I can understand your concern. Atelectasis is partial collapse of part of lung. Most common cause for this is mucus collection in lungs. So treatment of atelectasis is 1. Broad spectrum antibiotic like levofloxacin or azithromycin once a day.2. Bucolic and expectorant Chat Doctor. 3. N acetyl cysteine NAC4. Chest physiotherapy and deep breathing exercises. So consult pulmonologist and discuss all these. Dont worry, your atelectasis will be improved with above treatment. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
