Philips Respironics has become aware of a potential issue when using in-line nebulizers in certain configurations with Trilogy Evo, Trilogy Evo O2, Trilogy Universal (US) and Trilogy EV300 devices. The use of in-line nebulizers placed in certain locations can result in aerosol deposits accumulating over time on the device’s internal flow sensor. Impacted flow sensors may result in inaccurate flow measurements in certain circumstances.
Nebulized aerosols have the potential to permanently impact the internal flow sensor. Any Trilogy Evo, Trilogy Evo O2, Trilogy Universal (US) and Trilogy EV300 device that have historically been used with an in-line nebulizer may be impacted. If your device has never been used with an in-line nebulizer, it is not affected by this issue and can continue to be used in accordance with the guidance within the FSN.
