In-water recompression
In-water Recompression
In-water recompression (pronunciation: in-waw-ter ree-kom-pres-shun) is a diving technique used to treat decompression sickness (DCS), also known as the bends.
Etymology
The term "in-water recompression" is derived from the words "in", "water", "re-" and "compression". "In" and "water" refer to the environment where the procedure takes place, while "re-" and "compression" refer to the process of increasing pressure on the body to alleviate symptoms of decompression sickness.
Definition
In-water recompression is a technique where a diver suffering from decompression sickness is treated underwater. This is done to take advantage of the increased pressure at depth, which can help to reduce the size of gas bubbles in the body that cause the symptoms of DCS.
Procedure
The procedure involves the diver descending to a depth where the pressure is sufficient to alleviate symptoms, typically between 9 and 18 meters. The diver then breathes oxygen at this depth for a period of time, which helps to eliminate the nitrogen bubbles causing the symptoms.
Risks and Controversies
In-water recompression is a controversial technique due to the risks involved. These include the potential for further injury due to the increased pressure, the risk of oxygen toxicity, and the difficulty of providing medical assistance to a diver underwater. Despite these risks, some divers and organizations advocate for its use in emergency situations where surface recompression is not available.
