Bobbi Kristina Brown has not shown much improvement since being rushed to the hospital on Saturday, January 31.

As we previously reported, the 21-year old only child of Whitney Houston and Bobby Brown was found in the bathtub of her Roswell, Georgia home face down in a bathtub.

TMZ reports that paramedics responded to a drowning call. When they arrived Bobbi's husband Nick Gordon was administering CPR. Gordon found his wife at around 10 a.m. She was rushed to North Fulton Hospital where she was placed in a medically induced coma. She has since been moved to a hospital in Atlanta.

Neurologist Eli Zimmerman of Massachusetts General Hospital told PEOPLE that the amount of time Bobbi's brain was without oxygen is critical.

The reason for putting Bobbi into an induced coma is to keep down the amount of energy the brain needs, according to Zimmerman.

"In some patients, the body temperature is dropped slightly to reduce energy requirements even more, though this is generally only done for 24 hours," he said. 

Various media outlets have cited anonymous hospital sources as saying it would be a miracle if Bobbi pulls through. If she does hospitalization will be extended for a long period of time combined with months of rehabilitation.

According to TMZ, doctors were encouraged Monday, February 2, by slight brain function improvement Bobbi showed when they administered a different stimuli, but warn the situation remains grim.

Her family has started making funeral arrangements.

Bobby Brown issued a statement asking for privacy.

“The report that Bobbi Kristina Brown has been taken to the hospital in Atlanta, Georgia, is accurate. No additional information will be forthcoming. Privacy is requested in this matter. Please allow for my family to deal with this matter and give my daughter the love and support she needs at this time.”
