What Is Subcutaneous Emphysema?
2. Scuba Diving
Subcutaneous emphysema is a condition that some scuba divers are known to suffer from. It occurs because when the diver dives deep, the water above them causes the pressure to increase. This pressure causes the air in the body to become compressed. When the diver surfaces, the air in the lungs expands as the pressure begins to fall again.
If the diver does not exhale enough during this time then the lungs can become too full and rupture. Air escaping from the lungs can then result in subcutaneous emphysema, and it usually occurs in the neck area under these circumstances.
