Discharge delayed

The plan was to discharge David today after 3.  Prior to discharging David they took him on a walk up the hall.  He was short of breath, fell into the bed and his oxygen level was very low.  They immediately put him on oxygen and the levels returned to normal.  His doctor wants him to stay and be evaluated by a pulmonologist and perhaps go home with oxygen.  The ultrasound of his kidneys and bladder that showed no damage that would cause blood in the urine.  There is currently no blood in the urine, that was Monday.  His bladder is emptying fine.  His lungs show a little bit of "effusion?" But not much.  The pulmonologist will look at all of the labs, etc. tomorrow.  His heart beat has normalized after the medication prescribed two weeks ago.  His swallow test indicates that he is swallowing fine, with no aspiration.  The only reason that makes sense for the dizziness and fainting is the medication interaction and that has been changed.
The reason he went to see Dr. Clemo was he is so tired/exhausted and thought it was due to sleep interruption from getting up to urinate so many times at night.  Since then he has become progressively more tired, then not feeling right, then dizzy.  About a month ago he had trouble walking a block without stopping to rest.  Last Sunday in the park, he walked about 15 steps and then had to stop and rest.  He would wheeze when he stopped.  This is what happened today walking up the hall at the hospital and the nurses reacted quickly with oxygen.  Right now he is sitting up in a reclines with oxygen and dozing off.
David really, really wanted to come home today.  I wanted to take him home but Dr. Yusufi ( a good friend of David's good friend Zee) told me that it was risky and may result in me bringing him back here, so we decided to extend his stay until he is evaluated to be safe to return home.  I will bring my MacBook with some DVD movies tomorrow because Saturday TV is terrible.  We may be able to watch some of the ABC shows on the iPad today.
I feel much better today after a good night's sleep.  Now I need to write email messages to the students whose class starts on Monday at 9 so that they have the right book and Internet access...or maybe just wait and have them do it in class on Monday. Either will work.
Than is coming over later as well as Zee.
