I find it interesting that before organ transplants people were only in comas and no one was looking to take their organs. Now transplants are big business and more people end up declared brain dead.
Karen Quinlan was diagnosed as pvs.
We have learned that pvs can be misdiagnosed in as many as 40% of cases.
She was not declared brain dead.
You are confusing coma and brain death as well as smearing the people who are working these cases.
