| Issue: | Analysis of the impact of nebulisers on performance of Trilogy Evo Platform ventilators revealed that using non-pneumatic nebulisers with Trilogy Evo Platform ventilators may result in a discrepancy between the set tidal volume and the tidal volume received by the patient. Non-pneumatic nebulisers change the airflow characteristics by adding liquid droplets, causing the ventilator's leak estimation calculation to be incorrect. This leads to under-delivery of therapy to the patient even though the graphic user interface does not display the change. This condition may occur with or without aerosol accumulation on the flow sensor. It is also not consistent with the requirements of ISO 80601-2-121. |
