Mathematical determination of external defibrillators needed at mass gatherings[1]

Crocco TJ, Sayre MR, Liu T, Davis SM, Cannon C, Potluri J · 2004 · Prehosp Emerg Care

Summary

Empirical time-distance study using 20 volunteers responding to mock arrests in a stadium across seven scenarios (three stairway slopes ascending/descending plus level ground, each in empty and full-stadium congestion), yielding a formula: total AEDs = sum over slope classes of area divided by (stair distance x achievable horizontal distance) for a target response time. Lets a medical director compute AED count from venue geometry and their chosen time-to-shock goal.

So what

The only published method that converts the venue AED question from opinion to arithmetic: pick a time-to-defibrillation target (Wassertheil/Valenzuela argue <=3-5 min), measure the stairs, and the count falls out. Congestion-adjusted by design. The natural companion to the resuscitation-outcome shelf and a candidate calculator feature for MGMI.

Key findings

  • Empirical stair-slope/congestion time-distance curves from stadium trials
  • Formula: AED count from venue areas, slopes, and target response time
  • Anchors AED provisioning to the 3-5 minute survival window
  • Candidate MGMI calculator module
