Update 11/17/22 – Philips Trilogy Ventilators
Certain Trilogy ventilators that were repaired due to the earlier recalls are being recalled again due to two new potential problems. One issue is the reworked machines may have trace amounts of polyester-based polyurethane (PE-PUR) foam or other particles in the air delivery portions of the device. The other issue is that the sound abatement foam used to correct issues from the earlier recall, may come loose and block the air inlet. This blockage could cause a Low Inspiratory Pressure alarm.
If you have one of these restored devices, please visit the U.S. Food and Drug Administration (FDA) website for more information, and consult with your physician.
