ANSM issued a safety alert (Ref. R2604745) requiring Philips Respironics Trilogy Evo, Trilogy Evo O2, and Trilogy EV300 ventilators to receive mandatory software updates and discontinue use of non-pneumatic nebulizers. The alert addresses incorrect tidal volume delivery when non-pneumatic nebulizers are used due to faulty leak estimation, and corrects alarm delay delays and flow sensor anomalies caused by aerosol accumulation. Healthcare providers and home health service providers (PSAD) must act immediately.
