Pursed lip breathing to improve oxygen saturation in patients with Chronic Obstructive Pulmonary Disease
Main Article Content
Abstract
Chronic Obstructive Pulmonary Disease (COPD) is one of the leading causes of death globally and is associated with persistent respiratory symptoms and airflow limitation. One of the effective nursing interventions for addressing ineffective breathing patterns is the Pursed Lip Breathing (PLB) technique. This case study presents the nursing care process of five patients with COPD who presented to the Emergency Department with ineffective breathing patterns and low oxygen saturation levels (<90%). The PLB technique was applied as an evidence-based intervention aimed at improving oxygen saturation. Results showed a consistent increase in oxygen saturation post-intervention (average 95”“96%) and a decrease in respiratory rate. This case illustrates the importance of PLB as a simple, non-pharmacological, and effective intervention to manage dyspnoea and hypoxemia in COPD patients in acute care settings.
