Philips CPAP Lawsuit

Philips CPAP Lawsuit

In June of 2021, Philips Respironics announced a recall for sleep apnea machine models that may increase the risk of developing lung cancer, kidney cancer, liver cancer, and other forms of cancer. The affected products include continuous positive airway pressure (CPAP) machines, Bilevel positive airway pressure (BiPAP) machines, and mechanical ventilators designed to help people with breathing disorders, including sleep apnea. The U.S. Food and Drug Administration (FDA) identified the Philips Respironics recall as the agency’s most serious (Class I).

The Philips recall affects millions of people who rely on these machines to help them with breathing disorders. According to Philips, roughly 80% of the affected products are CPAP machines for people with sleep apnea. Shocked by the news that these products may be linked to cancer and a host of other serious health issues, many are turning to the courts to seek damages against Philips for putting a defective and dangerous product on the market.

What Caused the Philips CPAP Recall?

Philips Respironics cited a serious problem with the polyester-based polyurethane foam that dampens the sound and vibration when the machines are in use. The foam can break down and release small chemical particles into the machine’s airway, which can then be inhaled or ingested. According to the FDA, particulate exposure from Philips sleep apnea machines may have “toxic or carcinogenic effects to organs, such as kidneys and liver.”

CPAP Class Action Lawyers

If you or someone in your family developed cancer after using any of the Philips Respironics CPAP machines, BiPAP machines, or ventilators listed below, you may be eligible to pursue justice and compensation in a lawsuit against the manufacturer. CPAP lawyers represent victims on a contingency fee basis, which means the attorneys only get paid if your case ends in a successful verdict or settlement. If for some reason the litigation does not result in compensation, you would not owe anything.

Why Are CPAP Sleep Apnea Machines Recalled?

Philips determined a recall was appropriate after receiving user reports and conducting lab testing on several CPAP, BiPAP, and ventilators, including the widely-used Philips DreamStation. The company found that the polyester-based polyurethane (PE-PUR) sound abatement foam used in Philips sleep machines can degrade and deteriorate over time, which can cause people who rely on these machines for breathing assistance to inhale or ingest small particles or gas.

Inhaling or ingesting PE-PUR particulate can cause a host of health issues. Philips has already acknowledged that the risks of particulate exposure include:

  • Adverse effects to kidneys and liver
  • Asthma
  • Headache
  • Inflammatory response
  • Irritation (eye, respiratory tract, and skin)
  • Respiratory issues
  • Toxic carcinogenic effects

According to Philips, the foam degradation may worsen in certain conditions, including higher temperatures and humidity, and the use of unapproved cleaning methods (including ozone).

Class-Action Lawsuit Alleges Philips Knew for Years That CPAP Machines Were Dangerous

Shortly after the FDA CPAP recall, a class-action lawsuit was filed alleging Philips knew that its CPAP machines were dangerous years before the company decided to issue its recall. The class-action alleges that numerous people had complained to Philips in the years before the recall noting that they found “black particles” in their sleep machines, including the company’s flagship DreamStation line of CPAP machines.

Rather than issuing a warning to consumers, the class-action lawsuit alleges that Philips continued to sell its line of CPAP, BiPAP, and ventilators until it could launch a new generation of CPAP, BiPAP, and ventilator machines to replace the recalled machines. Considering how many people rely on these machines each and every day, our law firm is appalled by Phillips’ alleged actions.

CPAP Lawsuit FAQ

What is a CPAP Machine?

CPAP (continuous positive airway pressure) machines are medical devices used to treat people with obstructive sleep apnea. CPAP sleep machines send a steady flow of oxygen to the nose and mouth, keeping the airway open and allowing the patient to breathe normally. CPAP machines have motors that generate oxygen, which travels through a filter and a flexible tube before reaching the mask, sealed around the patient’s nose and mouth.

What is the Difference Between CPAP and BiPAP?

They may look similar, but BiPAP (bilateral positive airway pressure) machines differ from CPAP machines. BiPAP machines are more complex than CPAP machines in that they have two pressures (inhalation and exhalation) compared to the CPAP’s one pressure. BiPAP therapy is the preferred treatment method for people who do not respond to CPAP therapy, including those with central sleep apnea, complex sleep apnea, or chronic obstructive pulmonary disease (COPD). BiPAP machines are generally more expensive than CPAP machines, so many people who can be treated by either choose CPAP instead of BiPAP.

What is Sleep Apnea?

Sleep apnea is a serious sleeping disorder where a person’s breathing repeatedly starts and stops. It is the most common sleeping disorder in the U.S.

There are three types of sleep apnea:

  • Obstructive Sleep Apnea – Obstructive sleep apnea happens when an individual’s throat muscles intermittently relax, blocking the airway during sleep. It is the most common type of sleep apnea, affecting an estimated one in 15 people in the U.S.
  • Central Sleep Apnea – Central sleep apnea happens when an individual’s brain does not send the proper messages to the muscles that control breathing. This study estimates that .9% of people over 40 have central sleep apnea.
  • Complex Sleep Apnea Syndrome – Complex sleep apnea, also known as treatment-emergent central sleep apnea, occurs when a person presents with both obstructive sleep apnea and central sleep apnea.

How Do Philips Breathing Machines Cause Cancer?

The polyester-based polyurethane foam used in the recalled Philips breathing machines may degrade over time. This degradation may allow particles to flow into the affected CPAP, BiPAP, and ventilator air pathways, which then causes the person using the device to breathe in the particles. As Philips said in its clinical information, the “absence of visible particles does not mean that foam breakdown has not already begun.” This means that even if you can’t see foam degradation on your sleeping machine, you still may be inhaling toxic particles. Philips has already admitted the presence of the following:

  • Toluene Diamine: According to the U.S. Environmental Protection Agency (EPA), in animal studies, toluene-2,4-diamine was found to be a carcinogen following dietary administration. EPA noted a significant increase in the incidence of a many different tumor types, including liver, mammary gland, subcutaneous fibromas, lung lymphomas, and leukemia.
  • Toluene Diisocyanate (TDI): The International Agency for Research on Cancer (IARC), the gold standard for carcinogenicity testing, classifies TDI as a possible human carcinogen. IARC came to its conclusion based on sufficient evidence in experimental animals and inadequate evidence in humans. This study notes that TDI is a “well-known sensitizer and cause of occupational asthma.”
  • Diethylene Glycol: Associated with renal failure (acute kidney injury).
  • Dimethyl Diazene: Also known as azomethane. The oxide derivative of this compound is azoxymethane, a known carcinogen.
  • Phenol, 2,6-bis (1,1-dimethylethyl)-4-(1-methylpropyl): According to EPA, Phenol is considered toxic to humans via oral exposure. Anorexia, a dark coloration of the urine, diarrhea, progressive weight loss, salivation, vertigo, and blood and liver effects have been reported in chronically (long-term) exposed humans. Animal studies have shown reduced fetal body weights, growth retardation, and abnormal development in the offspring among animals exposed to phenol by the oral route.
