Philips’ ventilator woes grow as FDA issues alert over replacement foam

Philips has found new potential issues with the Respironics Trilogy ventilators that it reworked as part of a recall that began last summer.
According to the Food and Drug Administration, the silicone sound abatement foam installed to replace the polyester-based polyurethane (PE-PUR) foam can block the air inlet and trace amounts of particulate matter have been found in the air pathway.
