Last year in June, when a woman collapsed on an escalator at Buffalo's airport, and Phil Clough, who is an experienced emergency medical responder knew exactly what to do. He and a bystander, as the Washington Post reported, quickly laid the woman flat on her back. They checked her pulse and breath. Her pulse was faint and her breathing was shallow and erratic. A few moments later, she stopped breathing altogether. Realizing she might be experiencing a cardiac arrest, Clough immediately began performing chest compressions. He pressed hard and fast on the center of her chest while other bystanders called 911 and fetched an automated external defibrillator (AED). Within seconds of receiving a shock from the AED, the woman opened her eyes. By the time the airport rescue team arrived, just minutes later, she was conscious and able to speak.Clough’s quick actions saved the woman’s life, but he credits his preparedness to a life-changing incident several years earlier. After witnessing a woman collapse at his gym and feeling helpless, he took a college course to become certified as an emergency medical responder. This training allowed him to respond with confidence when faced with a life-or-death situation.The Challenge of Cardiac ArrestThe woman in Buffalo was fortunate that bystanders knew how to respond. Unfortunately, most people who experience cardiac arrest do not receive immediate help. According to the American Heart Association, more than 350,000 cardiac arrests occur outside of hospitals in the U.S. annually. Tragically, 90% of these individuals do not survive, often because help arrives too late. For each minute that passes without intervention, a person’s chances of survival decrease by 10%. However, with prompt cardiopulmonary resuscitation (CPR) and an AED shock if necessary, survival rates can double or even triple.Despite the importance of swift intervention, fewer than half of people who suffer cardiac arrest outside of a hospital setting receive immediate assistance. This lack of action is often due to a lack of training and preparedness. Cardiac arrest can happen anywhere, but with public access to AEDs and trained bystanders, survival rates could improve dramatically.The Role of AEDs in Saving LivesA crucial part of treating cardiac arrest is the use of an AED, a portable device that delivers an electric shock to the heart. The AED analyzes the heart’s rhythm and guides the user through the steps to apply a shock if needed. Although many states require AEDs to be available in public places such as airports and malls, they are not always easy to find. A study spanning 2019 to 2022 revealed that in public settings, AEDs were used only 7% of the time, and CPR was performed 42% of the time after a cardiac arrest incident.To address this issue, PulsePoint, a nonprofit organization, has registered 185,000 AEDs in 5,400 U.S. communities, reports the Washington Post. The group’s goal is to help communities build their AED registries and integrate them with local 911 services. In addition, PulsePoint’s mobile app alerts trained CPR responders about nearby cardiac arrests and identifies the closest AEDs, enhancing the chances of saving a life.Overcoming Barriers to Bystander InterventionWhile CPR and AED knowledge can save lives, many people hesitate to intervene during an emergency due to fear of making a mistake, lacking confidence, or worrying about legal liability. However, all 50 states and Washington, D.C. have “Good Samaritan” laws that protect individuals from legal consequences when they provide help in a medical emergency.Lack of CPR training is another significant barrier. A study found that only 18% of people had received CPR training within the last two years, which is crucial for skill retention. Although many people have received CPR training at some point in their lives, the skills may be outdated or forgotten.To address this, some states have made CPR training mandatory for high school graduation, and countries like Denmark and Norway have implemented similar requirements. In the U.S., CPR courses are widely available online and in-person, and many take just a few hours to complete. These courses teach individuals the basics of CPR, which involves performing chest compressions at a rate of 100 to 120 per minute and a depth of at least two inches.
