Stupid Human Tricks

David Letterman used to have a segment in his show called "Stupid Pet Tricks" this is my version; I was cleaning the filter and water bottle to my O2 machine.  I attached the bottle then the filter, unhooked my portable and put on the other cannula and wham I got a sinus full of water!  I fixed the problem soon as I recovered and thought all was okay.  Two days latr I was in the ER with aspiration pneumonia  and that night I n had to be given CPR and finally  a Trachiostomy.  So now I'm here in extended care.  Yes it was a Stupid Human Trick
