PURPOSE A new spirometric reference equation was recently developed from the first national chronic obstructive pulmonary disease (COPD) survey in Korea. However, Morris' equation has been preferred for evaluating spirometric values instead. The objective of this study was to evaluate changes in severity staging in Korean COPD patients by adopting the newly developed Korean equation. MATERIAL...
The purpose of this study was to determine fixed cut-off points for forced expiratory volume in one second (FEV(1))/FEV(6) and FEV(6) as an alternative for FEV(1)/forced vital capacity (FVC) and FVC in the detection of obstructive and restrictive spirometric patterns, respectively. For the study, a total of 11,676 spirometric examinations, which took place on Caucasian subjects aged between 20-...
BACKGROUND We have previously suggested that it is possible to predict oxygen desaturation during flight in children with cystic fibrosis and chronic lung disease by non-invasive measurement of oxygen saturation following inhalation of 15% oxygen--the pre-flight hypoxic challenge. This study reports on the results of measurements over 5 years. METHODS The study comprised a pre-flight hypoxic ...

BACKGROUND Carrying out quality spirometric maneuvers in preschool children in both the diagnosis and follow-up of respiratory diseases continues to be very scarce. This is due to several reasons, including a lack of consensus on quality criteria and the acceptability of the test. The purpose of this study is therefore to obtain reference norms from a population of healthy preschool children fr...
Cerebral language lateralization can be assessed in several ways. In healthy subjects, functional MRI (fMRI) during performance of a language task has evolved to be the most frequently applied method. Functional transcranial Doppler (fTCD) may provide a valid alternative, but has been used rarely. Both techniques have their own strengths and weaknesses and as a result may be applied in differen...
Introduction: Renal failure affects the mechanical and the ventilatory function of the lungs. A few studies have evaluated the ventilatory and pulmonary function in dialysis patients. The present study aimed to compare Pulmonary Function Test (PFT) results in patients undergoing Hemodialysis (HD) and Peritoneal Dialysis (PD). Materials and Methods: We conducted a cross-sectional study on 50 pa...
