FEV vs FVC

[Chaggie]

Did my pft's the other day and my number seem strange to me,
 my fev's seem low, 54-45-24 but fvc is 101, does anyone else
get these kinds of numbers?

Yeah I used to be like that. I would be maybe 30% fev1 and about 65% fvc! I guess my lungs could take in a load of air but weren't that strong in blowing it out in the first second...

My FVC is 71 currently and FEV1 is 49 so yes thats how I am too. FVC is overall lung function and FEV1 really shows how much obstruction is in the lungs

My FCV1 3 days ago was 85 ( been in the hospital 10 days at that
point) and I got out today hopefully they a bit higher didn't do
another pft.  I guess I didn't pay much attention to my FEV
but I think it is around 50%

FVC 75% and FEV 61% - I guess I don't have what your talking about becuase my numbers are much closer.

 

[Chaggie]

Thanks everyone, I've just never had fev's this low before and I
don't understand, my activity level is way up I am not culturing
anything or coughing anything significant and my lungs feel great.

 

[LouLou]

Are you wheezing? Maybe you need to be on Advair...

 

[Chaggie]

No wheezing, not on advair but i do albuterol and serevant.
 My doc gave a precautionary cipro regimine and go back in 2
weeks, in the mean time I guess I'll have to just play more hockey.

My last one was FEV1- 44% and FVC- 68% .

I think my FEV was around 64 last time and FVC was around 89. I remember I've always had a bit gap between the two. I think its normal. Maybe has something to do with "air trapping" (the air you can get into, but can't blow out of your lungs)?

As of my last test about a month ago. My FVC was around 108% and my FEV1 was around 96%. This was the best I have been in over 10 years. I accredit it to the HS that I started on 2 months ago. But my FVC has always been 10-20% higher then my FEV1

Obstructive lung disease is where airways are narrowed or blocked, which usually results in a lower FEV1 result and normal or near normal FVC. Restrictive lung disease is where the total volume of air is less due to a problem with expansion, so is a lower FVC and better FEV1. I think that most of the time, CF can have both obstructive and restrictive issues, but most CF people I know definitely have more of an issue with FEV1.

I'm a weird case as I've always been the other way around. My FVC used to always be about 10% lower than my FEV1 but now that my FEV1 has gone down, they're only about 5% apart <img src="i/expressions/face-icon-small-smile.gif" border="0"> My FEV1 is 94% and FVC 90%.
