hi guys,
This is what my dad's report says after the PFT test.
Obstrcution with possible restriction
No significant Brochondil
WARNING FEF2575POST = 23% Predicted

Here are some other values:

FVC Pre %pred = 43%
FVC POST %pred = 45% %chg=6

FEV1 Pre %pred = 36
FEV1 POST %pred = 35 %chng = -2

PEF Pre%pred = 23
PEF POST %pred = 25 %chng = 7

FEF2575 Pre %pred = 27
FEF2575 POST %pred = 23 %chng = -15


I know that if the FEF2575 % change is more than 10% it is responsive to medication. But here it says -15%. What does this negative value mean? Please Please explain.


AND BEFORE YOU START EXPLAINING IT, PLEASE MENTION WHAT IS HIS HEALTH STATUS HERE? IS HE AT RISK? WHAT IS THE RISK?

PLEASE PLEASE REPLY...

Thanks,
Rakesh
