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. While PLB is known to improve oxygenation and ventilation in pulmonary rehabilitation, its specific impact on the immediate recovery period after bronchoscopy is understudied. The study aims to determine if nurse-led PLB intervention significantly improves heart rate, blood pressure, oxygen saturation, and reduces anxiety compared to standard care.
Patients diagnosed with COPD
Patients undergoing elective bronchoscopy under sedation
Patients aged 18 - 80 years
Patients who are fully oriented, conscious, and able to communicate
Patients undergoing emergency bronchoscopy
Patients with hemodynamic instability prior to the procedure (systolic blood pressure <90 mmHg or >180 mmHg)
Patients with severe hearing or cognitive impairment
