FVC = 0.1524*Height(inches) - 0.0214*Age(years) - 4.6500 [Men]
FVC = 0.1247*Height(inches) - 0.0216*Age(years) - 3.5900 [Women]

FEV1 = 0.1052*Height(inches) - 0.0244*Age(years) - 2.1900 [Men]
FEV1 = 0.0869*Height(inches) - 0.0255*Age(years) - 1.5780 [Women]

here are equations i found at <a target=_blank class=ftalternatingbarlinklarge href="http://www.hopkinsmedicine.org/pftlab/predeqns.html

It looks like the raw fev1 volume is expected to drop .0255 liters per year for a female. Or very roughly .75 liters in 3 decades.

I did the same exact thing (plotting past 15 years) just a few months ago. My FEV1 hasn't gone down at all, however, my fev25-75% has gone down a fair amount.

I love this question. Sadly, I don't know the answer either. <img src="">

I remember when I was 10 years old and doing PFTs and I wanted to bring in my friends to do it so we could compare. I should have! If anyone has a very cool pulmonary lab, or a PFT machine in your house, start giving PFTs to your family and friends amd tell us the results. <img src="i/expressions/face-icon-small-tongue.gif" border="0">

Edit: Thank you for the info jdubbs.

Mine haven't budged much since my diagnosis-- even with lung damage. Weird!! My husband's are lower than mine (No CF).
