Some CPAP machines are difficult to regulate. I assume that the sleep setting would not be enough to sustain underwater pressure. If you survive using one underwater, please write and tell us about it.

I use a power snorkel from Brownie's Third Lung for changing my zinc and scraping barnacles. It's a 12 volt air pump with a corrugated medical hose and mouthpiece regulator. We paid about $600 for the rig.
I've also used an airpump from a CPAP machine, which has a similar medical corrugated hose and a nose mask. It's more refined, with pressure regulated from the pump machinery, but it's 110 volts. CPAP machines are used for positive pressure to prevent sleep apnia. They can be purchased on Ebay for reasonable amounts, like $250.
I'm not sure about getting a 50 to 100 ft hose. The power snorkel comes with 25' and the CPAP machine has about 15'. That should be enough for most applications.
