I've done quite a bit of surveying on this sign. It is pretty much
divided 4 ways.1. Literally one out of four
people surveyed couldn't think of a sign off the top of their heads.
Then after thinking about it for a moment many of them did one of
the following versions:
2. Do a version of "lungs" using curved-5 hands.
3. Do the sign for "breathe."
4. Do the sign "BREATHE" but use "A" hands.
Place your hands about an inch out from your chest and then move
your hands downward, repeat.
ASTHMA (version)






Or sign:
BREATHE
