Breathing Under water

[bowman316]

You know what I want to try this summer,
I want to get a long hose, and tie one end to a float, so it will stay above the water. Then Put the other end in my mouth so I can breath under water.

I really think that would work.
Just something fun to try out sometime.

You should invest in one of those exterior scuba suits with the grates across the helmet that you used to see on Scooby-Doo episodes(my 3 year-old son is in a Scooby-Doo phase). That will complete that package for ghetto scuba diving.

Here is one example http://www.deep-sea.net/deep-sea/files/history/fig2a6.jpg

Re: Breathing Under water

I have scuba dove before, and nothing can compare to just breathing under water. Just that alone is worth it, much less what you get to see.

You almost feel high sometimes, just really relaxed. If you freak out you may die.

Yeah, its a lot of fun. The part about freain out and dieing is totally true though!

You may want to think about a splash guard for the end of the tube though. I hate getting a big gulp of water when i am expecting air

You gotta watch that Nitrogen narcosis- that will make you forget that you are underwater and causes all kinds of problems.

Do you dive in the Chesapeake? What kind of coral in there...any?

Re: Breathing Under water

I have never dove in the Chesapeake, but I hear a dive shop around here will do it in late summer/ early fall. But There is virtually no vis.
Yon can't see your toes when you are in ankle deep water.

I learned to dive in Australia on the great Barrier reef.
Also dove last year in St. Thomas.
Did my one and only night dive there.

It would basically be a big snorkel, but I wonder is the rules of decompression would still apply, since you are breathing air coming from the surface at normal pressure?

But I think that has more to do with the air getting compressed in your lungs after you breath it in.

Re: Breathing Under water

that co2 you just exhaled is coming right back into your lungs on the inhale, that's why you feel high.

Re: Breathing Under water

Actually it would be an epic fail. The water pressure just a few feet down would prevent you from inhaling. Thus diving regulators are used on dive equipment to equalize the water pressure with the air pressure. Snorkling works under water (well for a second or two) as the water pressure is pressing on the air in the tube as well as the pressure on your lungs.

Re: Breathing Under water

You are kidding, right? You can't breathe through a tube under water. You'd need a compressor and a regulator.

Re: Breathing Under water

I have never really tried it, But I did take a 2 ft hose, and trap air in it, and go 4 ft under, and i could breath that air out.

And about the CO2, It may be a good idea to breath out thru your nose.
but you could have to wear a mask that would allow that.

this has actually been invented and patented. I though i might have been the first to think of this.

Re: Breathing Under water

The hose idea isn't going to work.

If you don't want to mess with a tank and a regulator and will only be going in relatively shallow water, then;

Re: Breathing Under water

Yea, they said if the compressor stops, then it will get harder to breath, as the air will be less compressed.
I think when you are at 2 ATM's you need twice as much air, because it is compressed more. So when you are breathing in uncompressed air, You need to breath twice as much to get your normal breath.

But they say it gets easier to breath as you get shallower, with no compressor.

Re: Breathing Under water

Won't work....
Your lungs can't pull air down more than a foot or so.

But hey, give it a try and let us know how it works for you.
Just be ready to come up...
I'm a little surprised they didn't teach you that in your open water one class?


Diver Down....

Re: Breathing Under water

The told us the effects of diving and decompression and all, but never fully explained why it happened. They just said you breathe twice as much at 2 atms and 3 times as much at 3 atms, and so fourth.

But you don't have to "pull" the air down, it should already be in the hose, right?

or will the hose collapse due to pressure?

I just found an article that explains it,
You need compressed air to match the pressure pushing in on your chest as you go deeper. The non compressed air can not apply enough pressure to equal what is pushing in on you.

Re: Breathing Under water

Another "not gonna work". I tried it once in my pool and that
density*gravity* height = pressure stuff from fluids class is real.

Re: Breathing Under water

the reason a snorkel works is because it's short, the reason a long hose won't work is because on your exhale you're blowing all the air out and then sucking that same c02 back in, going deeper is only gonna speed it up, it's common sense, even if you try shallow or skip breathing it's gonna work up until the c02 levels in your bloodstream rise and your lungs start screaming for o2.

Re: Breathing Under water

It gets physically impossible for your diaphragm to pull air into you lungs the deeper you go and why you need a regulator and tanks to push air into your lungs as you descend to deeper depths. Ya just can't fight physics...

 

[blouderback]

Re: Breathing Under water

Yeah, I tried this in my pool a couple of years ago, and I couldn't suck in air even at just 3 feet under. Too much pressure.

Won't work. Just get a snorkle, mask, and fins.
