Post-Extubation High-Flow Nasal Cannula Versus Non-Invasive Ventilation in Type II Respiratory Failure

Brief Summary

Acute hypercapnic respiratory failure is characterized by elevated arterial carbon dioxide levels and commonly occurs in patients with chronic respiratory diseases. Patients with type II respiratory failure who experience difficult weaning from invasive mechanical ventilation are at increased risk of post-extubation respiratory failure and reintubation. This randomized clinical trial compared high-flow nasal cannula (HFNC) with non-invasive ventilation (NIV) as respiratory support immediately after extubation in patients aged over 50 years with type II respiratory failure and difficult weaning. The primary objective was to compare reintubation rates at 72 hours and 7 days after extubation.
