Work of CPR Study

STUDY BASICS

Are you CPR-certified by the American Heart Association or Red Cross? You may be able to participate in a research study to help learn more about the relationship between fitness levels and CPR quality over time. This study involves up to 4 visits over 3 months. Compensation is provided.

STUDY PURPOSE

For CPR (cardiopulmonary resuscitation) to be effective, the rescuer must be able to perform high-quality chest compressions. Previous research suggests that lower fitness levels may hinder a rescuer’s ability to deliver adequate compressions by causing them to fatigue more quickly, but this relationship is not fully understood. The purpose of this study is to help better understand the relationship between a person’s fitness levels and CPR quality over time.

COULD THIS STUDY BE RIGHT FOR YOU?

• Men ages 18 and up
• CPR-certified (Red Cross or American Heart Association CPR Certification Card)
• No history of heart or liver disease
• No musculoskeletal problems that may prevent you from performing CPR
• Not taking a beta blocker or any other medication that may lessen your body’s response to exercise or stress
• No tobacco use, including smoking, chewing, vaping, etc.
• BMI (body mass index) is 30 or under (https://www.nhlbi.nih.gov/health/educational/lose_wt/BMI/bmi-m.htm)

WHAT PARTICIPANTS CAN EXPECT

This study involves up to four visits over three months. During the initial 30-minute screening visit, participants will provide a medical history and have a physical exam. If eligible, participants will have three additional visits. Study procedures will include tests of exercise capacity, muscle strength, and CPR performance.
