Pneumothorax is a medical emergency that requires immediate treatment due to its direct impact on respiratory function. Pneumothorax is easily recognized due to its sudden onset with symptoms of severe chest pain, dry cough, and difficulty breathing.

Pneumothorax is a common condition that occurs when air enters the pleural cavity, leading to lung collapse due to increased pleural pressure. Patients with pneumothorax should have a thoracentesis performed as an initial treatment.
