It is that simple. Out of gas, and the deco is over. You can try to improve the situation by having some emergency O2 on the surface for use on the surface. If you have surface support, well then even better. Maybe they can bring you some extra gas. Either way skip breathing doesn't seem to be the answer especially if you are pushing the PO2 limits for that paricular dive. This just doesn't seem smart. Any body used the DAN "REMO" system? It appear to be an O2 rebreather for surface emergency use. They say you get about 6X extension out of your emergency O2.
