Some good ideas I think.

I'm curious to know though why change in PO2 can't be used to indicate successful delivery of O2. I know sensors have a significant lag time, but if the controller injected a whack of O2, depth hasn't changed, and PO2 has actually decreased (rather than just staying the same), then surely after say 30 seconds, then there's a fault, and you could flash lights at the diver?
