Child Deaths from Helium Inhalation

Karlton Noah Donaghey, a five-year-old boy, tragically died on June 23, 2022, after inhaling helium from a balloon. His elder sister, Caitlin, is now campaigning to raise awareness about the fatal consequences of helium inhalation, highlighting that even a single breath can displace oxygen and lead to brain death. The family was unaware of the dangers, and despite efforts to make the balloon safer, Karlton Noah Donaghey managed to access it. Caitlin's campaign is fueled by her personal loss and the knowledge of other similar incidents, such as the deaths of Brodie Lee in 2021 and Joshua Dunbar in 2024, both due to helium balloons. Coroners have emphasized that while helium is not poisonous, it prevents oxygen from reaching the body. Caitlin is also concerned about the trend of inhaling nitrous oxide and its use as a suicide method. She advocates for stronger regulations, warning labels on helium products, and urges parents to avoid buying helium balloons altogether, suggesting air-filled alternatives. The United Kingdom — Office for Product Safety and Standards, Israel — Standards Institution of Israel, British Toy and Hobby Association, and British Retail Consortium have been contacted for comment on these safety concerns.
