Hi, Michellea, and welcome to the forum. I'm so sorry your mom is in such bad condition. Unfortunately, it seems that the hospital is keeping her alive with machines. Usually, when a person's organs start closing down--such as kidneys--and being unable to breathe independently, that's an indicator that the patient is close to death. Does your mom have a living will or has she made her wishes known as far as "extraordinary measures" used to keep her alive? Does she have a "do not resuscitate" order in her chart? I would think not, since she was intubated. How long has she been in a coma? Do you have siblings who might be of help to you?
I hope you will continue to post here and let everyone know how you are doing.
