Joan Rivers' condition after she went into cardiac arrest on Thursday has not improved much at all. She's still listed as being in "serious" condition, hooked up to a life support machine to keep her breathing.

The doctors have apparently started the process of waking her up from her medically induced coma, but they are uncertain how serious the damage may be to her brain from the period of time she wasn't breathing.

Her family will soon have to make the tough decision of whether or not to keep her on life support, if her body cannot breathe on its own.
