American Academy of Allergy, Asthma and Immunology, FVC: forced vital capacity; total volume of air a patient is able to exhale for the total duration of the test during maximal effort, DLCO: diffusing capacity of the lung for carbon monoxide, EIB: exercise-induced bronchoconstriction, LLN: lower limit of normal, defined as below the fifth percentile of spirometry data obtained from the Third National Health and Nutrition Examination Survey, TLC: total lung capacity; the volume of air in the lungs at maximal inflation, VC: vital capacity; the largest volume measured on complete exhalation after full inspiration, Asthma, left-to-right intracardiac shunts, polycythemia, pulmonary hemorrhage, Kyphoscoliosis, morbid obesity, neuromuscular weakness, pleural effusion, Asbestosis, berylliosis, hypersensitivity pneumonitis, idiopathic pulmonary fibrosis, Langerhans cell histiocytosis (histiocytosis X), lymphangitic spread of tumor, miliary tuberculosis, sarcoidosis, silicosis (late), Cystic fibrosis, emphysema, silicosis (early), Low DLCO with normal pulmonary function test results, Chronic pulmonary emboli, congestive heart failure, connective tissue disease with pulmonary involvement, dermatomyositis/polymyositis, inflammatory bowel disease, interstitial lung disease (early), primary pulmonary hypertension, rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis, Wegener granulomatosis (also called granulomatosis with polyangiitis).

A restrictive pattern can indicate restrictive lung disease, a mixed pattern (if a patient has an obstructive defect and a restrictive pattern), or pure obstructive lung disease with air trapping.
