Best hospital for severe MAC infection with many complications

My brother is currently in the ICU and has now been on the ventilator for 4 weeks with a recent tracheostomy. He is 46 with a long medical history. He had no complications at birth, but began to have major problems at 6 months old. Pseudomonas that caused him to have to have plastic surgery to replace the roof his mouth. After that we stayed in and out of hospitals with lung infections, collapsed lungs, etc. He was diagnosed in elementary school with Sarcoidosis (which was changed to Still’s disease in 2005 after a splenectomy). He has had a hospital stay at least once every year of his life and many times we thought he may not make it, but he is a miracle and still here. Unfortunately this recent MAC Infection with a newly diagnosed CSID Disorder has him knocking on Heaven’s door (tears as I write this but we need help). He is 5’7” and might weight 100lbs. He is on the ventilator with a tracheostomy and every time they try to test him to come off the ventilator, his BP, HR and RR get extremely high. He has always had a lot of mucus production and now is unable to cough it up. The hospital he is in has been great, but I was wondering if we should try to move him to somewhere that specializes in MAC. Any help is appreciated and I am more than happy to answer any questions that will intern help get him better. Thanks so much.
