Hello,
This question was addressed in the UHMS guidelines for rescuing a non-responsive diver from depth. I have attached the paper here. I have also attached a report of a technical diver who made an unescorted unconscious buoyant emergency ascent (and survived) because it was impossibly dangerous for buddies to take him to the surface.
