Your BC should never be used as a lifting device. Swim up and vent as required to control your ascent.
Like Padripo said, never do this. Deflate your BC upon ascent, the reason you do this is to let the expanding air out, if you don't do this you will ascend to the surface to fast and get the bends, bad thing. If you add air, it will make you more prone to ascending to quickly.
