|
Confirmation and quantification of pulmonary restriction |
|
Confirmation and quantification of pulmonary hyperinflation and air trapping, especially in patients with dyspnea disproportionate to the degree of obstruction by FEV1 |
|
Preoperative evaluation of volume reduction surgery |
|
Monitoring and surveillance of disease for clinical or research purposes |
|
Patients with any of the following functional patterns by spirometry: suggestive of restriction, PRISm, probable mixed |
|
Dyspnea or exercise intolerance |
|
FEV1 = forced expiratory volume in the first second. PRISm = preserved ratio impaired spirometry. |
