Tension pneumothorax, X-ray

Tension pneumothorax. X-ray of the chest of a patient with tension pneumothorax that has lead to soft-tissue emphysema. Tension pneumothorax is a progressive deterioration and worsening of a simple pneumothorax (collapsed lung). The right lung (dark area, right) has collapsed due to a build-up of air (solid grey) between the lung and chest wall. In emphysema, the lung tissues necessary to support the physical shape and function of the lung are destroyed. It is a progressive disease that primarily causes shortness of breath
