Well true to Ian...he has not had any issues since being in the hosptial. No issues means they can't see what is going on and no way to change vent settings. We did try a new medicine for anxiety which Ian did well on. In addition he had a trial yesterday and today of being off the vent for 30 minutes each, he did great both times. Having this knowledge along with the anxiety medicine will allow showers to go smoother, we hope. So now we wait for discharge orders, finish packing him up, and head home ....to treasure yesterday, dream of tomorrow, live for today.
