U.S., Jan. 24 -- ClinicalTrials.gov registry received information related to the study (NCT07361978) titled 'The Effect of Pursed-Lip Breathing Exercise on Anxiety and Physiological Parameters Post-Bronchoscopy in Patients With COPD: A Randomized Controlled Trial' on Dec. 31, 2025.
Brief Summary: This randomized controlled trial investigates the effect of Pursed Lip Breathing (PLB) on anxiety levels and physiological parameters in patients with Chronic Obstructive Pulmonary Disease (COPD) following bronchoscopy.
