Overview

Observational study assesses AED deployment in Xuzhou, revealing 53% of OHCAs within walking distance, indicating improved strategies are needed.

Key Points

  • The optimal AED deployment distance calculated to be 270–280 m, aiming for better coverage in communities.
  • Average of 53.04% of OHCAs had AED access within the golden window walking distance of 4–6 minutes.
  • Using Geographic Information System, the study simulated improved AED placement efficiency based on walking-route distances.
  • Model highlights the gap in current AED deployment and suggests smart allocation for future drone delivery systems.
