Pneumothorax is caused by a rupture of the pleura, allowing air to enter the pleural space. Patients often display symptoms such as coughing, chest pain, chest tightness, and shortness of breath. A lung radiograph can confirm the presence of a pneumothorax. Whether a patient with pneumothorax can recover on their own depends on the size of the pneumothorax. If it is a large pneumothorax, especially a communicative or tension pneumothorax, self-recovery is not possible, and treatment generally involves pleural puncture or pleural drainage tube placement. However, if the amount of air in the pneumothorax is small and the patient does not exhibit severe symptoms, then it is possible for the condition to resolve itself with bed rest.
