BREATHING EASY: simple lip trick may soothe COPD patients after scary lung test

This study tests whether a nurse-guided breathing exercise called Pursed Lip Breathing can help people with COPD feel less anxious and have better vital signs (like heart rate and oxygen levels) right after a bronchoscopy. Sixty-four adults with COPD will be randomly assigned to either receive the breathing exercise or standard care. The goal is to see if this simple technique can ease recovery and reduce stress.
