Philips Respironics Recalls Millions of CPAP Machines

The U.S. Food and Drug Administration (FDA) issued a recall notice concerning several Philips Respironics CPAP machines in June 2021. Philips manufactured the problematic devices between 2009 and April 26, 2021, before issuing a voluntary recall for its widely-used medical devices that assist patients with complications of sleep apnea and other conditions causing breathing issues throughout the night.

The continuous positive airway pressure (CPAP) machines create a channel of forced air to keep airways open when sleeping. Most CPAP users have obstructive sleep apnea. However, researchers found that a sound-deadening foam in the machines used to silence its loud vibrations would break down, releasing harmful chemicals into users' airways. Prolonged exposure to these chemicals can cause lung cancer and other health conditions.

What Is Sleep Apnea?

Sleep apnea is a condition that interferes with nighttime breathing. It can be either obstructive sleep apnea (the most common type), occurring when the throat muscles relax, narrowing or closing off your airway, or central sleep apnea, resulting from improper or a lack of signals from the brain to the muscles that control breathing. In some instances, patients can suffer from both types.

Patients afflicted by this sleep disorder stop breathing several times each night. You might wake up suddenly several times during the night and repeatedly gasp for air, or you might simply have trouble staying asleep. Morning headaches and dry mouth are also sometimes indicative of improper breathing during sleep. If you snore loudly or regularly feel tired after a full night's sleep, you might have sleep apnea.

It's important to speak with your doctor about possible sleep disorders if you suffer from any signs or symptoms of disrupted or inadequate sleep. Sleep apnea can be a potentially serious and dangerous condition. Complications of untreated sleep apnea include:

  • High blood pressure
  • Glaucoma
  • Heart and cardiovascular problems, including heart attack
  • Cancer
  • Type 2 diabetes
  • Metabolic disorders affecting weight, cholesterol, blood pressure, and blood sugar levels
  • Cognitive impairment, affecting your ability to drive (e.g., drowsy driving) or perform other routine tasks
  • Behavioral disorders
  • Medication and general anesthesia complications (your health care providers may need to take extra precautions during surgery)
  • Liver problems
  • Sleep deprivation for you and your family

CPAP machines are a popular treatment for sleep apnea. These medical devices release air pressure into the sleeper's nose, gently forcing their passages open to keep oxygen moving through the airways and into the lungs to provide adequate rest.

side effects of exposure to pe-pur

Common side effects of CPAP machine usage include dry mouth and eyes, congestion or runny nose, and nosebleeds. If you experience more severe side effects, such as stomach discomfort, bloating, or anything else unusual, you should discontinue use and contact your doctor immediately. Never alter your treatment regimen without consulting with your doctor.

What is Polyester-Based Polyurethane (PE-PUR) Sound Abatement Foam?

The use of polyester-based polyurethane (PE-PUR) sound abatement foam in many home and industrial devices is common. It essentially acts as a replacement for rubber and helps to insulate or provide a "cushion" in many products. Likewise, Philips Respironics used this type of foam in its CPAP machines to reduce noise and vibrations made by the device.

However, recently, researchers found PE-PUR can cause health risks and lead to long-term health issues. The science behind the potential health risks to patients hinges on a design flaw that can lead to foam degradation, resulting in black particles entering the air tube, which users unknowingly inhale or ingest. Researchers have found these particles and other gasses released during the degradation of silicone, this particular foam to be potentially toxic. It may even possibly contribute to various cancers due to additives such as flame retardants.

Additionally, researchers have linked isocyanates used in PE-PUR manufacturing to severe respiratory problems, including shortness of breath, pneumonia, life-threatening asthma, pulmonary fibrosis, and bronchitis. The damage to the lungs can be permanent, with cancer and other health complications also apparent.

What is the off-gassing of diethylene glycol (DEG)?

As the foam in the recalled Philips CPAP devices ages, it releases Volatile Organic Compounds (VOCs). VOCs are chemicals released from many plastics and other human-made compounds. As chemists and doctors study these materials, they've found both short- and long-term adverse health effects associated with their use and human exposure.

Diethylene glycol (DEG) is one chemical off-gassing from the PE-PUR foam previously used in Philips Respironics CPAP machines, as it degrades. It's a highly toxic chemical with exposure likely to cause many health problems in individuals, ranging from nausea and vomiting to coma and death.

Side Effects of Exposure to PE-PUR Sound Abatement Foam

The consequences can be severe, permanent, or deadly when patients breathe in the chemicals or swallow the broken down particles from degraded polyester-based polyurethane (PE-PUR) sound abatement foam in Philips CPAP machines. The risk of foam degradation is higher when high heat and humidity is present, and when the device is cleaned improperly.

In its June 2021 recall notice, the FDA noted several complaints from users received by Philips Respironics, citing "reports of headache, upper airway irritation, cough, chest pressure, and sinus infection." These symptoms began after patients became aware of black particles and debris in the devices' air pathways.

Dangers of exposure to these particles and chemicals released into the device's airways from PE-PUR foam degradation include:

  • Headache
  • Dizziness
  • Irritation to the skin and in the eyes, nose, and respiratory tract
  • Hypersensitivity or inflammatory response
  • Nausea
  • Vomiting
  • Asthma
  • Toxic or carcinogenic effects to the organs, such as the kidneys and liver
Dangers of Silicone-Based Replacement for the PE-PUR Foam

Philips is replacing the PE-PUR foam used in its CPAP devices with silicone-based foam. The silicone product also off-gasses volatile organic compounds (VOCs). These gas emissions can cause short and long-term health complications that mirror those seen with particulate and chemical exposure from PE-PUR foam degradation.

After conducting its own testing, Philips said the product was safe, thereby gaining FDA approval for the replacement foam. However, during the manufacturing facility inspection, FDA officials became aware of information not previously made available about possible safety issues with the new sound-abatement material. A singular, similar device manufactured outside the United States, containing the same silicone-based product, failed a safety test for VOCs, exposing a potential weakness in the replacement CPAP machines that could cause similar problems for patients injured by the PE-PUR foam.

The FDA is aware that many patients are already using the replacement devices containing the silicone-based foam and doesn't have enough information at this time to conclude the risks associated with the same. The federal agency is requiring Philips Respironics to conduct further testing at an independent laboratory to confirm the replacement foam's safety.

Until such a time as the FDA releases data regarding the additional evaluation of the product, there's no recommendation to discontinue the use of the replacement CPAP or other ventilator machines. Patients should follow the advice of their health care team about the best course of action that aligns with their individual treatment plans.

What to Do if You Have Been Using the Recalled CPAP Machines

The FDA recommends you stop using the affected machines immediately. Visit your doctor and find a different CPAP or ventilator device to use or discuss alternative treatment options if relevant to your medical care plan.

Philips has announced that it will take back all the affected devices to repair or replace them. Talk to your doctor about the best course of action for you.

What if My Doctor Deems It Necessary to Continue Using a CPAP Machine?

Continue using your CPAP device until you receive a replacement or alternative treatment plan if your health care provider determines that the benefits outweigh the risks identified in the recall notification. Never stop or change your course of treatment without first speaking with your doctor. If you continue to use your machine, don't use ozone cleaners and avoid storing it in high heat or humid environments. The FDA has issued a warning that these cleaners and environmental conditions can break down the foam at a faster rate.

You can get an inline bacterial filter to catch the small particles. This filter will not catch the outgassing chemicals and needs regular inspections. Talk to your doctor about other precautions.

What Do I Do if My CPAP Machine Is Part of the Recall?

Register your device with Philips Respironics by phone at 877-907-7508 or online. Visit your doctor if you're experiencing any signs or symptoms of particulate or chemical exposure from PE-PUR sound-abatement foam degradation. You should also contact an attorney to discuss possible compensation for your injuries.

How Does “Repair and Replace” Work?

After you register your CPAP or another device on the Philips Respironics Device Recall Notification website, Philips will tell you how to send in your device for repair or replacement. For some customers, Philips will send a repair kit and a payment for the hourly wage of repairing it. Replacement and repair may take up to one year. Talk to your doctor about finding replacement respiratory care devices so that you can continue your recommended or required treatment.

Report Your Side Effects Using an FDA Medwatch Voluntary Report Form

If you experience particulate or chemical exposure symptoms or suffer other injuries after using a Philips Respironics CPAP device, use the FDA's MedWatch Voluntary Reporting form to let the agency know what you're experiencing. Voluntary reporting helps the FDA track unknown risks for approved health care devices and medications. Your doctor or other health care provider can also report problems with your device to the regulatory agency using a separate form.

Alternatives to Sleep Apnea CPAP Treatment

There are several alternatives to using a CPAP machine to treat sleep apnea. It's important to seek medical advice from your doctor or other health care provider before changing your treatment.

Examples of sleep apnea treatment alternatives include:

  • A device that warns when you move into a dangerous position that can impair your breathing
  • Devices that hold the airways in your nose open to allow for adequate, continuous airflow
  • An oral appliance that places your mouth and tongue better to prevent obstructions from relaxed throat muscles
  • Nerve and tongue stimulation
Recent Update to the Philips Recall

In October 2021, a person suing Philips for the harms caused by its CPAP and other mechanical ventilator devices registered a class-action product liability lawsuit in Pennsylvania. Also that month, SoClean, Inc. filed a lawsuit against Philips Respironics for false and misleading statements. In November 2021, "following further assessment of the issue, and discussions with regulatory agencies," Philips updated its recall notice.

Philips knew about the problem with the PE-PUR foam since 2016. The company failed to warn consumers and health care providers and chose to do nothing to correct the problem until FDA inspectors became aware of it. Philips received over 222,000 complaints that included the keywords "contaminants, particles, foam, debris, airway, particulate, airpath, and black."

Process to File a Claim for Patients Affected by Philips' Recalled CPAP Devices

Contact an attorney and seek legal advice if you've suffered harm after using a Philips CPAP machine. An attorney can explain your rights, determine if you have a valid case, and help you decide what your next steps should be. The PE-PUR used in Philips CPAP and other mechanical ventilator devices can cause serious injuries, and it's important that the responsible parties are held accountable and that you get the compensation you need to aid in your recovery.

Lawsuits are still in the early phases. Several individuals have filed lawsuits in federal courts, and many are joining together in multidistrict litigation. Nearly 140 injured patients are seeking financial compensation for harms caused by Philips sleep apnea devices and mechanical ventilators in a Pennsylvania court (MDL-3014).
