hi there - my father is 76 years old and was in great health. he was admitted to the ICU 16 days ago with pneumonia and a staph infection in his lungs. he suffered organ failure - heart, lungs and kidneys. his heart is now stable. he is intubated but has minimal ventilation support and is on dialysis. he has been off sedation for 8 days. he has not opened his eyes nor does he respond to verbal commands. he only responds to pain stimuli and touch. his CT scan showed no concerns. they are doing an MRI and an EEG today. i am so worried that he wont wake up. any advice would be so helpful.
