Philips CPAP Lawsuit Facts
TorHoerman Law is no longer accepting claims for the Philips CPAP Lawsuit.
Intake Closed
Philips CPAP machines and other recalled devices have been identified as potential sources of liver cancer due to the emission of volatile organic compounds (VOCs) as sound abatement foam breaks down.
Potential carcinogens identified from the degradation of the sound abatement foam include:
- TDA (toluene diamine): TDA is a chemical that can be released during the breakdown of polyurethane foams; it is known for its use in the manufacture of polyurethane and other chemicals, potentially leading to respiratory issues and skin irritation when inhaled.
- TDI (toluene diisocyanate): TDI is commonly used in the production of flexible polyurethane foams, which can off-gas from degrading foam in CPAP devices, causing severe respiratory problems and is a known carcinogen.
- DEG (diethylene glycol): This compound may be emitted from breakdown products of foam adhesives and sealants used in manufacturing CPAP devices; DEG exposure is toxic to humans, potentially causing kidney and neurological damage.
- DCM (dichloromethane): Often used as a solvent in the production of plastics and pharmaceuticals, DCM can be released from the breakdown of foam components in CPAP devices and is associated with cancer and central nervous system effects.
Chronic exposure to these carcinogens may lead to the accumulation of toxic substances in the liver, increasing the risk of liver cancer.
Do Philips Respironics Ventilator, CPAP, and BiPAP Devices Cause Cancer?
Researchers are currently investigating the association between the use of Philips CPAP machines, BiPAP machines, and Ventilator devices and cancer incidence in patients with obstructive sleep apnea.
Assessing the cancer risk associated with the use of recalled Philips CPAP devices is challenging due to the recent nature of the recall and the complexity of linking specific device defects to health outcomes, particularly when considering the long latency periods typical of many cancers.
Scientific research faces difficulties in isolating the effects of volatile organic compounds emitted by the defective foam, as these studies require long-term data and robust methodologies to accurately discern and attribute risks.
Regardless, scientists and health professionals are concerned about the presence of harmful substances and foam particles in the defective nature of these devices, as certain VOCs found to emit from the recalled Philips CPAP machines have been linked to carcinogenic effects.
The study “Cancer Risk Associated with Continuous Positive Airway Pressure: A National Study” (2022) analyzed data from the MAUDE database following a 2021 FDA recall of CPAP devices due to potential cancer risks from degraded sound abatement foam, revealing that of 2571 reported injuries, 209 were cancer cases, with the vast majority reported after the recall.
A February 2024 report from the US Food and Drug Administration (FDA) showed that the MAUDE database has received more than 116,000 medical device reports of foam breaking down in Philips CPAP machines.
The FDA says now that 561 deaths are now linked to recalled Philips sleep apnea machines.
The development of cancer after using recalled CPAP machine is hotly debated, and more scientific research is needed to understand the full scope of potential health risks associated with exposure to volatile organic compounds and other byproducts released from the degrading polyurethane foam used in these devices.
VOCs in Recalled Philips CPAP Machines Linked to Health Problems
The VOCs found in the emissions of the recalled CPAP devices, including TDA (toluene diamine), TDI (toluene diisocyanate), DEG (diethylene glycol), DCM (dichloromethane), and others, may be linked to carcinogenic effects through various mechanisms.
TDA is a compound used in the production of polyurethane foam that has been associated with cancer based on animal studies, prompting concerns about its potential carcinogenicity in humans, although direct epidemiological evidence in humans is lacking.
TDI, another constituent of polyurethane foam, has been identified as a potential carcinogen, particularly in occupational settings where prolonged exposure increases the risk of respiratory cancers such as lung cancer.
DEG, commonly used as a solvent in various industries, has been linked to liver damage and kidney injuries, as it can potentially disrupt cellular processes and induce oxidative stress.
DCM, a solvent present in the foam, has been classified as a probable human carcinogen by the International Agency for Research on Cancer (IARC), with evidence suggesting its involvement in liver and lung cancers through metabolic activation and genotoxicity.
Collectively, VOCs from the recalled CPAP devices may pose a significant health risk.
