A judge has ruled that brain-dead teen Jahi McMath will remain on a ventilator for at least another week. Meanwhile, a bitter war of words rages between the hospital and McMath's family.

After a judge extended a court order keeping her 13-year-old brain-dead daughter on a ventilator in an Oakland hospital, Nailah Winkfield remained defiant to medical experts, insisting that Jahi McMath is alive.

“My daughter is breathing,” Winkfield told reporters Monday after an Alameda County judge issued the temporary restraining order through Jan. 7. “She moves. When I go in there and touch her, she moves her whole body, her legs, her shoulders. How can you possibly say my child is dead if she responds to my voice?”

The family has been trying to find a facility that will take Jahi in while at the same time fighting in court to keep her on a ventilator at Children's Hospital Oakland, where she was declared brain dead on Dec. 12 -- three days after a complex tonsillectomy surgery.

Sam Singer, a public relations consultant retained by the hospital, said the family must find an outside physician willing to insert breathing and feeding tubes, a way to transport Jahi and a nursing care facility that is willing to accept "a deceased person."

"The hospital continues to give its deepest condolences to the family, and we hope they can come to terms with the death of Jahi McMath," Singer said outside the hospital.

The case has tugged at the hearts of people across the country who are sympathetic to the family's pleas that Jahi be given a chance to live. Experts in law and medical ethics, meanwhile, say she is legally dead with no chance for a change in her condition.

Jahi suffered heavy bleeding, cardiac arrest and "whole brain death" — defined as an irreversible cessation of all functions of the entire brain, including the brainstem — on Dec. 12. Two hospital physicians and three outside doctors requested by the family deemed her brain-dead, court records show, and the county coroner was notified. But the family protested the hospital's intention to remove Jahi from a ventilator.

Tests by an independent physician named by the court also determined that the girl is legally dead. They showed no blood flow to the brain, an inability to breathe on her own and no sign of electrical activity.

There is broad medical and legal consensus that whole brain death constitutes one of two legal definitions of death. A Harvard Medical School panel first put forth the standard in 1968, and in 1981 a presidential council proposed that a uniform statute be adopted nationwide. It was published as the "Uniform Determination of Death Act."

Another presidential council reaffirmed in 2008 that "whole brain death" is legal death.

However, in her petition for an emergency stay in the state court of appeal, Winkfield contends that the act violates her freedom of religion and privacy under the California Constitution.

The temporary restraining order initially issued by Alameda County Judge Evelio Grillo on Dec. 20 had been set to expire at 5 p.m. Monday. The family attorney, who sought the original restraining order and the extension, is appealing Grillo's determination that Jahi is brain-dead and filed a separate case in federal court.

Singer said hospital attorneys plan to fight all three.

The McMath family lawyer has said three facilities have expressed a willingness to accept Jahi, but Singer said "this hospital has had no substantive conversations with any of them."

Two West Coast facilities withdrew their offers, family members said, but they maintained Monday that a New York facility is willing to accept the girl.

Omari Sealey, an uncle of Jahi, said the family has a contract with the facility and has arranged for medical transport. But Singer countered that the hospital has questions about the documents that purportedly confirm the New York facility's commitment.
