Problem: degraded foam could form potentially carcinogenic volatile organic compounds (VOCs).

On July 8, 2021, the Medicines Agency has brought together a committee of experts made up of representatives of associations of users of the health system as well as personalities qualified by virtue of their skills in general medicine, pneumology, toxicology, medical devices and epidemiology, in order to better understand the potential risks associated with the use of these defective devices. To date, the ANSM received nearly 300,000 reports of adverse effects.

As of December 2021, these tests revealed reassuring results on VOC emissions 1st generation DreamStation devices. Similarly, over an identical period, a completely independent Canadian study, published in the American Journal of Respiratory and Critical Care Medicine and carried out on approximately 6,900 patients with OSAS who used a PAP device between 2012 and 2020, of which approximately 1,200 users of Philips CPAP devices, did not show a higher risk of cancer in the latter, compared to patients using a CPAP device from another manufacturer or to patients with OSAS without a device.
