Philips Respironics is recalling 113,717 Trilogy Evo, Trilogy Evo O2, Trilogy EV300, and Trilogy Evo Universal ventilators because the Obstruction Alarm may not trigger within the required timeframe. In some cases, it can take up to four breaths for the device to notify a user of a blockage. These devices are continuous home-use ventilators used to provide respiratory support for patients. No injuries have been reported, but a delay in alarming for a blocked airway could lead to serious respiratory distress.
The software error prevents the obstruction alarm from firing immediately, potentially delaying medical intervention during a critical airway blockage. This could result in decreased oxygen levels or other life-threatening complications for patients dependent on the device.
