2.3 Review Standards
Arrival time was the time of transition from the emergency medical
services (EMS) stretcher to hospital gurney. Study data included all
pauses in compressions, including pauses for procedures, pulse checks,
compression device malfunction, or other causes. The case was considered
completed 5 minutes after ROSC was achieved. Time of death was the time
that death was announced. Time of ROSC was the time a palpable pulse was
announced by either the code leader or provider who palpated the pulse.
Pulse checks identifying ROSC or termination of resuscitative efforts
were not included in analysis. Primary quality metrics were pulse check
times and chest compression fractions. Secondary metrics included time
to IV access, and time to patient connection to the monitor.
