Raymond Hitchens deadly disease progressing.

So on Monday 08/12 Dad was admitted to the hospital and the next day transferred back to Christiana Hospital. His O2 levels have dropped significantly, and his throat has almost completely swollen shut. He cannot eat or drink without almost choking to death. Yesterday they inserted a breathing tube and life-support, today scans have shown increase in brain fluid and on the stem. Without the machine he cannot breathe and if they cannot find a solution to stop or slow the progression of his SEVERE autoimmune disease he will die…. His heart is now being affected so there is talk of a pace maker… dad is sedated so he’s not in any pain. I just don’t understand how 3 months ago he was okay and now he’s just getting worse and worse. Now he can’t walk at all. No function in the right arm and barely in the right leg. He can barely talk eat or drink… he did 4.5 weeks in rehabilitation and over a month in hospitals…. Please pray for my dad, for a miracle l, or just to slow down with some quality of life he’s still so young. At this point I’m terrified….
