متن کاملImpaired lung compliance and DL,CO but no restrictive ventilatory defect in sarcoidosis.
Sarcoidosis is a systemic granulomatous disease with predominant manifestation in the lungs, often presenting as interstitial lung disease. Pulmonary function abnormalities in sarcoidosis include restriction of lung volumes, reduction in diffusing capacity of the lung for carbon monoxide (D(L,CO)), reduced static lung compliance (C(L,s)) and airway obstruction. The aim of the present study was ...
متن کاملObstructive? Restrictive? Or a ventilatory impairment?
Since 1991, the guidelines for interpretation of lung function tests endorsed by the American Thoracic Society (ATS) have recommended that the presence of airflow obstruction be determined by a reduction in the ratio of FEV1 to FVC (or vital capacity), but that the severity of the obstructive impairment be indicated by the reduction in FEV1 itself, expressed as a percent of its predicted value ...
متن کاملDefining obstructive ventilatory defect in 2015
INTRODUCTION There is no clear consensus as to what constitutes an obstructive ventilatory defect (OVD): Is it FEV1/FVC<lower limit of normal (LLN) or<0.70 (respectively, physiological and operational definitions)? AIM To determine, according to the two definitions, the percentage of subjects having an OVD among them explored in a lung function exploration laboratory. POPULATION AND METHODS...
متن کاملObstructive sleep apnea complicating negative-pressure ventilatory support in patients with chronic paralytic/restrictive ventilatory dysfunction.
The purpose of this study was to determine the incidence and severity of obstructive events and oxyhemoglobin desaturation (dSaO2) in 37 patients with paralytic/restrictive ventilatory insufficiency during use of nocturnal ventilatory assistance provided by means of negative-pressure body ventilators (BVs). Thirteen of the 37 patients had mean oxyhemoglobin saturation (SaO2) less than 95 percen...
