Quality of Cardiopulmonary Resuscitation Guided by AED vs Telephone-assistance

Study Overview
=================
Brief Summary
-----------------
The aim of this research is to evaluate and to compare the quality of cardiopulmonary resuscitation (CPR) among untrained laypeople under two different scenarios: automated external defibrillator (AED) guided CPR or dispatcher-assisted CPR. Secondarily, to evaluate the quality of the dispatcher-assisted instructions provided from the emergency call center.

Detailed Description
-----------------
A simulation study will beperformed. 42 volunteers selected by non-probabilistic sampling will be randomized in two scenarios of cardiac arrest on mannequin: (A) AED-guided CPR and (T) dispatcher-assisted CPR. Simulations last 9 minutes. The quality of CPR will be evaluated by metric monitoring of the chest compressions and timing of actions. A peer's content analysis of the telephone instructions will be performed using a checklist.
