(Press-News.org) Philadelphia, July 30, 2025 – Despite widespread public health efforts, the dangerous myth of "prevention of tongue swallowing" continues to persist during cardiopulmonary resuscitation (CPR). New research in the Canadian Journal of Cardiology, published by Elsevier, exposes the mainstream and social media’s detrimental role in perpetuating this misconception, which often leads to critical delays in proper CPR for collapsed athletes.
Concern about “tongue swallowing” leads resuscitators to waste valuable time trying to remove the tongue from the airway path, rather than immediately initiating essential CPR procedures. The findings from this analysis underscore an urgent need for global public health campaigns to correct CPR myths and emphasize the importance of immediate chest compressions. The study systematically analyzed 45 cases of athletes collapsing during sports events (1990–2024) that were caught on video or documented online, focusing on initial resuscitation actions and corresponding media coverage.
Commenting on the main findings of the analysis, lead investigator of the article "The Myth of “Tongue Swallowing” Delays Cardiopulmonary Resuscitation of Athletes With Cardiac Arrest, Yet It Is Often Perpetuated by the Media" Dana Viskin, MD, Department of Cardiology, Tel Aviv Sourasky Medical Center and School of Medicine, Tel Aviv University, says, “Our analysis showed that in 84% of cases where the initial response was visible, inappropriate maneuvers to ‘prevent tongue swallowing’ were performed before proper CPR. These incorrect actions were significantly associated with poor outcomes: 67% of those receiving such maneuvers died or had severe brain injury, compared to 0% when CPR was the first response.”
Media analysis revealed that nearly half (48%) of high-exposure news articles explicitly used the term “tongue swallowing,” with most praising the lay responder for their actions. In articles describing sudden cardiac arrest (SCA) cases, 77% referenced “tongue swallowing” without acknowledging its inappropriateness as a response to SCA, yet only 23% explicitly criticized the intervention.
“Given that some SCA patients, particularly young males with shockable arrest rhythms, may exhibit seizure-like activity at onset – a pattern frequently observed in sports-related SCA – it is understandable how this myth may have carried into the public response to athletic SCA, despite the absence of clinical guideline support for such an intervention,” points out the author of the accompanying editorial "Countering Misinformation in the Response to Sudden Cardiac Arrest in Athletes" Nicholas Grubic, MSc, Division of Epidemiology, Dalla Lana School of Public Health, University of Toronto. “Furthermore, signs such as cyanosis and agonal respirations can be mistaken for choking, often prompting bystanders to prioritize airway inspection over initiating CPR. Recent qualitative research has confirmed that such misinterpretations can delay or even interrupt life-saving interventions. Although promoting CPR and automated external defibrillator (AED) knowledge remains a cornerstone of SCA education, teaching the public to recognize the early signs of an arrest is equally critical, as every second without action drastically reduces the chance of survival.”
This research is especially important now, as public CPR education becomes increasingly vital with widespread media exposure to cardiac arrests in sports.
"Our study highlights the dangerous and persistent misconception of ‘tongue swallowing prevention,’ which can delay the initiation of life-saving chest compressions. These delays may cost lives, and yet the media often praise such misguided actions as heroic. We urgently need to re-educate the public and the media and reframe the narrative around CPR, especially in sports," emphasizes Dr. Viskin.
Mr. Grubic adds in conclusion, “Coordinated, evidence-informed communication strategies are essential to counter misinformation and support public understanding, particularly in high-stakes situations such as the response to SCA in athletes. Our public capacity to save lives should not be impeded by misinformed voices – now is the time for the academic, healthcare, and media sectors to join forces and build a healthier information environment for all. Responding to SCA is a team sport that starts with proper education to ensure that everyone is ready to step in, stay focused, and act. Although the prize is not a trophy, it is something much more valuable.”

Hydroquinone-buffered covalent organic frameworks for long-term photocatalytic hydrogen peroxide production
2025-07-30
Hydrogen peroxide (H₂O₂) is an essential eco-friendly oxidant, but its conventional anthraquinone-based production is energy-intensive and generates hazardous waste. Photocatalysis offers a sustainable, solar-driven alternative. Organic polymer photocatalysts, notably covalent organic frameworks (COFs), have gained attention due to their tunable structures, earth-abundant elements, and visible-light responsiveness. Although recent advances (e.g., polarity-optimized, fluorinated, or sulfone-containing COFs) have improved H₂O₂ yields and extended stability to 336 hours, long-term durability remains limited. Most systems exhibit reaction times of less than 200 hours ...
From coal to chemicals: Breakthrough syngas catalysis powers green industrial future
2025-07-30
Two decades-long catalytic journey has borne industrial fruit—greener, cleaner, and smarter. Fischer–Tropsch synthesis (FTS) and heterogeneous hydroformylation are two cornerstone processes in modern chemical manufacturing. They convert syngas (a mixture of CO and H₂, typically derived from coal or biomass) into hydrocarbons and oxygenates that underpin fuel, plastics, and pharmaceutical industries. Yet for over a century, challenges in selectivity, catalyst longevity, and process integration have limited their broader industrial deployment—until now.

From the lab to the hand: nanodevice brings personalized genomics closer to reality
2025-07-30
Osaka, Japan – DNA holds the instructions that make us who we are. If we want to read those instructions, say to understand our predisposition to genetic disorders, we need to carefully ‘unzip’ DNA’s iconic double-helix structure. This is neither easy nor fast, and the process involves intense heating and chemicals that can damage the DNA.
Now, in a new study published in ACS Nano, a research team led by The University of Osaka has developed a novel technology for making the unzipping process much easier. Their invention uses a miniature heater to precisely and gently unzip the DNA double helix.
The device uses a nano-sized platinum coil. As the DNA strand reaches ...
