Continuous positive airway pressure (CPAP) devices made by Philips Respironics Inc. are still presumed by the U.S. FDA and other regulators to present a health hazard to patients, but the company’s latest data seem to suggest otherwise. In a Dec. 21 statement, the Royal Philips subsidiary said that testing suggests no appreciable harm to health related to particulate matter emissions from the polyester-based polyurethane (PE-PUR) foam in these devices, and that there is no evidence of long-term harm associated with volatile organic compounds (VOCs), both of which are conclusions with which the FDA may not agree.
