Philips issued a voluntary recall for millions of its sleep apnea machines and life-sustaining ventilators after it found that foam used in the breathing devices may degrade into particles and be ingested or inhaled by users. The foam may also give off chemical emissions. Exposure to foam particles or emissions is potentially toxic, the manufacturer said, and may cause cancer, among other health risks.
The recall involves an estimated 3 million to 4 million devices globally, based on the company's production and shipment data. Over half of the devices were sold in the U.S., with the majority of them being the first-generation DreamStation products. DreamStation 2 products are not affected by the recall.
Philips has not received reports of deaths, but it is aware of consumers finding black debris within the air-path tube and feeling sick. Potential risks from exposure to the foam include headache, irritation, inflammation, respiratory issues, and possible toxic and carcinogenic effects. Risks from chemical exposure include headache, irritation, hypersensitivity, nausea/vomiting, and possible toxic and carcinogenic effects. The company hasn't received reports about patient exposure to chemical emissions.

The specific Philips Bi-Level Positive Airway Pressure (Bi-Level PAP), Continuous Positive Airway Pressure (CPAP) and mechanical ventilator devices that were recalled are listed by the company here with steps for consumers to take.
"In consultation with the relevant regulatory agencies and in close collaboration with our customers and partners, we are working hard towards a resolution, which includes the deployment of the updated instructions for use and a comprehensive repair and replacement program for the affected devices,” said Philips CEO Frans van Houten. The company is sending letters to users with instructions for registering online to have affected devices repaired or replaced. Anyone who doesn't receive a letter should call Philips at 877-907-7508.
Those with affected PAP and CPAP devices should discontinue using them and work with their provider to determine the best option for continued treatment. Patients using life-sustaining mechanical ventilators should not stop using the devices before talking to a doctor about alternative options.
Sleep apnea in older adults
Sleep apnea is a common condition in the U.S. that occurs when the upper airway becomes blocked during sleep, reducing or stopping airflow. The majority of those affected with sleep apnea remain undiagnosed. A mechanical device such as a CPAP machine can be used to treat sleep apnea by pumping air through a tube into a mask worn by a person with sleep apnea.
The risk for sleep apnea increases as you get older. Sleep apnea may affect between 38 percent and 68 percent of people over 60, a study from the Centers for Disease Control and Prevention (CDC) found. According to the National Institutes of Health (NIH), normal age-related changes in how the brain controls breathing during sleep partially explain the increased risk with age. Another reason may be that more fatty tissue builds up in the neck and tongue as we get older.
Other causes of sleep apnea include obesity, large tonsils, endocrine disorders, neuromuscular disorders, heart or kidney failure, genetics, and premature birth.
