What does extracorporeal elimination of undissolved gas from body fluids define?

The definition of extracorporeal elimination of undissolved gas from body fluids refers specifically to the process of decompression. This process is commonly associated with treating conditions caused by the formation of gas bubbles in the bloodstream or other body fluids, which may occur, for instance, in decompression sickness.

Decompression involves removing gas bubbles from the body fluids using various techniques that often require specialized equipment. This is essential in scenarios such as deep-sea diving, where divers can experience rapid pressure changes that lead to gas embolism.

Other options do not align with the specific meaning of extracorporeal elimination of undissolved gas. Performance typically refers to carrying out an activity or task but does not specifically address gas elimination. Renal dialysis is a process that removes waste and excess fluid from the blood due to kidney failure and does not focus on gas. Phototherapy involves treating conditions using light, which also does not relate to the elimination of gas from body fluids.
