Interpritation of Spirometry,PFT;29 year old female

Interpretation of Lung Volumes; 29 year old female.I am a very active, typically healthy, active, 29 year old female. For as long as I can remember I have had troubles with breathing.

When I was younger I was diagnosed with asthma. To my recollection this diagnosis was based merely off of symptoms alone.

I have found myself short of breath walking up stairs, talking, even standing and doing dishes. I began to seek medical attention and through process of elimination, it appears that I may have a restrictive problem with my lungs.

I was going to have a amnitol challenge done with my spirometry, however, the tech. decided the challenge was no longer necessary after seeing my results from the spirometery. I also have values for diffusing capacity and resistance.

Here are the results:


Ref Pre %Ref

FVC Liters 4.50 3.75 83
FEV1 Liters 3.57 3.32 93
FEV1/FVC % 79 89
FEF25-75 L/sec 3.88 4.18 108
IsoFEF25-75 L/sec 3.88 4.18 108
PEF L/sec 7.25 7.26 100
FET100% Sec 2.93
FIF50% L/sec 3.95

Lung Volumes:

TLC Liters 6.35 **4.36 **69
VC Liters 4.50 3.75 83
FRC PL Liters 3.36 **1.89 **56
ERV Liters 1.49 **0.81 **54
RV Liters 2.05 **0.61 **30
RV/TLC % 29 **14

Diffusing Capacity:

DLCO mL/mmHg/min 27.7 24.1 87
DL Adj mL/mmHg/min 27.7 24.1 87
DLCO/VA mL/mmHg/min 4.62 5.69 123
VA Liters 4.24
IVC Liters 3.33


Raw cmH2O/L/sec 1.12 2.72 244
Gaw L/sec/cmH2O 0.807 0.367 46
Vtg (Raw) Liters 2.44
Raw f BPM 81

I am awaiting the next step, but I was told not to work out or exert myself until further notice. I really enjoy working out. I was told that it could be scar tissue, and if so there is no treatment or anything to make you more comfortable. Thank you in advance for any help!
