This study refined a method to calculate the number of automated external defibrillators (AEDs) needed for rapid emergency response at large public events. The validated approach ensures adequate AED placement for critical 3-minute response times.

Area of Science:

  • Emergency Medicine
  • Public Health Preparedness
  • Sports Medicine

Background:

  • Determining optimal automated external defibrillator (AED) placement is crucial for emergency response at mass gatherings.
  • Previous methods for calculating AED requirements exist, but require modification and validation for diverse venues.

Purpose of the Study:

  • To modify, replicate, and validate a method for calculating the number of AEDs required for a 3-minute emergency response time at mass gatherings.
  • To assess the applicability of the method in different large-scale venues like stadiums and arenas.

Main Methods:

  • Emergency medical technicians (EMTs) traversed timed courses in a football stadium and basketball arena to determine walking velocities.
  • Velocities were measured across horizontal distances and ascending/descending different seating decks.

  • Predicted response times were calculated using pessimistic velocity estimates (second standard deviation), and AED numbers were based on the longest venue distances.

    • Main Results:

    • Average walking velocities varied by venue and terrain (e.g., football: horizontal 1.7 m/s, upper deck 1.0-1.1 m/s; basketball: horizontal 1.7 m/s, upper deck 0.9 m/s).
    • All EMTs completed validation courses within predicted intervals.
    • Predicted longest-distance response times were 363 seconds (football stadium) and 187 seconds (basketball arena).

    Conclusions:

    • The modified method for calculating AED requirements is easily replicable and practical for mass gathering venues.
    • The number of AEDs can be determined for any specified response interval, such as the critical 3-minute target, based on venue-specific longest-distance predicted response times.
