Pulmonary Function Test
HISTORY
Gerald Miller is a 66-year-old male.
With history of COPD, who presents for pulmonary function
testing. Tight is 68
inches. His weight is
252 lbs. The patient has
a history of smoking cigarettes for 36 years at 1.5 packs per day.
He quit smoking 15 years ago.
On the day of the study, he reports dispenser with walking
less than 100 yards, no cough, and no wheezing.
INTERPRETATION
Patient gave good effort and cooperation. The
PFT machine is calibrated daily. The results of this test meet the
ATSC standards for acceptability and repeatability. 4 Puffs of an
albuterol MDI were administered with an aerial chamber and were well
tolerated.
SPIROMETRY
There is obstruction by FEV 1\ FVC ratio which
is 32. The FBC is normal
at 3.47 L (90% predicted).
The FEV1 is severely reduced at 1.34 liter (45% predicted).
There is no improvement post bronchodilator.
LUNG VOLUMES
The total lung capacity is normal at 7.38 L.
111% predicted. There is
air trapping by lung volumes with a residual volume of 3.68 L (162%
predicted).
DIFFUSION CAPACITY
The DLCO is mildly reduced at 15.28 mL/min/mmHg
(61% predicted).
IMPRESSION
Severe obstructive airway disease with air
trapping by lung volumes and mildly reduced diffusion capacity.
There is no clinically significant post bronchial dilator
response.
2018 Complete
Pulmonary Function Test
There is severe reduction in FEV1 at 30% of
predicted and a mild reduction in FVC at 73% of predicted.
The FEV1 to FBC ratio severely reduced,
consistent with obstruction.
There is a 20% improvement in FEV1and a 90%
improvement In FVC post bronchodilator.
Post bronchodilator
spirometry continues to show severe air flow obstruction. Lung
volumes reveal severe hyperinflation of the RV.
Moderate hyperinflation of
the FRC. Consistent with air trapping, the DLC O is moderately
reduced at 17.2 at 56% predicted. And corrects to 70% for alveolar
volume.
IMPRESSION
PFT's are consistent with severe obstructive
lung disease.

Pulmonary Function Test
SPIROMETRY
The forced Vital capacity is moderately decreased at 3.02 liters.
Which is 69% predicted. The fav one is severely reduced at 1.59
liters. Which is 47%
predicted. There was no
significant change in spirometry values after bronchodilator
challenge.
LUNG VOLUMES
The total lung capacity is normal at 108% predicted.
The thoracic gas volume is increased at 172% predicted.
The residual volume is also increased at 177% predicted.
DIFFUSION CAPACITY
The DLC O and the DLA are moderately decreased at 57% and 63%
predicted, respectively.
IMPRESSION
Findings are indicative of severe obstructive
lung disease associated with air trapping and a moderate diffusion
impairment. There is
also a mild restrictive process which may be due to obesity.
