Relationship between arterial blood gas values, pulmonary function tests and treadmill exercise testing parameters in patients with COPD

Objective:  There have been controversial reports regarding the relationship between exercise tolerance and resting pulmonary function in patients with COPD. The aim of this study was to examine the relationship between resting pulmonary function tests (rPFT) and cardiopulmonary exercise testing par...

Description
Summary:Objective:  There have been controversial reports regarding the relationship between exercise tolerance and resting pulmonary function in patients with COPD. The aim of this study was to examine the relationship between resting pulmonary function tests (rPFT) and cardiopulmonary exercise testing parameters (CETP) and their value in estimating exercise tolerance of patients. Methodology:  In total, 45 patients with COPD (nine females, 36 males; mean age 61.2 ± 11.2) and 21 healthy subjects (four females, 17 males; mean age 60.3 ± 9.7) as a control group were studied. COPD patients (group I) were divided into three subgroups according to their FEV1 (mild/group II: FEV1 60–79% of predicted; moderate/group III: FEV1 40–59%; severe/group IV: FEV1
