Abstract
BACKGROUNDS: Dispatcher-guided cardiopulmonary resuscitation (CPR) via video calls represents an important shift from purely verbal instruction to real-time visual modeling for untrained bystanders during out-of-hospital cardiac arrest. This approach may improve compression depth, rhythm, overall CPR quality, and reduce interruptions. PROBLEMS: Its implementation remains challenging because voice calls may be faster, whereas video guidance requires stable connectivity, smartphone access, digital literacy, appropriate camera positioning, and trained dispatchers. Moreover, simulation findings among young university students may not reflect real emergency conditions. CONCLUSION: Video-assisted CPR should be developed as a hybrid, equitable, low-bandwidth intervention and tested pragmatically across diverse emergency systems.
