really freaky checkup yesterday

[tara]

I have a problem with your FEV1 comparison. When you say you "blew out" 1.7 Liters, are you saying your FEV1 was 1.7 Liters? (FEV1 is the volume of air expelled during the first second of expiration during the PFT.) If so, here's my problem.

If my assumptions above are correct, based on yesterday's results your FEV1 was 1.7 Liters and the percentage FEV1 calculated was 48%. That translates to a predicted FEV1 of 3.54 Liters.

Based on your previous clinic visit results, your FEV1 was 1.8 Liters and the percentage FEV1 calculated was 70%. That translates to a predicted FEV1 of 2.57 Liters.

Do you see what I'm getting at? If I'm interpreting your values correctly, they changed your predicted FEV1, by A LOT! That doesn't happen from visit to visit, as your predicted FEV1 is based on your height and weight.

Don't get caught up on the percentages. They can be wrong. Just look at the liters. You lost a tenth of a liter between visits. No matter what the predicted is/was you did lose some function, but not a lot. You certainly didn't drop from 70% to 48%. More like 70% to 67%. (assuming 2.57 is the correct predicted liters???) That's up for debate as well. How tall are you? I'm 5'4" and my predicted is around 3 Liters. It depends what model they are using. I think Hankensen (sp?) would give you lower predicted values, but it's meant for children under the age of 18.

Hope this helps.

I agree with Tara and wanted to mention that my predicted changes once in awhile cause of them taking my height each time and they sometimes get a different height and then they plug that number into the computer. So, that messes up my predicted. Clearly, being 30 years old, I should be at a stable height, so they really ought to use the same value to keep results consistent, but sometimes they don't.

I wouldn't worry too much unless you FEEL sick. I know that's easier said than done though. Beleive me, I've gotten a lot of "kicks to the gut" when I think I'm doing well and my results are depressing. It doesn't always mean I'm worsening though... Sometimes we just have "off" days. Ya know? Good luck to you. <img src="i/expressions/heart.gif" border="0">

wow tara u know yur stuff-sorry bout the one hand /holding baby typing,
all i know is that doc said i blew out approx 1.7 liters and last time it was bout 1.8.
my height is 5'3 and i weigh 123....
oh.......wait.....last time i went i weighed 129. i lost 6 lbs since then bc of my exerc prog.
could that have something to do w this?

Hi Christian,

The six pounds shouldn't make a difference, at least not that much! Come to think of it, I'm not even sure weight has anything to do with it. It might just be height, sex and age.

Like I explained earlier there are different models of predicted FEV1's. I think 2.54 Liters might be your Hankensen predicted FEV1. My Hankensen is 2.74 Liters and I'm 5'4". I'm not sure if one inch, 5'3", would lose two tenths volume but it sure makes a whole heck of a lot more sense than the wacky 3.54 Liters they had you at yesterday. I'd guess you'd have to be at least 5'8" and maybe male to have a predicted that high! LOL! That's why I asked how tall you were.

It just seems like maybe they had the wrong patient plugged in, or they had your height wrong. Just look at the liters and compare apples to apples. (1.7 vs 1.8) No matter what the predicted is, you lost one tenth of a liter between tests. At your age and any given day, that's not a whole lot. What you need to be careful about is the continual loss of a tenth of a liter. I hope your next FEV1 goes back up! Good luck.
