Clinical Utility of Additional Measurement of Total Lung Capacity in Diagnosing Obstructive Lung Disease in Subjects With Restrictive Pattern of Spirometry.
BACKGROUND Total lung capacity (TLC), forced expiratory flow between 25 and 75% (FEF25-75%), peak expiratory flow (PEF), or post-bronchodilator volume response is recommended to detect obstructive abnormalities in the lung. The present study was performed to evaluate the usefulness of these pulmonary function test (PFT) parameters to diagnose obstructive lung disease in subjects with a restrict...
متن کاملErrors in the measurement of total lung capacity in chronic obstructive lung disease.
The standard plethysmographic method of measuring total lung capacity (TLC) has been reported to result in spuriously high estimates in patients with severe airway obstruction. The helium-dilution method is known to underestimate TLC in the same patients. To determine the magnitude of these possible errors we measured TLC by four methods in 20 patients with varying degrees of chronic obstructiv...

background: chronic obstructive pulmonary diseases (copd) are planned to rank fifth in burden of disease and third with respect to mortality by 2020. carrying out research regarding different aspects of copd is mentioned as important health priorities by academic institutions and governments. the burden of lung disease (bold) initiative was designed a decade ago to develop robust models that ca...
متن کاملSpirometry in chronic obstructive lung disease (COPD).
Introduction T common criterion recommended for diagnosis of chronic obstructive lung disease (COPD) is demonstration of “progressive irreversible airway obstruction” on spirometry. The Global Initiative for Chronic Obstructive Pulmonary Disease (GOLD) has recommended spirometry as the gold standard for diagnosis of COPD. However, spirometry is not widely available and spirometric test results ...
