The aim of this study was to investigate whether measurements of vital capacity (VC) are affected by the direction of the manoeuvre (inspiratory vs expiratory) and by the rate of expiratory flow. The study was performed on 25 individuals with chronic airway obstruction (CAO) and a forced expiratory volume in one second (FEV1) (expressed in standardized residuals (SR)) of -2.0+/-1.4 SD (CAO grou...
Background and Objective: Chronic obstructive pulmonary disease (COPD) is a worldwide health problem with increasing prevalence. It is often associated with negative health outcomes, including depression. Therefore, the aim of this study was to determine the prevalence of depression in patients with COPD. Materials and Methods: This cross-sectional study with a descriptive-analytic design was ...
Abreviations: COPD: Chronic Obstructive Pulmonary Disease; PEP: Positive Expiratory Pressure; CF: Cystic Fibrosis; Log G*: Mucus Impedance; MCI: Mucociliary Clearance Index; CCI: Cough Clearance Index; PDPV: Postural Drainage, Percussion, and Vibration; IPV: Intrapulmonary Percussive Ventilation; ACBT: Active Cycle Breathing Technique; HFCWC: High Frequency Chest Wall Compression; ELTGOL: Slow ...
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...
However the effects of endurance training on respiratory system is approved somedeal but, few and contradictory evidence exist concerning resistance training (RT), so the purpose of this research was therefore to study effects of eight weeks circuit RT (CRT) on pulmonary function of inactive women. Nineteen volunteer healthy inactive women were randomly divided into 2 groups: without tra...
The aim of this study was to evaluate the applicability of American Thoracic Society and European Respiratory Society criteria for spirometry in children. Maximal expiratory flow/volume (MEFV) measurements from 446 school-age children, experienced in performing MEFV manoeuvres, were studied and acceptability (start-of-test (backward extrapolated volume as a percentage of forced vital capacity (...
Periodically, the Joint American Thoracic Society/European Respiratory Society Working Group on Infant Lung Function Testing publishes results of workshops on new techniques for lung function testing in infants. One such half-day workshop on forced expiratory flow-volume curves from raised lung volumes in infants was held by the Infant Lung Function Joint Working Group of the ATS and ERS immedi...
BACKGROUND Airway clearance techniques include positive expiratory pressure, commonly used in our clinical practice, and a recently introduced temporary positive expiratory pressure device called UNIKO®. It is unclear which one provides the best benefit to patients. OBJECTIVES The aim of this observational 4-year study was to retrospectively compare the efficacy of and specific indications fo...
OBJECTIVES To study individual effects on pulmonary function of exposure to hard metal including cobalt. METHODS All of the workers in a hard metal company (583 men and 120 women) were examined for smoking, respiratory symptoms, ventilatory function, occupational history of exposure to hard metal, and present exposure to airborne cobalt. The ventilatory function indices (forced vital capacity...
