FW: [DYSPHAGIA] Blue dye test

[AWallace@echd.org (Ann Wallace)]

This is why I asked the question.  It seems to me that if blue dye can mix
with saliva and be aspirated in swallows of our own secretions (that's what
I was calling "osmosis"), then the blue dye test would be no good at all
because we would suction blue dye later from everyone.  This particular
patient had had quite a lot of blue dyed thin liquid - maybe half a cup -
spoonfuls followed by drinking from the cup followed by the straw - with no
blue dye suctioned at the time.  So basically, it seems to me that the blue
dye test is just a test of overt/frank aspiration at the time of the swallow
only.  Right?

it can be vallecular or pyriform residues, but can also be from residual
blue 
dye on the tongue, that mixes with saliva and is aspirated in swallows of
our 
own secretions--which "normals" do during sleep.  Depends on how much, how 
long from the study, after a blue dyed test meal, etc., etc.  That's when we

usually follow up with MBS or FEES.
