Summary

STUDY OBJECTIVES The overall goal of this study is to compare bystander fatigue and CPR quality after 5 minutes of the new 30:2 versus the old 15:2 chest compression to ventilation International Resuscitation Guidelines, in a population aged 55 or greater.

More specifically, we will compare each CPR ratio with regard to:

1. The achieved frequency and depth of chest compressions,
2. Participant rating of their perceived level of exertion, and
3. Resulting serum lactate levels in a subset of the participants.

STUDY HYPOTHESIS

In a population aged 55 or greater, the new 30:2 CPR ratio will lead to:

1. less frequent and shallower chest compressions over the 5-minute study period;
2. higher rating of perceived level of exertion; and
3. higher serum lactate levels in a subset of participants when compared to the old 15:2 CPR ratio.
