FYI

I seem to recall that for a tuba player at a ff dynamic,
the flow rate is between 140 and 160 liters per minute.
This is about one breath every 2 seconds.  I don't recall
the flow rate for trumpet, but it's not uncommon for a
phrase to be 15-20 seconds long.  So going from about 30
breaths per minute on tuba to 3-4 breaths per minute on
trumpet is very significant.  Certainly this enormous
difference in breathing requirements will take on the
form of hypoventilation.
