High-flow nasal cannula versus noninvasive ventilation after extubation in people with systolic heart failure

A Prospective Randomized Controlled Trial Comparing High-Flow Nasal Cannula Versus Noninvasive Ventilation on Reintubation and Post-Extubation Respiratory Failure in High-Risk Patients With Systolic Heart Failure

NA · Yale University · NCT06671015

This pilot will test whether high-flow nasal cannula or noninvasive ventilation after extubation better prevents reintubation in adults with systolic heart failure who were on a ventilator.

What this trial studies

This is an open-label, randomized 1:1 pilot trial at Yale New Haven Hospital enrolling adults with systolic heart failure (ejection fraction ≤40%) who have been mechanically ventilated for more than 24 hours and are ready for planned extubation. Participants are randomized to extubation supported by either high-flow nasal cannula (HFNC) or noninvasive ventilation (NIV) using the Airvo 3 device. The primary outcomes are rates of reintubation and post-extubation respiratory failure, with reintubation decisions made by the attending physician. Results will inform the design and power calculations for a larger randomized controlled trial.

Who should consider this trial

Good fit: Adults (≥18) with systolic left ventricular dysfunction (ejection fraction ≤40%) who have been mechanically ventilated for more than 24 hours and are ready for planned extubation in the CICU or MICU are ideal candidates.

Not a fit: Patients with active COPD exacerbation or chronic hypercapnia, pre-existing NIV prescriptions, tracheostomies, do-not-resuscitate orders, agitation or inability to cooperate, prisoners, or those who self-extubate are excluded and unlikely to benefit from the study interventions.

Why it matters

Potential benefit: If successful, this approach could reduce reintubation rates and respiratory complications after extubation in people with systolic heart failure.

How similar studies have performed: Prior ICU trials comparing HFNC and NIV in mixed patient groups have shown mixed but often encouraging results, but randomized data specifically in high-risk systolic heart failure patients are limited.
