No compressions in the water - just rescue breathing. Even that may be outdated from a clinical perspective at this date due to the twin difficulties of keeping an open airway, and keeping the diver from aspirating vs. the minimal benefit such breathing probably has vs. faster exit from the water. I'm increasingly of the mind to plan to put a regulator in a distressed diver's mouth while swimming hard for the shore/boat, and occasionally pressing the purge valve.
I can see the value of using an immediate series of rescue breaths to attempt to get the body to spontaneously breathe on its own, but the more I read about in-water diving accidents, the less I have come to accept that a distressed diver can benefit from such breaths. I suspect most distressed divers have airways full of water (no way to clear), and/or air embolisms from rapid ascents (fluid/blood in lungs and no way to clear).
If you're so far from shore or boat that rescue breathing looks like a good choice, you're probably too far away to complete a successful resuce anyway.
