FIL is off the ventilator after 8 days!
FIL did well today. He held at the 45% FiO2 and breathed a lot on his own. They have been decreasing his sedation but kept him on meds for anxiety for now.
The nurse said once it's out he'll still be plenty groggy. She also said his muscle tone isn't great, so they will have a therapist come work with him. He will need to stay in the hospital for several days yet after the vent is removed, but she wasn't sure how soon he would get moved out of the ICU to a normal room.
All in all a good update.
Good news.
