Clinical Causes: Spontaneous rupture of a small lung blister (bleb) or weak spot on the lung surface. Severe coughing, strenuous physical activity, or sudden movements that may cause lung rupture. Underlying lung diseases, such as emphysema or chronic obstructive pulmonary disease (COPD). Genetic predisposition leading to fragile lung tissue. None, in many cases, the exact cause remains unknown.

Key Symptoms: Sudden chest pain that may be sharp or stabbing. Shortness of breath or difficulty breathing. Rapid heartbeat (tachycardia). Dizziness or lightheadedness. Swelling or tightness in the chest. Cyanosis (a bluish tint to lips or fingertips) in severe cases. Feeling anxious or a sense of impending doom.

Diagnosis Path: Physical examination revealing decreased or absent breath sounds on the affected side. Chest X-ray to visualize air in the pleural space and lung collapse. Ultrasound imaging in some cases to detect free air or fluid around the lungs. In emergency situations, immediate thoracic ultrasound or portable chest imaging might be used to confirm the diagnosis before definitive treatment.

Treatment Protocols: Emergency needle decompression: Inserting a large-bore needle into the chest to quickly release trapped air. Chest tube placement (tube thoracostomy): A more definitive procedure to continuously evacuate air and allow lung re-expansion. Hospitalization for close monitoring and supportive care. Addressing underlying lung disease or risk factors to prevent recurrence. In some cases, surgery might be needed to repair the lung or prevent future episodes, particularly if recurrent pneumothorax occurs.
