Detour from the O2 argument - Spearboard.com - The World's Largest Spearfishing Diving Boating Social Media Forum

I've been wondering about the oxygen issue for a while, and it seems like everyone that uses it use cylinders. I was curious if anyone had thought about buying one of the medical O2 concentrators that old people use in the home. The one we have at work will push 5 lpm between 90-95%. They're probably a little big for a small boat, but if you have a cabin or a bigger console, they wouldn't take up too much room, not sure about how much power they would draw, but you don't have to worry about running out. 5lpm is on the low end of the recommended range for a non-rebreather, but fine for a face mask. Anyways, just curious if anyone has thought about it. You can find them used less than $500, and there is one in the flyer from yesterday for $195.

Don't have the boat for it yet, just thinking

The advantage to a scuba cylinder/regulator setup is that you can also hang it for planned (or unplanned) deco stops and in-water recompression in the event that it's your only option.

Can't do that with the medical setup.

I doubt that would be a workable solution, check with DAN, they would know.

In order for O2 to help with DCS, it has to be in high concentrations, preferably 100%.
