Course Outline

Decompression illness (DCI) refers to both DCS and lung overexpansion injuries (arterial gas embolism or AGE). Although the term DCI is sometimes used interchangeably with DCS, you should be aware that there is a difference.

DCS refers to the condition caused by inert gas coming out of solution and forming bubbles within the body, and AGE is a pressure-related injury or problem. However, in an emergency, the first-aid provider will follow the same procedural response for either DCS or AGE.
