Introduction: Forced expiratory value in one score  (FEV1)/ Forced vital capacity (FVC) was used in classical literature for primary classifications of pulmonary disorders. American Thoracic Society/ European Respiratory Society guidelines recommended using FEV1/VC instead of FEV1/FVC.The aim of study was determination of the extent of superiority of FEV1/VC over the FEV1/FVC. Materials and Met...

Restrictive lung disease is a broad term encompassing a number of conditions in which lung volumes are reduced. Dyspnea is a common clinical manifestation of restrictive lung disease and frequently becomes a prominent and disabling symptom that undermines patients' ability to function and engage in activities of daily living (especially in those with more advanced restriction). Effective manage...

PURPOSE Lung size mismatch is a major cause of poor lung function and worse survival after lung transplantation (LTx). We compared predicted total lung capacity (pTLC) and TLC measured by chest computed tomography (TLC(CT)) in LTx candidates. MATERIALS AND METHODS We reviewed the medical records of patients on waiting lists for LTx. According to the results of pulmonary function tests, patien...

Introduction: Pulmonary involvement secondary to Systemic Sclerosis (SSc) is the major cause of morbidity and mortality in SSc patients. We designed this study to determine the correlation of important lung function parameters with lung High Resolution CT (HRCT) scan findings. Materials and Methods: Thirty–two consecutive diffuse SSc patients with pulmonary fibrosis were enrolled in this cross...

 ABSTRACT Background: The current practice to measure RV is either by BPG or helium dilution methods which may not be available in all clinics due to their cost. Methods: This paper outlines a method for both direct and indirect calculation of RV via PFT with acceptable sensitivity (81 %, 60% ), specificity (71 %, 94%) and validity (76%, 78%) for obstructive and restrictive lung disease respect...
