Most divers are never taught proper deco technique in traditional diving courses. The key to responsible decompression dives is planning and. There are a few different kinds of decompression stops/ pauses in ascent, which a scuba diver needs to make to allow for the expelling of inert. In a broad definition, we can say that a decompression dive is one where the diver must make one or more mandatory stops prior to reaching the surface. The purpose of the stops are to allow the reduction of inert gases in the body.

Decompression diving second part of the table help us calculate the effects of nitrogen still in our body before our next dive.

Exit Strategy: Scuba Diving Decompression Explained

The surface internal and previous dive gave us a new NDL for our decompression diving dive at the depth we planned. In our training we learn that these table assumed a maximum assent rate.

We generally see 30 feet per minute as the rate we wish to stay below. This slow controlled assent allows the body to continue to expel nitrogen from our tissue at a rate that balances its growth in size due to less pressure. It also helps prevents expanding air to decompression diving caught in the ears and chest causing ruptures.

This is the same as a deco stop as far as its effect on the body, allows more time to let the body expel gasses. For the recreational diver, the question of should we avoid a decompression dive, the answer is a simple yes. The explanation might not be as you expect however.

Most divers will find that the amount of air remaining will require them decompression diving surface before reaching the NDL. Depending on the surface internal, the same may be true for the second dive.

Decompression diving with me here. It's trained on the gridlocked parking lot, and simultaneously reduces all the cars to half their normal size.

Now decompression diving cars fit into two lanes, some of them slip between barrier posts and even the Navigator can ease by the bus bench. The parking lot clears much quicker with less damage. As cars leave, the shrinking ray can be gradually turned off.

Recompression also slows down the rush of nitrogen from your tissues to your bloodstream because it reduces the pressure difference, or gradient, between tissues, blood and lungs. Decompression diving allows more of the nitrogen, both dissolved and in small bubbles, to flow freely and escape instead of ganging up into bigger bubbles.

With a smaller pressure gradient, nitrogen molecules are, in a sense, less eager to leave your tissues, so the analogy might be to a decompression diving show that holds at least some of the fans in their seats for a while.

When recompression squeezes bubbles small enough, their surface tension overwhelms their internal pressure and they continue to shrink on their own.

Nitrogen molecules are forced out of these bubbles. Now, as individuals, they can move more freely decompression diving the cells of your tissues and make their way down your bloodstream.

In the same way, that shrinking ray is going to make some decompression diving those cars uncomfortably crowded, and some passengers will get out and walk. And that, basically, is how recompression treatment untangles the traffic jam of bubbles that we call decompression sickness.

It's no different from clearing a jam-packed parking lot — if only the Dodgers had that Amazing Shrinking Ray.

Opening The "Oxygen Window" But it's not quite the whole story.

Decompression (diving) - Wikipedia

There's one problem with simply recompressing the bent diver. For every breath he exhales in a recompression chamber, he inhales another. If he's inhaling air, 79 percent of it is nitrogen under pressure, which he certainly doesn't need more of.

Assuming the pressure in the chamber is less than the pressure in his tissues, he will still off-gas nitrogen, but it decompression diving take longer.
