Summary
Audiovisual guidance using animated GIFs significantly improved cardiopulmonary resuscitation (CPR) performance and posture compared to auditory-only instructions. This enhances dispatcher-assisted CPR effectiveness for bystanders.
Area of Science:
- Emergency Medicine
- Cardiopulmonary Resuscitation
- Medical Simulation
Background:
- Bystander cardiopulmonary resuscitation (CPR) is critical but often performed with suboptimal technique.
- Few studies have evaluated methods to improve bystander CPR performance during dispatcher-assisted scenarios.
Purpose of the Study:
- To compare the effectiveness of dispatcher-assisted CPR using audiovisual guidance (animated GIFs) versus auditory-only guidance on bystander CPR performance and quality.
- To analyze differences in CPR technique and adherence to instructions.
Main Methods:
- 80 untrained adults were randomized into auditory-only or audiovisual (smartphone GIFs) groups for dispatcher-assisted CPR simulation.
- Participants performed 2-minute adult and infant CPR, recorded via video.
- CPR performance and quality were assessed by emergency physicians and manikin feedback devices.
Main Results:
- The audiovisual group demonstrated significantly higher performance scores in posture and instruction adherence for both adult and infant CPR (p < 0.001).
- Audiovisual guidance also improved adequate compression rate ratio in infant CPR (p = 0.047).
- No significant difference in overall CPR quality was observed between groups for adult CPR.
Conclusions:
- Animated GIF-based audiovisual guidance enhances bystander CPR Standard Posture Completeness and Instruction Performance more effectively than auditory guidance alone.
- This technology offers a promising approach to improve dispatcher-assisted CPR outcomes.
