Do submariners get decompression sickness?

Raised internal pressure in a distressed submarine rapidly increases the risk of decompression sickness (DCS) following submarine escape. The hypothesis that breathing a hyperoxic gas during escape may reduce the risk of DCS was tested using goats.

Do submarine crews get the bends?

The crew inside the submarine are not subject to the outside sea pressure. Therfore they do not get nitrogen build up in the blood stream. So they are not susceptible to the bends.

Do you feel pressure in submarine?

Even if the submarine dives to 300 meters (I’m picking something at random), you’ll feel mostly the same. It will be just like enjoying a cup of tea in a windowless room at sea level. This is because the interior of the vessel is kept at an approximate pressure of 1 atmosphere, which is what you feel at the surface.

Why do submarines have to surface slowly?

Each submarine is assigned an area of the ocean, either moving or stationary, depending on its tasking. If a sub finds itself outside that area because of navigational uncertainty, ocean current, or administrative error, they are required to surface immediately.

How do submariners avoid the bends?

Literally a hood with a plastic face mask attached to a life jacket, the Steinke Hood allowed the crew member to breath air trapped in the hood on their ascent following escape. Breathing in the trapped air reduced the chances of contracting the bends if the user breathed normally.

Why are there no windows in a submarine?

There is no reason to have a window because submarines are submerged almost all the time. Besides, there is nothing to see. Submarines operate in open ocean and stay away from any kind of ocean floor. Using external lights to allow people to look through a window would defeat the purpose of being stealthy.

Does air pressure change in a submarine?

Now, a submarine is basically a metal container filled with air, and there is just enough air in a submarine to exert the atmospheric pressure at sea level. If the submarine goes underwater, the amount of air within it does not change (unless there is a leak, of course), so the pressure within the sub remains the same.

Do your ears pop in a submarine?

No. The effect on air pressure of the compression of the hull at depth is minimal. There may be a pop when equalizing with the atmosphere prior to opening hatches on the surface. The ability to clear one’s ears (valsalva) is critical to serving on a submarine however.
