Trilogy 100 ventilators have been recalled due to a manufacturing issue. This issue can cause part of the blower that circulates air and other gases through the ventilator to move out of position and cause the device to alarm and stop delivering therapy to the patient. In the event of a blower failure, the ventilator will stop delivering therapy and a high priority alarm will sound to alert the caregiver to immediately respond. Failure to respond could result in the potential for harm or death of a ventilator-dependent patient.
