New study tests gentler oxygen therapy for COPD patients after ventilator

This study looks at 150 adults with COPD who have just had a breathing tube removed. It compares two ways to help them breathe: a high-flow nasal cannula (a soft tube that delivers warm, moist oxygen) versus noninvasive ventilation (a mask that pushes air into the lungs). The goal is to see which method better prevents the need for another breathing tube within 72 hours.
