Another step in the right direction! Breathing tube was removed around 9:30 AM and he took his first breaths with only 3L of Oxygen and his saturation levels are constant around 98-100% and his heart rate is staying in the 80's. They reduced some of his anti-rejection medications to help with the 2.2 creatinine levels in is kidneys.
He is able to talk sparingly as his throat is very sore, but it was fantastic to hear his voice! He said he feels like he is laboring a bit to breath deeply and test out the new lungs, so they put an oxygen mask back on (very normal as he's now inspiring on his own). Keeping communication to a minimum to let him focus on his breathing, but the nurses have become accustomed to his mannerisms to accommodate his needs. Got word from the medical staff, barring any set backs, that they will attempt to get him to sit up in a chair today, so he's excited about that news.
