Effects of Buteyko Breathing Versus Incentive Spirometry on Oxygen Saturation, Dyspnoea, Exercise Tolerance, and Sputum Clearance in Patients With Smog Induced Pneumonia

The current study will be a single-blind, parallel-group randomized controlled trial involving 62 patients diagnosed with smog-induced pneumonia. The study will compare the effects of Buteyko Breathing Technique (BBT) with Incentive Spirometry (IS) on respiratory outcomes. Participants will be randomly assigned to two groups using a concealed allocation method. The experimental group will receive Buteyko Breathing Technique along with standard medical care, while the control group will receive Incentive Spirometry along with standard medical care. Both interventions will be performed twice daily for approximately 20-30 minutes per session for seven days or until hospital discharge. Primary outcomes will include oxygen saturation (SpO₂), dyspnoea severity, exercise tolerance, sputum clearance, and respiratory symptom burden. Assessments will be conducted at baseline (Day 0), mid-intervention (Day 3), post-intervention (Week 2), and follow-up (Week 4). The study will be conducted at the pulmonary wards of Combined Military Hospital (CMH) and The Indus Hospital, Lahore. The hypothesis is that Buteyko Breathing Technique may produce greater improvements in oxygen saturation, dyspnoea reduction, exercise tolerance, and sputum clearance compared with Incentive Spirometry in patients with smog-induced pneumonia.
