Predicting High-Flow Nasal Cannula Failure Using an Electrical Impedance Tomography-Derived Index: A Multicenter Study
Sponsor: Ruijin Hospital
Summary
High-Flow Nasal Cannula (HFNC) therapy is widely used to treat acute respiratory failure. However, predicting therapy failure remains challenging as conventional indices rely on intermittent measurements and cannot provide continuous, objective monitoring. Electrical Impedance Tomography (EIT) enables non-invasive, real-time assessment of regional lung ventilation. This study evaluated whether an EIT-derived Flow Index (FI) could predict HFNC therapy failure within 48 hours.
