Yes.

The patient's total lung capacity is near normal. Some patients with COPD actually will have increased total lung capacity due to loss of lung substance and expansion of the chest cavity. However, the amount of air the patient can exhale in one second (the FEV1) is markedly decreased and the total amount of air the patient can forcefully exhale (the Vital Capacity) is also decreased. At the same time, the residual volume is increased. These results are characteristic of COPD and indicate air trapping (see below).

Pulmonary function tests (values shown as % of expected value): 

FEV1                   61%
Vital Capacity         73%
FEV1/VC              0.61  (normally >0.72)
Residual volume       175%
Total lung capacity   105%
Diffusion Cap. CO      13%

Pulmonary function tests in COPD (emphysema):

Note that the residual amount of air that can be exhaled in one second (FEV1) is decreased, the forced Vital Capacity is decreased, and the amount of air remaining in the lungs at the end of exhalation (the Residual Volume) is increased. All of these effects result from loss of elastic support of the airways, which allows the airways to collapse during exhalation, trapping air in the lungs.

In addition to evidence of obstructive disease, the diffusing capacity of CO is markedly decreased. The transfer of CO is affected both by the amount of surface area available for transfer and the quality of the air-blood barrier. Decreased diffusing capacity could indicate loss of lung tissue with reduced surface area, pulmonary fibrosis with thickening of the tissue barrier between blood and air, or a mixture of both.

Right ventricular hypertrophy by ultrasound is consistent with longstanding pulmonary hypertension and cor pulmonale.
