Philips Respironics, a subsidiary of Royal Philips, is under scrutiny for its handling of complaints about its breathing machines, which were found to have a potentially harmful foam component. The company received complaints about the foam as early as 2010 but did not alert the FDA or the public until a recall in June 2021. The foam, used to reduce noise in the machines, was found to degrade and release potentially toxic and carcinogenic particles. Despite internal warnings, Philips continued to sell the machines, which were used by children, the elderly, and at least 700,000 veterans. The company is now facing numerous lawsuits.
