About this trial
The goal of this clinical trial is to evaluate whether different inspiratory-expiratory (I:E) ratios in the pursed-lip breathing (PLB) technique can improve respiratory outcomes in patients with stable Chronic Obstructive Pulmonary Disease (COPD) aged 40 years and older. The primary purpose is to determine whether a specific breathing intervention can improve respiratory function.
The main questions it aims to answer are:
Does PLB with different I:E ratios (1:3, 1:4, and 1:5) reduce respiratory rate in COPD patients? Does PLB with different I:E ratios improve oxygen saturation and reduce dyspnea severity?
Researchers will compare PLB with I:E ratios of 1:3, 1:4, and 1:5 and a control group receiving standard care to see if different ratios produce different effects on respiratory rate, oxygen saturation, and dyspnea levels.
Participants will:
Perform pursed-lip breathing using assigned I:E ratios (1:3, 1:4, or 1:5) for 10 minutes Be assigned to either an intervention group or a control group (standard care) Have their respiratory rate measured before and after the intervention Have their oxygen saturation measured using a pulse oximeter Report their dyspnea level using the Modified Borg Scale before and after the intervention
