SCBA oxygen

I was wondering if the SCBA set up for divers would work as the same thing as other O2 setups... Also if anyone knows of an inexpensive source for O2 products, I would really like to know about it...
Thanx

No, that is O2 and nitrogen, I do believe, you need pure O2 my friend.

So really only medical botles or welding bottles are worth getting..... OK thanks for all the info.

SCUBA tanks would work to hold O2 and breathing through a SCUBA regulator would give you the pure O2.
But,
Who's going to fill the tank?
A SCUBA shop certainly wouldn't do it.
A welding supply wouldn't do it.
And a medical O2 supplier wouldn't do it.
Keep your SCUBA tanks filled with air and go diving. I have never been hit with a cluster while diving.

I was on a live aboard dive boat and one of the divers was a certified cave diver from central Florida. He brought a SCUBA setup that was filled with pure O2. He used it after deep dives or dives that went beyond the maximum time at depth. I borrowed it a couple of times when the beast paid a visit. Yes Bob G, I've been hit many times whyle on dive trips and a boat is a hellova place to try to take the beast for a walk. Dunno where he got the O2 fills, certainly not at a dive shop; technical diving (a mix of O2 and air with a higher O2 content) didn't exist then And it ain't cheap. Tank about $100.00, regulater $200.00 + and that's back in the late 80s. Welding O2 is a cheaper alternative but requires some adaptation. jonny is our resident expert on that.

You're right, a SCUBA outfit for clusters would be an expensive way to go.
And you're also right about getting hit on a boat. Would not a good place to be during an attack. No place to hide, no place to pace and screaming would be considered rude.

Do you guys use the little bubbler thingie that adds moisture into the O2 to keep from drying out, or is that just an unnecessary expense?

I dont see were $2.50 would be a unecerssary expense.
It's worth the cost.

I dont use O2 but I would like to get my hands on one of those little bubbler thingies.
So much to do, so little time.

You could get by for a short time without it, probably no effect. But breathing gas with 0.0% humidity for any length of time is going to dry out your throat and lungs. Worse than any extended airplane ride (which has 10% humidity or less).

I don't use a bubbler but floridian makes a good point. O2 has virtually no moisture content but a bubbler should be a simple thing to rig. My concept is a gallon water jug from the local stupidmarket, drink or spill off a cup or so and then drill 2 1/4 inch holes in the cap and insert the O2 tube from the tank all the way to the bottom of the jug. Insert the tube going to the mask in the other hole above the water line. You might need a sealant for the tubes at the water jug cap but most anything would do, ie, hot glue gun. silicone caulk, chewing gum, etc. jonny, any critiques?

Bobkip, your design sounds good. Your right that it is pretty simple. The idea is similar to a bong or hookah though this is a push design, not a pull). As Prense suggested, keep it clean. My sis is on a ventilator alot from her dystrophy (not oxygen - normal air, filtered and humidified), and she uses distilled water in her bubbler thingy. She also has a water trap between her and the bubbler to catch condensation, but I don't think that would be needed for the average Cluster O2 apparatus. Her humidifying chamber has a capacity of 20-30 ounces, and the fill line is about halfway (say 15 ounces water, 15 ounces headspace over it). An airstone from an aquarium shop would increase the diffusion of water vapor into the O2, but I don't think that is needed, and I don't know if those things might give off evil humors. Get food grade plastic tubing. Engineer to withstand 1500 p.s.i.

I agree Jonny, it's money well spent.
I used o2 w/out the "bubbler" for several months and it dried my nose out so bad I was getting nosebleeds.

Sure Kip, You got to much damn time on your hands....LMMFAO ....Go to the med joint and buy one....LOL
Like Flo said, you should use distilled water in it.
I just push the cup into the crushed ice thingy in the front of my fridge and then the cold water thingy, what the hell...its filtered....LOL Cool 20
Really kip, that sounds like a great idea....Why dont you give the folks a run down on how to create real "Cool 02".....You folks will love this, Kip is the McGuyver of CH.COM

My guess is so that bacteria growth is kept to a minimum...
Just guessing

As you breath the water will evaporate. As it evaporates the minerals, bacteria, rocks and Volkswagens in the water will be left behind and make the bubbler dirty and make an ideal place for the bacteria to grow. Distilled water has the gunk removed.

Hadn't thought of this but geez with all the crap in our water it's a wonder I haven't clogged the damned thing up by now.
thanks for the tip guys,
