This morning, I awoke to Iain asking the Pulmonologists how quickly he could get off support.  Everyone had been encouraged how yesterday he had done 6 hours off the trache and walked 250 ft without ventilator support.  He asked to go back on the trache collar quickly which just administers a minimal amount of oxygen to speed up his rehab.  As he transitions to the trache collar the secretions which are kept down by the pressures the vent administers start to make him cough and these can be exhausting but he knows it and knows he has to get through it to be able to breath comfortably.  This time, his sats just kept dropping and his heart rate rose.  We initially thought it was  bit anxiety and tried to talk him through it. Eventually we all realized that something was going on.  Ultimately his left lung has collapsed.  The good news is that it may be due to a build up of secretions.  So they are trying to treat that.  So let us just hope that that is it.  Hopefully by tomorrow we will know more and as he had a bronch yesterday we should have those results (where they look for rejection and infection as a matter of course one month post-transplant).
