Overview
Prognosis
Air in subcutaneous tissue does not usually pose a lethal threat;[1] small amounts of air are reabsorbed by the body.[2] Once the pneumothorax or pneumomediastinum that causes the subcutaneous emphysema is resolved, with or without medical intervention, the subcutaneous emphysema will usually clear.[3] However, spontaneous subcutaneous emphysema can, in rare cases, progress to a life-threatening condition,[4] and subcutaneous emphysema due to mechanical ventilation may induce ventilatory failure.[5]
