FEV1/FVC reduced- but Pulmonologist insist it is not COPD .
I am a 35 Year old male , who has never smoked .
Has a regular work out routine.
I had an appointment with my pulmonogist as a follow up to a a CT scan I had taken as part of my immigration physical.
The CT scan was to rule out any active TB infection - and the CT scan ruled so - indicating my lungs were allright.
I just wanted to get this confirmed with my pulmo , hence the appt.
Since this was my first time , I was asked to do spirometry and PFT .
I am worried abt the numbers I see on my test results ...
FEF25-75% 53% -
all of these post bronchi dialtor admin.
My TLC , RV , RV/TLC , DLCO are all normal.
I am worried that the reduced FEV1/FVC may indicate COPD.
But the Dr was quite confident that it was not .
In fact he even did not diagnose me for Asthma.
He ruled out Emphysema and also chronic bronchitis .
His interpretation was this :
No Obstructive pulmonary impairment. Mid flows slightly decreased. Flow volume loops indicate a variable intra thoracic airways obstruction. Lung volumes by nitrogen washout show no abnormality . The DLCO is normal.
I have no symptoms for Chronic Bronchitis - that is productive cough for at least 3 months in the past two years . I do get some cold infections a few times in a year . Mucous for a week and dry cough for 3 weeks after and then I am fine.
He said I wouldnt need any further follow ups . Question : 1) Can COPD really be ruled out ? 2) Do I need a follow up on the variable intra thoracic airways obstruction part ?
