How is the diver treated for the bends?

Answer 1

By represurising the diver to the presure that he was at then slowly normalising it. this is done in a decompresion chamber. If a decompression chamber is not used, the person will die immediatly. Do not pass go, do not collect 200$ The above is a nice basic answer. Decompression sickness results from bubbles occurring in the body after surfacing from a dive. The treatment is to recompress the diver in a recompression chamber (not a decompression chamber) to a certain pressure or depth. Different facilities use different treatment methods and therefore different depths as well as different treatment times. The pressure on the diver makes any bubbles in the body smaller and therefore easier to eliminate as well as relieving any pain the diver is experiencing from the bubbles. The diver is also given oxygen to breath since this will cause the excess inert gas in the diver (i.e. nitrogen if air was used to breath during the dive) to be eliminated faster (since nitrogen is no longer being breathed and therefore it has a pure driving force for elimination).

Answer 2

Under diving pressure, the body fluids become saturated with nitrogen. While pressure is maintained, the nitrogen stays harmlessly in suspension in the body fluids. As pressure is released, such as through ascent from the depth, the nitrogen is released from inside the body. During a proper ascent, nitrogen is released slowly and can be off-loaded from the body through the lungs. Too fast and the nitrogen is released inside the body as bubbles. It is the same effect you see when you suddenly release the pressure from a can of soda and the gas comes out of suspension. The nitrogen bubbles can migrate to all parts of the body causing severe joint pain or death.

When the body is re-pressurized, the nitrogen goes back into suspension--the bubbles disappear and further damage from them is stopped. The body can then be depressurized at a safe rate to prevent the bubbles from reoccuring. This does not necessarily reverse damage that was caused.

Answer 3

A diver with the bends must be taken to a chamber and slowly brought up to allow the nitrogen bubbles to be flushed out (by breathing). Most bends victims are taken to a replicated depth of 40 feet and they might stay on air for 20 minutes. Then brought to a depth of 30 feet and breathe for 25 minutes. And then to 20 feet for 15 minutes and ten feet for 18 minutes. This allows the nitrogen in the diver to be breathed out and discharge the bubbles from the dive they got the bends from.
