Study participants who viewed a brief hands-only cardiopulmonary resuscitation (CPR) video were more likely to attempt CPR, and perform better quality CPR in an emergency than participants who did not view the short videos, according to research reported in Circulation: Cardiovascular Quality and Outcomes.
Each year, almost 300,000 people suffer out-of-hospital cardiac arrests in the United States. Survival rates from these events tend to be extremely low. However, research has shown that bystander CPR can double — even triple — survival from out-of-hospital cardiac arrest.
In the United States, bystanders attempt CPR only about 26 percent of the time, according to Bentley J. Bobrow, M.D., lead author of the study and clinical associate professor in the Department of Emergency Medicine in the Maricopa Medical Center in Phoenix, Arizona and the University of Arizona Emergency Medicine Research Center.
“Chest compression-only CPR, also known as hands-only CPR, has been shown in studies to be at least as effective as standard CPR with mouth-to-mouth ventilation for adult primary cardiac arrest victims,” Bobrow said. “And because of its simplicity, hands-only CPR may be quicker and easier for lay rescuers to learn, remember and perform than conventional CPR.”
Bobrow and colleagues conducted a study of 336 adults without recent CPR training and randomized the participants into four groups:
- No training (control group of 51 participants)
- Ultra brief video (UBV): watched a 60-second video (95 participants)
- Brief video (BV): watched a five-minute video (99 participants)
- Brief video with practice (BVP): watched an eight-minute video with a practice training session using a manikin (91 participants)
