Looking into this some...
Quote:
Bradley, who has not examined Schiavo, did not attempt to say whether she is in a persistent vegetative state. But he said that for someone who is in this state, "there is no conscious perception of pain."
Quote:
In fact, Cranford said, Schiavo's inability to follow objects or people with her eyes was one of the main reasons he concluded that she is in a persistent vegetative state. He testified so in court.
"This diagnosis is so straightforward in her case," Cranford said.
Quote:
For that and other reasons, Maxfield concluded, and testified in court, that Schiavo is not in a persistent vegetative state.

"There's no treatment, no cure. Nothing known to science will help this woman."
-- Dr. James Barnhill, in 2000, testifying in Pinellas-Pasco Circuit Court.

What the courts say about Schiavo's brain
In a June 6 opinion that rouched on the medical evidence in the Schiavo case, the 2nd District Court of Appeal wrote" "Although the physicians were not in complete agreement concerning the extent of the daughter's brain damage, they all agreed that the brain scans showed extensive permanent damage to her brain. They only debate between the doctors was whether she had a small amount of isolated living tissue in her cerebral cortex or whether she had no living tissue in her cerebral cortex."

Q: What is a “vegetative state”?
A: A person in a vegetative state has experienced damage to the brain, and may be described as being unaware of surroundings, outside things or events, usually with periods of “eyes-open.” In this state, the person actually wakes and sleeps. Important body functions continue to work, including breathing, regular heart rate, and temperature and blood pressure control, and even sometimes, swallowing.
When awake, this person does not respond in a meaningful way to people or sounds, cannot feel pain, does not talk or walk.

Q: Do patients in persistent or permanent vegetative states experience pain or suffering?
A: No. The parts of the brain necessary for consciousness, that feel pain or suffering, are not working. Moving their arms or legs in response to unpleasant feelings or sounds are only reflexes.
Quote:
Q: What can we do once a patient has been diagnosed as being in a persistent vegetative state?
A: Three choices are possible: Provide aggressive medical treatment to keep the patient alive. Doctors will work to remove the mechanical ventilator, surgically implant a aracheostomy tube in the patient’s throat to protect him/her against choking and start medical nutrition (through a tube). If the patient survives, he or she will be transferred, when stable, to a long-term nursing care facility.
Try the above treatment plan for a specific time with the understanding that if no signs of recovery occurs, either some or all treatment will be stopped. Patients without any artificial treatment, including tubal feeding and fluids, usually die within 1-2 weeks.
Withdrawing artificial life-support immediately, including the breathing machine and medical nutrition (food) and fluids will allow the patient to die without discomfort. Since that part of the brain that no longer sends messages telling the brain to be aware of and experience pain, the patient will die without discomfort, usually within 2 weeks.

There was no agreement by the doctors about Terri's condition, but the majority concluded, as did the courts, that Terri was in a "persistent vegetative state," which, according to this, would mean she does not, indeed, feel pain.
