Humidified Noninvasive Ventilation versus High-Flow Therapy to Prevent Reintubation in Obese Patients: A Randomized Clinical Trial.

Background: The optimal strategy to prevent reintubation in obese patients remains uncertain. We aimed to determine whether noninvasive ventilation (NIV) with active humidification is superior to high-flow nasal cannula (HFNC) in preventing reintubation in obese patients at intermediate risk.

Methods: Randomized controlled trial in two intensive care units in Spain (June 2020‒June 2021).
