That's good to know. But if I understand your explanation of pressure dynamics correctly, it seems that the very safest thing would be to not only keep breathing, but to keep your breaths relatively shallow, so that your lungs never get to the point where they're dangerously near capacity. Does that make sense? Or is that equally dangerous for some reason? Is it perfectly safe to take deep breaths and letting your lungs fill to capacity as long as you exhale relatively quickly?

You don't need to breathe necessarily shallow. In fact, you want to breathe deeply, but not excessively so. As an example, right now, try taking a deep breath and pausing after the inhale. Then try to pull a bit more air in by inhaling even more deeply (without exhaling first). Then pause and see if you can get just a little more in if you try. You'll probably be a little surprised at how much extra air you can pack into your lungs if you inhale this way (your "inspired reserve volume"). If you just breathe normally deep breaths, this "spare" volume is ample safety as long as you don't actually *hold* your breath (i.e. by closing off your throat).
There's no need to be quick about inhaling or exhaling, as long as you keep your airway open. Try taking some slow deep breaths while keeping your airway open (i.e. without moving anything in your throat). If you breathe while maintaining an open airway, you can't build up pressure in your lungs to cause injury, even when breathing slowly and deeply, as you'd be trained to breathe on scuba.

Oh, and it is better to take deep breaths because when you breath shallow, you're only moving the air found in the anatomic dead-space - ie the air that isn't involved in gas exchange (the air in your trachea and bronchi). Depending on your weight, this dead space is usually around 150cc, so shallow breathing will eventually lead to poor oxygenation.
What do you mean exactly by "non-swimmer." If you really don't know how to swim, any deep water activities are dangerous. I used to be a lifeguard and almost every person I rescued was a non-swimmer who thought they would be safe in deep water on a float or wearing a jacket or hanging on to something.
In snuba, your only attachment to the surface is the air line. So what happens if you lose the mouthpiece?
Learn to swim, then you can start examining advanced options.

Hookah diving has been around for a long time. Google Weeki Wachee, I think this place has been open over 50 years. The main draw was the mermaid show where they breathed from hoses. I took my kids there a few years ago and you can dive the same spring and still see the mermaid show.
To say forget SNUBA and learn SCUBA is a narrow minded approach to an adjunct that will actually get you diving more.
My introduction to the underwater realm was via the Johnson Air Buoy. It was a small 2 cycle gas air compressor with two hoses, a mask that covered your nose, (to breath) with a snorkel valve. When you didn’t breath the air flowed out the valve. In 1969 Brownie introduced a floating compressor with hoses to a second stage. The Brownie Third Lung.
Imagine hunting lobster in Florida Bay, finding a nice hole full of bugs, then suiting up with tanks to efficiently collect all of the legal ones. OR. Fire up the brownie, pass down the regulator and collect your bugs. No tanks to take up room on the deck or running back to the dive shop for fills. The propaganda states you can dive to around 80 FSW but the limit I would set is 2 ATA, 60 feet. Plenty deep to see some nice reefs.
I have a hose assembly that allows me to use my BC with the power inflator from the brownie supply. Losing the weight of the tank makes multiple, shallow dives a lot easer.
If it’s easy, you’ll do more.
If you use ANY equipment that allows you to inhale air under water GET THE PROPER TRAINING. If you already have your c card, try it.

Very...Hey look at me...I'm a tourist...I think it's another resort way to get your money while making you look like a geek at the same time....Like Chris said...Go snorkeling...Please...
