1,000 ways to die

[Hoomi]

You all know where this has to go, don't you?

MYTHBUSTERS!

My guess is, they'll try and explode a pig.

It's funny, though; my first thoughts when finding this topic on page 1 this morning was related to the question someone had of people diving to 300' on scuba.

Just this week, my coworker and I were watching Freediver videos on Youtube. William Trubridge broke the unassisted Freediving record by reaching 88M (288') with no fins, weights, or any other dive equipment besides eye goggles and an exposure suit. Guillaume Nery reached 109M (app. 355') in the Constant Weight Freediving category, using a monofin.

Nery reaching the 109M marker on his guideline is on the video, so my guess was that there were scuba divers posted along the way for both recording the feat, and safety. It'd be rather wild, wouldn't it, if someone without any kind of breathing apparatus could dive deeper than someone with scuba gear...

(but he didn't explode on surfacing...)

First, being a scuba instructor the max depth when I taught was 130 fsw. Second: after that you used a mix gas or a different set of dive tables, Ie the wheel (gee is that still around) ah then came computers thats when everyone got bent Why you ask??? Because No one paid attention to them. How do I know all of these Issues.. I have been working with HyperBARIC (NOT HYPERBOLIC) chambers for the last 25 years.
I have seen many diver who planned there dive but did NOT dive there plan!!! Or just didn't pay attention to where they were. Or taking too many pictures, or entering a wreck with out any training, or exercised before/after they dove. Drank way too much, partying on vacation. I would tell my students the 2 D's don't mix Drinking& Diving oh and on land just add the R.
In a hyperbaric chamber if someone is "bent" dcs, decompression sickness depending on there symptoms Stage I-II-III their placed inside and compressed either to a U.S. Navy 6 table or a U.S. Navy 5 for type II or III. Milder type "skin bends" can be treated at 60 fsw.The signs and symptoms of dcs is from skin bends to dead. a lot inbetween

the first thing a diver will do IS deny...denial is what will get scuba divers in trouble all the time "ah I'm not bent my shoulder hurt me yesterday I picked up my dive bag funny, ect some lame excuse. Not realizing what there profiles have been for the last 4 days, doing 2 to 3 tank dives
Presently I am working at the largest Multiplace chamber in the Northeast. I am the Clinical Coordinator. We treat patients with non-healing wounds, softe tissue necrosis, with many other aliments. These folks get better with about 30 treatments Breathing 100% at 45 fsw
NO NO!!!! once the chamber is pressure even to 2fsw the door can not be open. The guage must read ZERO. The door of a multiplace weighs 3000 lbs (so try opening that) and a monoplace chamber is several hundred. Every scuba diver better know his/her limits, keep inside them. If you do you will be safe. Stay away from your Maximum allowable bottom times. Remember you time to "crap out" and also remember you can't decompress in water with out enough air.. your screwed Good luck tabhbo50

Do you know what size your lungs become on a free dive..lets say the have a capacity of 20 liters on the surface, at 165fsw (there are 6 atmospheres in 165fsw) so divide that into 20 is..3 so your lungs go from the size of empty average size watermelon to a walnut. those folks do what is know "shallow water blackout" they use up all there O2. they blew off too much of there CO2 so there brain doesn't get the message to breath. Oh and those scuba divers are on Mix gasses..to go so deep. and they do have to decompress at some point. they a lot of redundant systems Ie.. a LOT LOT OF GAS TO SPARE.

When have you met a human with 20 liter lungs? Even Bob Croft was only about 15 pints.

 

[tabhbo50]

do you dive.. and you know nothing about a decompression chamber.. well then maybe you better not be diving at all

I suspect that it's the facts that are changed, not just details!

If this woman was in fact diving to 300' (quite possible on mix) and had to make a rapid ascent to the surface, I suspect she would have been fatally bent within minutes of surfacing, and that's assuming she didn't embolize or drown somewhere along the way.

i agree with this guy....
not to back track,or restate the obvious, or get too gruesome but didnt the Rouse's free ascend from like 230', that caused foamy blood according to the book, but I stongly doubt 300' or more could cause an explosion, we bring fish up from much deeper, they dont explode, i can believe the amount of embolism could look like an explosion in her chest cavity, i dont see her entire body popping like a baloon

 

[tabhbo50]

You say Hyperbaric chamber "sounds extravgant" what do you mean??

 

[tabhbo50]

Oh god that was just an example..the average person has a "vital capacity" of 6.. it was just a way of showing the math..

 

[meierdierck]

I think I see where you are going, but I am having trouble following your post....
130' -ok, mixed gas/dif tables/computers people dont pay attention- ok, plan your dive/dive your plan/dont drink and dive- ok, what is the "r"?, stages + Tx for dcs-ok,
chamber doors, personal limits, and "time to crap out"?

dude, not be rude, but you lost me, kinda all over the place

 

[tabhbo50]

you dont have to treat dcs at a 165 fsw all the time if the symptoms disappear there.. why go that deep... besides its the 100% of oxygen that gets the nitrogen out..the pressure gets out the bubbles.. so the pressure gradient and the o2 is what makes it work.. then there are times one would need to go to 165 feet..those people are on deaths door anyway.. trust me I have seen it.. My chambers max depth is 250 feet.. I have been at 165fsw in mine.. testing my fire suppression system.. Monoplace is 3 ata thats it..again 66fsw I have only been working with chambers for the last 25 years
