% correct; p=.99) compared with untrained individuals without the phone. Post-simulation, CPR ability was rated as “excellent/very good” by 77% (33/43) of CPR trained individuals+ phone compared with 45% (18/40) of trained individuals without the phone and 68% (28/41) of untrained individuals3 phone compared with 24% (9/37) of untrained individuals without the phone.
Conclusion: CPR quality parameters (compression rate/depth) and perception of performance was better for trained and untrained individuals when assisted by a cellular phone. If our simulated results are generalizable, a simple audio program can be made available for all cellular phones (regardless of phone sophistication) to potentially improve out-of-hospital resuscitation.
