ARLINGTON, Va. -- Last month, a health researcher in the Washington, D.C., area gave CPR to a man suffering a heart attack on a local bike trail. Now he is using his experience to put a spotlight on World Restart A Heart Day on Saturday.

Bryan Buckley said he and a friend were biking when they saw a man in his late 60s drop to the ground. As a former lifeguard, he knew starting CPR quickly can double or triple a cardiac arrest victim's chance of survival.

"We were the first responders, and I looked to my buddy and said, 'You call 911,'" Buckley recounted. "And then the lifeguard in me, it all came back like it was yesterday. We ended up doing CPR, switching between three of us over about 15 to 20 minutes. And you know, in many ways, that ended up saving that man's life."

He emphasized bystander CPR is more important than ever because research shows survival of out-of-hospital cardiac arrest has dropped by 14% in 2020 compared with about 10% the year before. Go to Heart.org/HandsOnlyCPR to find out more about learning the life-saving procedure.

The Restart a Heart initiative aims to boost bystander CPR rates worldwide by encouraging folks to learn hands-only CPR. Buckley pointed out each year, more than 350,000 Americans experience cardiac arrest outside of a hospital, and about 90% of them die.

"There's also the importance of making sure that when people do call 911 that we can have the folks on the phone be able to walk people through CPR," Buckley urged. "That's one of the things I've become very passionate about."

In 2020, the Virginia General Assembly passed a law requiring all state 911 dispatchers to complete telephone CPR education by July 2024.

The Commonwealth joins six other states, including Maryland, Louisiana and West Virginia, that require telephone CPR training for dispatchers. The American Heart Association is encouraging people to join them as advocates for this type of critical legislation in other states.

People who are part of the Deferred Action for Childhood Arrivals program, known as DACA, will be dropped from their CoveredCA health plans at the end of August.

The move comes after the Trump administration changed a Biden-era definition of "lawfully present" to revoke health care eligibility for thousands of immigrants.

Christine Smith, policy and legislative advocate for the nonprofit Health Access California, said people only have a few weeks to get medical appointments in before their coverage ends.

"If you're enrolled in Covered California and you're a DACA recipient, the Trump administration just ended your coverage," Smith emphasized. "People should use as much of your health care as you can before the August 31st deadline."

The Centers for Medicare and Medicaid Services defended the move, saying it will save taxpayers money. CoveredCA estimated the change affects about 2,400 DACA recipients in the state who make too much to qualify for Medi-Cal and have jobs not providing health insurance. They can still buy private insurance but it is much more expensive. People who prepaid for their coverage can seek a refund.

Smith predicted it will be a blow not just to those who lose coverage but to the state's health care system as a whole.

"The lines in the ERs are going to be longer because people are not going to be able to get affordable preventive care," Smith projected. "They're just going to get sicker and then end up in the ERs. People will overall incur more medical debt. Hospitals will have more uncompensated care."

The change is nationwide. As of mid-July, about 538,000 people in the DACA program across the U.S. are ineligible to enroll in any state-based insurance marketplace and are unable to access premium subsidies or cost-sharing assistance.

Artificial intelligence is appearing more prominently in many aspects of life and research suggests older populations are curious, yet remain wary of using the technology in their everyday lives.

According to Stats Indiana, there are more than 1.5 million Hoosiers aged 65 and older, or 18% of the state's population. Experts said it is likely the demographic will use AI in some form in the next few years, either by choice or necessity.

Dr. Shaun Grannis, vice president of data and analytics for the Regenstrief Institute on Aging, said AI offers real benefits.

"It can reduce loneliness through conversation, provide reminders for medications and appointments," Grannis outlined. "It can support cognitive stimulation via games, storytelling, news updates."

The technology can also offer a low-pressure way to access information on public services, he added, which is valuable for those with mobility issues or those who feel intimidated by technology.

Grannis cautioned any tool which can be used for good can also lead to problems. He noted AI can create a false sense of companionship and mask social isolation. Overdependence is a legitimate concern, he argued, if the technology becomes a "crutch" for all forms of interaction.

"All cognitive activities or decision-making, it can actually lead to and create a negative feedback loop, lead to a decline in engagement and even basic self-management skills," Grannis explained. "This is risky."

Grannis believes one solution is designing AI systems to complement, not replace, human interaction. He stressed it can be done though building broader support ecosystems including family, friends, caregivers and community services. Grannis emphasized it would encourage real-world activity, prompting the user to go for a walk, call a grandchild or attend a local senior event.

If you have an extra five minutes, you can save a life because you can learn cardiopulmonary resuscitation at no cost from a new mobile, hands-only CPR kiosk.

The new kiosk is in the lobby of Saint John's Health Center in Santa Monica. The machine's touch screen gives a brief overview of hands-only CPR and you can practice right there, on a mannequin.

Dr. Rigved Tadwalkar, cardiologist at St. John's, said it is an easy way for people to get more comfortable giving chest compressions in an emergency.

"It's a lot like a video game but of course, a lot more important than a video game," Tadwalkar pointed out. "It gives real-time feedback about the depth and rate of compressions, proper hand placement, which are all factors that influence the effectiveness of CPR."

The American Heart Association operates the St. John's mobile kiosk and a stationary model at L-A-X with support from the hospital. Santiago Canyon College in Orange County also has a mobile hands-only C-P-R kiosk now through September, sponsored by Edwards Lifesciences.

Steven Munatones, an Orange County business owner, said he survived what's known as a "widowmaker" heart attack which led to cardiac arrest nine years ago, thanks to his 17-year-old son, who gave him immediate CPR with instructions from a 911 operator.

"You don't have to put your mouth to anybody's mouth," Munatones explained. "You just put your hand on their chest and pump. He saved me, and others can do the same, anywhere. So, it's absolutely a lifesaving, heroic act that anybody can do."

Statistics show 350,000 Americans suffer from cardiac arrest outside a hospital each year and about 90% die, in part because they do not receive CPR. About 70% of those cardiac arrests happen at home, so people often depend on family or friends to give CPR before an ambulance arrives.
