Philips has launched a recall of some of its mechanical ventilation, two-level positive airway pressure (PPB) and continuous positive airway pressure (CPAP) devices. After testing, and despite a low complaint rate (0.03% in 2020), Philips determined that the polyester-based polyurethane (PE-PUR) soundproofing foam component of these devices would indeed exhibit potential risks to the health of users. A decision all the more important as the brand’s Connected Care division provides the equipment necessary to treat patients with Covid-19, such as breathing apparatus.
FOAM THAT COULD DEGRADE
The risks include the degradation of the PE-PUR foam into particles which can enter the air circuit of the device and be ingested or inhaled by the user, as well as the gassing of certain chemicals.
The noise-canceling foam used in some of its sleep and respiratory care devices could degrade when poorly cleaned or when used in hot and humid conditions.
WE ARE WORKING HARD TO FIND A SOLUTION
In consultation with relevant regulatory authorities and in close collaboration with our customers and partners, we are working hard to find a solution, which includes the deployment of updated operating instructions and a comprehensive device repair and replacement program.
We have seen a very low incident rate, said the manager. But as a precaution, we think we need to take action and fix the affected machines and change this component.
