The primary purpose is to determine whether a specific breathing intervention can improve respiratory function.\n\nThe main questions it aims to answer are:\n\nDoes 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?\n\nResearchers 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.\n\nParticipants will:\n\nPerform 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",[27],"Chronic Obstructive Pulmonary Disease (COPD)",[29,30,31,32],"Pursed-Lip Breathing I:E ratio in COPD","Oxygen saturation","dyspnea scale","respiratory rate","NOT_YET_RECRUITING","2026-04-30",{"date":36,"type":37},"2026-05-07","ACTUAL",{"date":39,"type":21},"2026-05-04",{"date":41,"type":21},"2026-08-14",{"name":43,"class":44},"Scholastica Fina Aryu Puspasari","OTHER",""]
