From the American Academy of Sleep Medicine:
This notice contains an important health and safety update. Please read this notice in its entirety.
Philips has issued a voluntary recall for specific Philips Respironics CPAP, bilevel PAP, and mechanical ventilator devices. The recalled machines include the DreamStation devices that are used to treat obstructive sleep apnea. (The newer DreamStation 2 is not affected.) Philips has begun a process to repair and replace affected devices. How long this process will take is unclear.
The recall is related to the type of foam used to reduce the noise made by the devices. Over time, the foam inside the machine may fall apart into black particles. These particles can enter the humidifier, tubing and mask. As a result, you may inhale the particles when using the device. Testing by Philips also found that the foam can produce unsafe chemical levels. These “volatile organic compounds” are released as gases.
Philips reports that the potential risks to you include:
Philips reports that in 2020 the complaint rate for foam particles was low (0.03%). To date, there have been no reports of death. Philips has received no complaints related to chemical exposure.
