(Reuters Health) - Even though high schools in most U.S. states are required to offer training in cardiopulmonary resuscitation (CPR) to students, many do not, a new study suggests.
Nationwide, more than 350,000 people have a cardiac arrest outside of hospitals each year, researchers note in a report scheduled for publication in the Journal of the American College of Cardiology. Patients’ survival odds improve when a bystander at the scene performs CPR, but only about 2.4 percent of Americans are trained in CPR each year.
To get more people trained, 39 states had passed legislation requiring CPR training in high schools as of September 2017. But when researchers surveyed administrators at schools in 32 states with mandatory CPR, only 77 percent of respondents said they provided this training.
“One major barrier for schools is the cost of CPR training,” said lead study author Dr. Lorrel Brown of the University of Louisville School of Medicine in Kentucky.
“High-quality mannequins are expensive and certified instructors are not always readily available,” Brown said by email. “The majority of states do not provide funding for CPR training, and therefore individual districts and schools are left to implement the requirement in their local context.”
Cardiac arrest involves the abrupt loss of heart function, breathing and consciousness. Unlike a heart attack, which happens when blood flow to a portion of the heart is blocked, cardiac arrest occurs when the heart’s electrical system malfunctions, disrupting the heart’s rhythm or halting it altogether. Cardiac arrest may occur with no warning and is often fatal.
Chest compressions or CPR can help restore circulation, increasing the odds of survival. Bystander CPR generally won’t restore a normal heart rhythm, but it can buy time by maintaining blood flow to vital organs.
For the study, researchers identified 32 states with CPR laws using the American Heart Association’s “CPR in Schools” website in June 2016. Maine was unintentionally omitted due to misidentification on the website.
Researchers worked with education officials in each state to email surveys on CPR programs to superintendents and school principals. A total of 424 of 25,694 eligible high schools participated.
Most schools that offered training had a CPR-certified teacher or coach do the lessons, but 11 percent had instructors who were not certified in CPR, the study found.
Nearly all percent of schools with CPR training included hands-on lessons in CPR, the study found.
But only 63 percent of schools trained their students to use automated external defibrillators (AEDs), which are commonly available in public places like restaurants and airports.
The study wasn’t a controlled experiment designed to prove whether or how state CPR training laws influence the proportion of people in the community who know CPR or actually use it in an emergency.
“Schools are low-hanging fruit from a public training standpoint,” Dr. Christopher Fordyce of the University of British Columbia, who wasn’t involved in the study, said in an email. “They not only provide an opportunity for large-scale, mass training, but they theoretically straddle socioeconomic barriers and reach a wide demographic.”
When schools don’t teach kids CPR, parents should step up, said Dr. Graham Nichol, director of the University of Washington-Harborview Center for Prehospital Emergency Care in Seattle.
“The take-home message for parents is to make sure that their kids and they themselves have been trained in how to recognize cardiac arrest, perform CPR and apply an AED before the arrival of EMS providers on the scene,” Nichol, who wasn’t involved in the study, said by email.
Even without formal CPR training, people can learn the basics, Brown said.
“Press hard and fast in the center of the chest to the beat of the song `Stayin’ Alive’ or the Darth Vader theme song, `Imperial Death March,’” Brown advised. Instruction videos are on Brown’s website: www.alivein5.org/
“We as a CPR community are still searching for and investigating the best method of CPR training that is effective and efficient,” Brown said. “But any training is better than no training.”
