Overview
Pneumothorax occurs when air collects in the pleural space between the lung and chest wall, causing partial or complete collapse of the lung. It can be spontaneous (occurring without injury) or secondary (caused by underlying lung disease).
Common Symptoms
- Sudden chest pain (sharp, often on one side)
- Sudden onset breathlessness
- Reduced breath sounds on examination
- Tachycardia
When to Consult a Pulmonologist
Seek prompt medical attention if you develop sudden chest pain and breathlessness, particularly if young and tall, or if you have underlying lung disease.
How We Diagnose It
Chest X-ray is the primary diagnostic tool. CT chest may be needed in complex cases. Oxygen saturation is monitored.
Treatment Approach
Treatment depends on size, cause and clinical severity. Small pneumothoraces may be observed. Larger ones may require aspiration or intercostal chest drain insertion. Recurrent cases may need specialist referral.
