Getting certified (at least for the association I use) requires that you are able to demonstrate rescuing an unconscious diver at the appropriate depth (after identifying their blackout).

Well done helping that person. Rescuing a free diving blackout has the benefit (for the rescuer) of an unconscious victim.
