ICU update

Just so everyone knows, my dad is improving. They have moved him from the ICU to the 4th floor of EIRMC. They still don't know what is wrong with him, but his oxygen requirement has gone down. He is now able to have a nasal canula with 5 liters of oxygen and can maintain his oxygen at 90%. They are pumping him full of anti-biotics and just hoping for some test results to come back with some answers.
Thanks for everyones prayers!
