HFNC vs. NIV in Acute COPD Exacerbations

NCT06495086 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 137

No results posted yet for this study

Summary

The investigators investigated the efficacy and safety of High Flow Nasal Cannula (HFNC) at different flow rates compared to non-invasive ventilation (NIV) in patients presenting to the emergency department (ED) with acute exacerbations of Chronic obstructive pulmonary disease (COPD) who did not respond adequately to bronchodilator therapy and continued to exhibit hypercapnic respiratory failure. Specifically, the investigators tested the hypothesis that HFNC would be more effective at reducing partial pressure of carbon dioxide (PaCO2) levels and hospital stay duration and would be associated with greater patient comfort than NIV.

Conditions

Interventions

DEVICE

NIV

The NIV group received bilevel-positive airway pressure. During NIV, the tidal volume was set to 6-8 mL/kg, positive expiratory end pressure (PEEP) to 3-5 cm H2O, and pressure support ventilation (PSV) to 8-12 cm H2O by a clinician with 8 years of experience. To reduce potential bias, the clinician was blinded to the null hypothesis.

DEVICE

HFNC-30

The HFNC-30 group received HFNC therapy at flow rates of 30 L/min. During HFNC, the humidifier was set to an open position, the heated air temperature was maintained at 37°C, and the FiO2 was adjusted to maintain an oxygen saturation (SpO2) measured via pulse oximetry of at least 92%.

DEVICE

HFNC-50

The HFNC-50 group received HFNC therapy at flow rates of 50 L/min. During HFNC, the humidifier was set to an open position, the heated air temperature was maintained at 37°C, and the FiO2 was adjusted to maintain an oxygen saturation (SpO2) measured via pulse oximetry of at least 92%.
