Yes mate. From 23m in a quarry. She decided the only way was up which to be fair is not ideal. Stopped her ascent, got her on a buddy bottle and she made it. Happy days. Also was saved myself. Was diving a submarine, 2 sets, I was leader and decided to go to the the bottom. We infiltrated, did what we did and went for the surface. Got tangled in a net which unfortunately had the wire in the mesh which got tangled up on my pillar valve. Luckily my colleague was cool enough, as was I, to sort it out. We were at 53 m so bit of a problem. Ended up with 25 bar at the surface which is pretty close
