Philips Respironics Trilogy Evo O2 ventilator recalled for delayed obstruction alarm

OTHERNationwide distribution

Check your Philips Respironics ventilator settings

Some Philips Respironics Trilogy Evo O2 ventilators with software version 1.05.15.00 may not sound an obstruction alarm quickly enough if the breathing tube becomes blocked. The alarm could be delayed by up to four breaths, which could reduce the time available to respond to a blockage.

  • If you use this ventilator, contact Philips Respironics immediately for instructions or a software update
  • Verify your device model number and software version match the recall details
  • Continue using your ventilator but monitor the obstruction alarm function closely
  • Ask your respiratory therapist or home care provider to check your device
Hazard

In some situations, the Obstruction Alarm does not trigger within the timeframe dictated by the relevant standards and may take up to four breaths.
