The number of people impacted by a defective CPAP machine to combat their sleep apnea continues to grow. There have been more than 90,000 reports about problems with the devices, including 260 reports of people who died—all since April 2021. The FDA is now conducting an in-depth review into why these numbers have spiked in the last year and a half. Our attorneys understand that you expected your medical device to work properly and not cause more serious health problems. It is time for you to take action and get the compensation you deserve for your serious injuries.

Health Conditions Caused by Foam

Philips Respironics issued a recall last summer because the machines manufactured between 2009 to June 2021 were defective. The machines used soundproofing foam, but as the PE-PUR foam degraded over time, more than five million people who used these CPAP, BiPAP, or ventilator machines may have been exposed to harmful particles while breathing.

The reports filed by Philips Respironics to the FDA included mandatory reports from Philips and voluntary reports from health professionals and consumers. They mention serious health injuries including various forms of cancer, pneumonia, asthma, infection, headache, cough, difficulty breathing, dizziness, nodules, and chest pain.

CPAP machines are a common treatment for sleep apnea, but some models have been recalled due to defects that may pose a health risk. The recalled devices used a synthetic foam composed of polyester and polyurethane that was meant to reduce the noise when a device was operating. Unfortunately, this foam, which is toxic to humans, could break down during a device's regular use. As air passed through a device and was forced into a user's lungs, it may have picked up particles of foam, which could then be inhaled or swallowed by the user. This could potentially lead to a variety of health issues, including an increased risk of kidney cancer.

Symptoms of Kidney Cancer

The absorption of tiny foam particles into the bloodstream may affect multiple organs and bodily systems. Because the kidneys act as a filter for the blood, foam particles may have accumulated in the kidneys and affected the organ's tissues. This may have led tumors to form, affecting kidney functions. As tumors grow, they may also affect other bodily systems, including spreading to nearby lymph nodes, major blood vessels, or the adrenal gland. In the most serious cases, cancer may metastasize throughout the body, affecting distant lymph nodes or other organs.

If a person has kidney cancer, they may experience the following symptoms:

Sleep apnea, in which a person periodically stops breathing while they are sleeping, can seriously affect the quality of a person's sleep and their overall health. While multiple forms of treatment are available to address this issue, the most effective treatment for most people is to use a CPAP machine. These devices force air into a person’s nose or mouth while they are sleeping, keeping their airways open and ensuring that they do not stop breathing. Unfortunately, many people have lost their access to this form of treatment due to a recall of CPAP machines by a major medical product manufacturer. Due to this recall, people may not only need to deal with the loss of treatment, but they may also have been placed at risk of injury due to toxic materials in the recalled devices. There are a number of injuries and illnesses that may have affected CPAP users, including liver cancer.

Signs and Symptoms of Liver Cancer for CPAP Users

The recalled CPAP machines were found to be dangerous due to a foam that had been used to reduce noise while the devices were operating. This foam, which was composed of polyester-based polyurethane, could break down over the lifetime of a device, and users may have inhaled particles of this toxic substance, as well as dangerous chemicals.

Toluene diisocyanate is one chemical that has been found to be released when the foam in defective CPAPs degrades. This substance has been classified as a possible human carcinogen by the International Agency for Research on Cancer (IARC), and it has been found to cause liver cancer and other forms of cancer in lab animals that had been exposed to the chemical. 

Many people use continuous positive airway pressure (CPAP) devices to treat sleep apnea or similar conditions. CPAP machines provide a steady stream of air that keep a person’s airways open, ensuring that they do not stop breathing while they are sleeping. These devices can provide numerous benefits, including helping people avoid the risks of heart conditions, ensuring that they get enough rest while sleeping, and improving their overall health. 

Unfortunately, a large number of CPAP users have learned that the products that were meant to benefit them may have put them at risk of injury. A massive recall of CPAP machines is currently being performed by Philips Respironics. The recalled devices contained a type of foam composed of polyester-based polyurethane, and the breakdown of this foam over time may have led foam particles and hazardous chemicals to be inhaled by users. These substances have been associated with multiple forms of cancer, including throat cancer and esophageal cancer.

Throat Cancer Symptoms and Treatment

Cancers of the throat may affect the windpipe, the voice box and vocal cords, the pharynx (the passage connecting the back of the nose to the beginning of the windpipe), the tonsils, or other parts of the head and neck. Tumors may form in the cells lining the throat, and they can result in symptoms such as difficulty swallowing, sore throat, persistent coughing, swollen lymph nodes in the neck, hoarseness when speaking, pain in the ears, weight loss, and wheezing or other breathing problems.

Since the medical equipment manufacturer Philips Respironics began recalling millions of CPAP and BiPAP machines and ventilators in 2021, users of these devices have been concerned about the potential health risks that may have affected them. The recalled devices contained a polyurethane foam that could break down during regular, daily use, and the inhalation of particles and chemicals may have led to multiple types of health issues. By understanding the specific substances that people may have been exposed to and their potential effects, CPAP users can determine whether they have suffered harm, and they can work with an attorney to determine their legal options.

Potentially Harmful Chemicals That May Affect CPAP Users

Testing performed by Philips determined that the breakdown of the foam used in CPAP machines and other devices may have caused users to inhale small foam particles. These particles contained multiple types of toxic chemicals, including:

• Toluene diamide - This chemical can cause irritation of the nose and throat, as well as skin conditions such as dermatitis. It can also cause nausea and vomiting, respiratory depression, headaches, weakness/fatigue, dizziness, convulsions, loss of muscle coordination, blood disorders, or damage to the liver. A person may experience cyanosis, or a bluish color in their skin, due to decreased amounts of oxygen in the blood. The chemical has also been associated with cancer affecting the liver, skin, and breasts.
