More bystanders performing CPR on individuals experiencing cardiac arrest

Reuters reports that two studies published in JAMA indicate that more bystanders are performing cardiopulmonary resuscitation (CPR) on individuals experiencing cardiac arrest, and their efforts may be leading to better outcomes.

On its website, NBC News reports that in the first study, researchers found that “in North Carolina in 2010, just 14 percent of people who collapsed with cardiac arrest got CPR until a professional could arrive and use a defibrillator,” but “this rose to 23 percent by 2013, after a statewide campaign to encourage the use of CPR.”

The researchers found that “in 2010, just 7 percent of people lived without brain damage but by 2013 nearly 10 percent did.”

TIME reports that the “second study … looked at 167,912 patients with bystander-witnessed out-of-hospital cardiac arrest between 2005 and 2010.”

The researchers found, “during the time period…that the number of events increased, as did the rate of bystander chest compression and bystander defibrillation.”

The investigators saw “an association between these higher rates and a small increase in the likelihood that people survived without neurological damage.”
