A quick update on Mat.
First, I neglected to mention in my last post how things had deteriorated. During a procedure, one of his lungs was punctured and his chest filled with air. It took 3 chest tubes to relieve it. As a result of that trauma, he was put on a ventilator. So things were not very good at all.
The good news, however, was that today they took him off the ventilator and he's making progress towards coming home.
