Bystander Fatigue and CPR Quality Using Continuous Compressions Versus 30:2 Compressions to Ventilation

STUDY OBJECTIVES The overall goal of this study is to compare bystander fatigue and CPR quality after 5 minutes of continuous chest compressions versus the 2005 30:2 chest compression to ventilation Resuscitation Guidelines, in a population aged 55 or greater. More specifically, the investigators will compare each CPR ratio with regard to: 1. The achieved frequency and depth of chest compressions, and 2. Participant rating of their perceived level of exertion. STUDY HYPOTHESIS In a population aged 55 or greater, the new CPR recommendations will lead to: 1. less frequent and shallower chest compressions over the 5-minute study period; and 2. higher rating of perceived level of exertion when compared to the 2005 30:2 CPR ratio.
