Bobbi Kristina was without oxygen for five to eight minutes, according to published reports.
And, despite reports that she is showing some signs of improvement that the swelling in her brain has subsided and her eyes fluttered, the situation is very dire.
Doctor Armand Dorian is an emergency room physician, he told INSIDE EDITION, "The impression that we're getting, currently, is that there's been significantly brain injury. It may not be total brain death but she will never be the same person she was. She may never be able to walk out of the hospital if she does survive."
The stricken Bobbi Kristina is caught in a family feud involving her husband Nick Gordon vs. Whitney Houston's family.

When police got there, they found Nick Gordon attempting CPR. They also found Maxwell Byron Lomas who, two weeks ago, was arrested for possession of marijuana and Xanax.
Family friend Kim Burrell said the family was worried, but there was little anyone could do to control Bobbi Kristina.
"I am concerned about her environment and the company she was keeping. Since the passing of Whitney -because Whitney was hard on Bobbi Kristina. I mean, like, 'No I said now! Get in here now! Do this now!' I mean that kind of mom. But we've not wanted to cross certain lines and we don't want to offend her, we don't want to push her further away," Burrell told INSIDE EDITION.
