good info!---
ty for posting it.

it's been a long time since i have had a PFT i forgot what all it involved.
it doesn't say= is this done in a regular room or is this where they put you in a glass box?
(this will be a 1st for me knowing not to drink coffee before it :) )

brenda= in my other post you mentioned you had to do this until 3 tests matched?
from what i remember it was exhausting to do---how the heck can you do it more than once & have the numbers "match"?

i had it done 3 years ago & my supplemental 02 needs have changed in that time; do they let you breath supplemental 02 if needed?

here's one for ya=
the guy at dr said i'd do a "plethysmograph"---i googled it & it said it was a test used for sexual offenders!!!
EEK!
but it turns out thats just the name of the "in chamber" machine; i think for now on brenda's "Telephone Booth" will be the term i use LOL

Jarca I THINK what Bren means by 3 tests, is they make you inhale/exhale 3 times to see if the graph thingy on screen matches up close enough..if one is different then maybe you had a little pause inbetween or whatever n you have to do it again, till 3 almost match...then I had some ventolin and 15 min break before the final test....this shows how much better your reading is with a inhaler....

That's just what I experience so maybe totally different for you...

Having this test tomorrow....3rd time in 3 yrs, hoping I am still Moderate and not moved up to Severe, don't think I will be but who knows.

gwapo= that does make more sense :)

it has been almost 3 years since i have done one & all i remember is the guy pushing me to keep blowing some candles on the screen out until i thought i would pass out.

joanneb=yearly/annually seems like a decent interval between testing to know what is happening.
you'll need to tell me all about it after you have yours :)
please know that my prayers are with you that you haven't progressed
(((HUGS)))

yes, thanks for sharing this! I really hate PFT's...they're like trying to run a marathon! I know they're necessary but I hate them any way!

Hi, Yes Gwapo is right, That is what I meant, that the graphs on her computer need to match up as close as possible for three times. I am in the "phone booth" and she says "blow, blow, keep on . blow " well that is hell for a person that has no air in the first place !! But it is necessary to determine where you are.

Just get in there, relax and when she says take a deep breath and blow, then do it as hard and fast as you can. I have not heard of them not accepting a test because things do not match up. Here in Temple Texas, they give you 5 tries, then she chooses the one test that has the closes 3 graphs.

Jarca, if you can visualize a growth chart for a business, you remember how the graph goes up as the profit goes up, well this is like that, as you blow the computer registers the pressure and puts it in graph form on the computer.

You have received good advice, so go to it my friend, and hope all these new tests and numbers show a remarkable inprovement.
