Breathing technique may outperform spirometry for smog pneumonia recovery

This trial tests whether a specific breathing exercise, the Buteyko technique, can improve oxygen levels, reduce breathlessness, and enhance exercise ability in patients with pneumonia caused by smog. It compares this approach to incentive spirometry, a standard device that encourages deep breathing. The study involves 62 adults aged 25-40 with mild to moderate oxygen levels, who will practice their assigned exercise twice daily for a week. The goal is to see which method better supports recovery from smog-induced pneumonia.
