Video CPR guidance beats Phone-Only in noisy, dark settings

This study tested whether video calls (V-CPR) help bystanders perform better CPR than phone-only instructions (T-CPR) in both ideal and challenging conditions like noise or poor lighting. 157 healthy volunteers performed CPR on a manikin while being guided by a dispatcher. The goal was to see if seeing the scene improves compression depth, rate, and hand placement. Results will show whether video assistance is more effective in real-world distractions.
