I just wanted to update everyone who was wondering what happened with the pulmonologist (see the previous post, please).  We ended up pushing the appointment back until August, so that the insurance people have a chance to work things out on their end.  BUT, one of the respiratory therapists that I have known basically forever informed Dad that my primary care physician can sign the paperwork for me to keep my second vent.  Yay!  That means all of this was definitely unnecessary stress.  Hopefully, everything is on its way to being straightened out.  Wish us luck and send good vibes!
