COPD [Chronic Obstructive Lung Disease] is one of several chronic diseases that are becoming increasingly problematic worldwide nowadays. Low- and middle-income countries already have much of the burden of COPD. Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines have identified the goals of treatment for patients with COPD, these include the patients’ goals of improved breathing pattern[exercise tolerance] and emotional function (health-related quality of life), clinical goals such as prevention of disease progression and minimization of symptoms . Nurses care for patients with COPD across the spectrum of care, from outpatient and home care to emergency department, critical care and hospice settings. Many reviews shown the commonest techniques to reduce dyspnea that are being applied to patients with Chronic Obstructive Lung Disease (COPD) subjected to a pulmonary rehabilitation program (PRP) are breathing retraining strategies. The Pursed lip breathing (PLB) and diaphragmatic breathing (DB) are breathing retraining strategies employed by COPD patients in order to relieve and control dyspnea. Through breathing retraining we can improve their breathing pattern along with routine medical care. Patient & family teaching is an important nursing intervention to enhance self-management in patients with COPD.
