The time from arrival on-scene to the patient’s side is important, particularly in multistory buildings
Significant delays present when accessing patients in high-rise buildings and evacuating them to the hospital.
US National NEMSIS cardiac arrest elapsed patient care times as an average (table) and as a 90th Fractile (graph).
Pivotal 2005 study establishes no survival benefit from EMS arrival within 8 min – only if within 4 min.
In large cities traffic and access to building complexes are serious obstacles to SCA rescue vehicles. On-site AEDs and elevators are a lasting and obvious solution.
Police dispatchers handle more AED calls than any other agency, and pinpointing which ones are true SCA’s is difficult.
