7 posts in this topic

This may sound crazy but I'm trying to figure out how to understand all the test's the dr's are giving my husband. (ANd I'm starting from scratch) (knowing nothing medical!!!) I found somewhere how to read PFT results on this site and I have Birdmans results My question is what is normal? So I'll no what to compare.

Thanks for any help

Birdman's Wife,

Here's a link to PFT Interpretation. It's got information on what's normal and not normal spread throughout the page. For example:

TLC < 80% > 70% of predicted mild restriction

TLC < 70% > 60% of predicted moderate restriction

TLC < 60% of predicted severe restriction

 

I hope this is what you are looking for. Let's us know if you need additional information and we'll see if we can find it for you.

 

Big Hugs

I'm new to pfts. There's a lot of numbers. I know TLC and DCLO are important. What other numbers are worth noting?

Peanut,

I'm so glad you asked this question because it finally got me to do some research since I never really knew the answer and have never had a pulmonary doctor be specific other than the DLCO. So I scanned through the Scleroderma Care and Research Journal Spring 2006 and found an answer on page 19. Here is a portion of Table 2.

 

Table 2. Predictive Factors for Pulmonary Fibrosis (PF) and

Pulmonary Arterial Hypertension (PAH) in SSc

 

Pulmonary function tests...............PAH...........PAH+PF............PF

FVC <60........................................- .................++................ +++

FVC/DLCO <1.4..............................-................... -................. +++

FVC/DLCO >1.6........................... +++.............+++..................-

DLCO <60%.................................+++..............+++.................+

 

(I apologize for the sloppy formatting but the table didn't copy over too well so I tried to duplicate it.)

 

I think I'll print this article out and really read it at my next 5 hour infusion. I might get a lot of nap time in. :)

Wow Janey That's great stuff. I'm a little cross eyed from all the medical terms but it totally helps. Thanks!

Some of the terms my rheumatologist used were.

FVC forced vital capacity. FEV1/FVC Forced Expiratory Value. FEF25-75 Mine was 0.52 Predicted was 2.71 Mine was quite low. Indicating airway obstruction.

MVV Is used to indicate central airway disease. The FRC _RF_and TLC Pleth ones are for Overinflation of lung volumes. If those numbers or percentages are higher than Predicted.

DLCO is the Oxygen from air to bloodstream. A reduced Diffusion(DLCO) Indicateds a severe loss of alveolar capillary surface. I will find out more on my PFT's when I see my rheumatologist. I thought my numbers were good but most were terrible.

Raw is suppose to be less than 2.00 Mine was well over 4.

Sgaw was suppose to be greater than 0.21 mine was 0.06 and my over inflation lung volumes were from RV pleth was suppose to be 1.45 and mine was 3.21 (221%) I know that isn't good. If I find out anything more I will let you know. Hopefully, this wasn't too confusing. Sheryl


Strength and Warmth,

Sheryl
