Philips has issued a recall notification for a large number of their CPAP and Bilevel PAP machines.
Based on testing, Philips has determined that the type of foam used in these devices may degrade into particles which may enter a person’s airway and be ingested or inhaled into the lungs.
In accordance with recommendations from Philips and the American Academy of Sleep Medicine, we are advising patients to STOP using any affected Philips machine or device.
Please contact your CPAP equipment company and insurance company about receiving a replacement unit as soon as possible.
While waiting for your replacement unit, it is recommended that you sleep in an upright or semi-upright “recliner” position at night to reduce sleep apnea.

“Even before I entered the field of medicine, it was my personal mission to make a difference in people’s lives. Over the years, I have had the opportunity to work in a homeless shelter, as well as spend time in Africa providing humanitarian aid.
As I progressed through my medical education, I became aware of just how crucial sleep is to a person’s physical and mental well-being. That is why I chose to pursue this profession. Being in sleep medicine gives me an opportunity to make a deep and positive impact in people’s lives.” — Dr. Richard L. Cho
