My specific question is this: we did a dive to 250' for about 15min. 3 of us were on OC & 1 was on a Rebreather. The Rebreather diver was diving 10/50 as diluent. At our 70' stop, I noticed bubbles coming up from below me & I knew the only person below me was the Rebreather diver, so I quickly started dropping back down & was frantically trying to get his attention to see what was going on. He kept signaling ok & was fumbling around with one of his offboard tanks & his CL. Once everything settled out, and I was convinced everything was ok, we finished our deco. On the boat, I asked what had happened and he said that he switched from his onboad diluent(10/50) to his offboard air(drysuit bottle). On this specific dive, does this make sense?

Hi I have being diving 60 to 70 meters, run times about 2 hours, 16/50 mix switch at 40m to off board air dill. I get out of water about 13 min earlier than not switching. At the 40m switch I do 3 long flushes so lots of bubbles. Hope this helps.
