Thanks for your question on Healthcare Magic.
I can understand your concern.
By your history and description, she is mostly developing MODS (multiple organ damage syndrome).
Liver, lungs, kidneys etc are very vital organs of our body.
She is also not gaining consciousness, so her brain is also damaged.
So, in nutshell, her all vital organs are failing.
And this is not a good sign for prognosis.
Honestly speaking, chances of survival are very very less. Prognosis in her case is extremely poor.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your aunt. Thanks.
