my friend was admitted to the hospital after drinking steadily for about 4 months. She was having seziures so they have put her in an induced coma. The dr now says there is some sort of infection that they do not know the source of and she is shutting down . What does this mean?....Her husband tells me they say she may not survive the next day or two if the cannot find the reason for the infection. What do you think they mean by shutting down
