At the time the field safety notice was issued, Philips Respironics relied on an initial, limited data set and toxicological risk assessment. Out of an abundance of caution, a reasonable worst-case scenario was considered. At the time, Philips Respironics could not exclude possible carcinogenic effects with the limited dataset that was available. Philips Respironics did not have conclusive data indicating that exposure to the particulates or emitted chemicals would lead to cancer.
Since then, together with five independent, certified testing laboratories in the US and Europe and other qualified third-party experts, Philips Respironics has been conducting a comprehensive test and research program on the PE-PUR foam to better assess and scope the potential patient health risks related to possible emission of particulates from degraded foam and volatile organic compounds. This also includes an in-depth review and re-assessment of data and toxicological risk-assessments prior to June 2021.
This Philips Respironics December 2022 update is intended to provide healthcare providers, patients, and other stakeholders with updated information on the testing results and third party confirmed conclusions to date on results and findings from testing PE-PUR foam used in recalled devices for VOCs, particulate matter (PM), and other testing such that healthcare providers have additional information to make informed decisions regarding the risk of continued use of recalled products.
