Philips CPAP and BiPAP Devices Recalled Over Potential Cancer Risk

Philips CPAP and BiPAP Devices Recalled Over Potential Cancer Risk Phillips Respironics has issued a voluntary recall of its continuous positive airway pressure (CPAP), bilevel positive airway pressure (BiPAP) and ventilator devices over a potential risk of users inhaling carcinogenic materials. The recall affects more than 3.5 million devices manufactured between 2009 and April 2021.

What makes Philips’ CPAP, BiPAP, and ventilators dangerous?

There are two risks associated with the recall.

Inhalation and ingestion risk

Each CPAP, BiPAP, and ventilator device contains a polyester-based polyurethane (PE-PUR) sound abatement foam within it. This foam helps to reduce the noise of the motor of the affected devices. In some cases, the foam can degrade, and bits of it can break off and travel through the air tube attached to the affected devices. Users could swallow or inhale the foam.

Noxious chemical risk

Per Philips, “PE-PUR foam may off-gas certain chemicals. The foam degradation may be exacerbated by use of unapproved cleaning methods, such as ozone, and off-gassing may occur during operation.” Off-gassing refers to the “emission of especially noxious gasses.”

What are the potential health complications associated with defective Philips CPAP, BiPAP and ventilator devices?

In the best-case scenarios, users who inhale bits of particulate foam may suffer from irritation of the respiratory tract, coughing, headaches, and nausea. In the worst-case scenarios, inhalation, ingestion, and exposure to toxic gases can lead to:

  • Inflammatory responses
  • Asthma
  • Adverse effects on the liver, lungs, and kidneys
  • Hypersensitivity
  • Increased risk of cancer

The degradation of the PE-PUR foam can lead to “possible toxic and carcinogenic effects” on a user, either through the inhalation or ingestion of particulates, or though exposure to toxic gases.

To date, Philips has not received any reports of toxic off-gassing, and no deaths have been reported.

Which defective Phillips devices were recalled?

Phillips has recalled certain models of CPAP, BiPAP, and ventilator devices. The ventilators are not the same type of ventilators we typically associate with hospitals, but healthcare facilities, including hospitals, nursing homes, rehabs, Emergency Services and surgical centers may use these devices as well. Per the Food & Drug Administration (FDA), the following devices are subject to recall:

What should I do if I own a recalled device?

Contact your doctor immediately to learn if you should discontinue use of your machine. If your loved one is using a life-sustaining ventilator device, stopping use could be life-threatening.

You can request a new device or new sound abatement foam (made from a different chemical) from Philips, but do not throw out or return your device to the company without consulting an attorney first. In order to make an effective claim for damages, you will need the original device.

Can I file a lawsuit against Philips related to its defective CPAP, BiPAP, and ventilator devices?

Potentially, yes. Arizona requires that consumers who bring product liability lawsuits against companies prove they were exposed to unreasonable risk, under the Economic Loss Doctrine. You cannot bring a lawsuit for damages if all you seek are economic damages. You must be able to prove that you were at risk of, or sustained, an injury or illness from the device.

Further, you must show that you were not to blame for your own injuries, or you could be barred from recovering compensation at all.
