Comment Variable ratios to match breathing? (Score 1) 473
This sounds really interesting.
Though, if you have ever been scuba-diving, you will recall that your breathing is not constant throughout the venture.
In fact, there are times when you are breathing just normal, and there are times when you are really huffing and puffing.
How would this "oxygen-extraction bag" be able to pull out the particles of air out of the water at a VARIABLE rate, to match the variance in your breathing volume (not to mention the variance across individuals)?
Would the contraption be able to do this quickly?
I would hate to have to tell myself to stop breathing so heavy, because my air-extraction bag is deflating quicker than it's filling!
On the other hand, what if it is inflating too fast for you to breathe it in?
I suppose these are minor engineering considerations, but I didn't find mention of them in the article.
