Subcutaneous Emphysema (Medical Definition) | Quick Explainer Video

Subcutaneous emphysema is a medical condition characterized by the presence of air or gas beneath the skin. This can occur as a result of trauma or injury to the chest or neck, causing air to leak from the lungs or other airways into the surrounding tissues. Subcutaneous emphysema can also be a sign of a more serious underlying condition, such as a punctured lung or infection. Symptoms may include swelling, a crackling sensation when the skin is touched, and difficulty breathing. Treatment typically involves addressing the underlying cause of the air leak and providing supportive care to alleviate symptoms.
