If you're scuba diving and you come up too fast?

Question

If you're scuba diving and you come up too fast you get air bubbles in your blood. I don't understand how this happens, and what does this cause that it kills you?
Thanks

Answer 1

DEAR,
AIR IS A GAS.
GASES BEHAVE AS FOLLOW :WHEN THEY ARE SUBJECTED TO PRESSURE THEY DECREASE IN SIZE WHEN THIS PRESSURE DECREASES THEY EXPAND.
IF YOU FILL A BALLOON WITH AIR , AT THE SURFACE IT HAS A CERTAIN VOLUME.
IF WE TAKE THIS BALLOON UNDERWATER ITS VOLUME DECREASES ACCORDING TO THE DEPTH.
ONE LITER BALLOON HAS A CERTAIN VOLUME AT SURFACE.
THE SAME BALLOON HAS HALF OF THE ORIGINAL VOLUME AT 10 METERS UNDERWATER.
THE SAME BALLOON HAS A THIRD OF THE ORIGINAL VOLUME AT 20 METERS UNDERWATER.
THE SAME BALLOON HAS A FOURTH OF THE ORIGINAL VOLUME AT 30 METERS UNDERWATER.
AND SO ON.
AIR IS COMPOSED OF OXYGEN 21% , NITROGEN 78% AND THE REST ARE SOME OTHER GASES.
OXYGEN IS BURNED BY OUR ACTIVITY.
THE PROBLEMS ARISE FROM NITROGEN.
NITROGEN IS ABSORBED BY ALL OUR TISSUES AND IS PRESENT ALSO IN THE BLOOD AS MICROSCOPIC BUBBLES.
THE BUBBLES IN OUR ARTERIES BEHAVE LIKE THE ABOVE MENTIONED BALLOON.
IF YOU COME UP TOO FAST , THE PRESSURE DECREASES AND THE BUBBLES DUE TO LOWER PRESSURE ON YOUR BODY INCREASE IN SIZE.
THE INCREASED IN SIZE BUBBLES , COULD BLOCK THE FLOW OF OXYGEN IN THE BLOOD TO THAT PART OF THE BODY.
IF THESE BUBBLES BLOCK THE FLOW OF OXYGEN IN THE BLOOD GOING TO THE BRAIN YOU DIE.

It's called "the bends" or decompression sickness. When you're very deep under water, the water pressure is very high and all of the nitrogen that's in your blood stream stays dissolved. When you rise suddenly to the surface, these makes the pressure on your body drop very quickly, and can cause the nitrogen to become "undissolved" and form bubbles. This is the same sort of thing that happens when you open a bottle of soda: you suddenly reduce the pressure on the liquid, and air bubbles are released. This can cause all sorts of problems, depending on where the bubbles accumulate in your body.

Answer 3

i actually wanna attempt it so badly, all my acquaintances who've lengthy gone scuba diving have cautioned it! that's on my to-do-list. Sky diving Scuba Diving Harry Potter topic Park Swimming with the Dolphins *a lot more beneficial*

Answer 4

If you're scuba diving and you come up too fast, you will get "the bends", because your blood cannot react to the change of density (depth, weight, etc.) of the water quick enough and it causes cramps and etc.

Answer 5

when you come up to fast you get decompression sickness. When you are down your lungs are like a balloon and get smaller. When you come up the excess nitrogen in your blood stream needs to escape and if you come up to fast they form bubbles. The bubbles in your blood is what kills you.

Answer 6

called "the ends". your blood bubbles (boils actually) because if you go really deep, the water is colder, and more dense. then you suddenly go to a warmer/ less dense area, and since your body is already used to being in the more dense place, your blood bubbles because your blood becomes less dense quikly and since the area around you is less dense, your blood begins to boil. it might not make sense, cuz im not explaining it well. but look at it this way- you know how on macaroni boxes it says "at higher elevation, cook.... minutes longer" that is because water boils at a lower temperature because the air around it is not dense, and the molecules are more spread out, when water boils it goes from a liquid to a gas, a gas being less dense, since the air is less dense, the water boils at a lower temperature to meet that density. for example- if you were able to place a bowl of water in a small chamber at sea level, and then some how removed enough air so that the air in the chamber has an extremely low density, you could get the water to boil, making bubbles. if you stick your finger in it though, it will be room temperature. hope this helps! and it kills you because your body cannot use gas blood, it has to use blood in the liquid form.

Answer 7

It's called "the bends." It's super-painful and you have to sit in a chamber for hours in order to reverse the effects.

Answer 8

That would be the rickets my friend.
