Neither measure is particularly accurate in characterizing severity, and neither measure is superior to the other.CLINICAL IMPLICATIONS: Spirometry must be used with caution when grading the severity of restrictive pulmonary disease.DISCLOSURE: The following authors have nothing to disclose: Sean Roark, ...

11,45,46 Organizing pneumonia in SLE is probably underdiagnosed due to lack of lung biopsies in symptomatic patients. The clinical symptoms include fever, cough, and dyspnea, and can mimic infection. Chest radiography shows nonspecific diffuse interstitial infiltrates with a restrictive lung defect on...

Prediction of forced expiratory volume in normal and restrictive respiratory functions using spirometry and self-organizing map. This work presents a prediction of forced expiratory volume in pulmonary function testing, using spirometry and neural networks. The pulmonary function dat... SC Manoharan,R Sw...
but DLCO is severely reduced79.The decrease in DLCO may result from a fall in alveolar volume (VA), representing the volume of CO distribution during the breath-holding maneuver mainly due to restrictive and/or obstructive defects and/or a fall in carbon monoxide transfer coefficient (KCO). Wh...

73.33% CHF patients had restrictive, 10.00% small airway obstruction and 16.67% combined restrictive and small airway obstruction feature. In addition, FVC and FEV1 (p<0.05) was positively and FEV1/FVC% (p<0.05) negatively correlated with EF% in chronic heart failure patients.Conclusion: Left ...

Conclusions COPD associated with exposure to silica-containing dusts appears to be associated with a more restrictive abnormality than COPD associated with cigarette smoking and coal dust, possibly because of a modifying effect of associated lung fibrosis....
