NCT00539539

Brief Summary

The purpose of this study is to evaluate whether or not real-time feedback on CPR process variables will increase rates of restoration of spontaneous circulation during prehospital resuscitation and upon arrival at the receiving emergency room as well as increase rates of survival to hospital discharge.

Study Arms (2)

Feedback On

ACTIVE COMPARATOR

Automated real-time feedback on CPR Process activated

Other: Laerdal Q-CPR /technology

Feedback Off

NO INTERVENTION

For the first three to six months, participating EMS agencies will have defibrillators with automated, real-time feedback inactivated. During this period, the baseline rate of ROSC (and secondary outcomes) will be collected. At the end of this baseline period, EMS agencies will be randomized to one of two interventions, with randomization stratified within site by agency, station, or device. All clusters will cross-over to the opposite feedback strategy at least once during the intervention phase.
