Spirometry is a time-honored, invaluable measurement for assessing lung function in individuals with chronic obstructive pulmonary disease (COPD) as well as for studying populations with COPD in epidemiologic studies.1,2 Indeed, the prognostic value of spirometry has been appreciated since the 1960s,3 and forced expiratory volume in the first second (FEV1) was more recently included in more com...

Aim. To develop a method for determining the lung inflation by indexes of forced expiratory flow­volume spirometry. Materials and methods. In 43 patients with mild persistent uncontrolled asthma in combination osmotic airway hyperresponsiveness, function were assessed spirometry using bronchodilation test bodyplethysmography. Results. From entire set parameters, regression analysis, two equatio...

The usefulness of peak expiratory flow monitoring is disputed because of the unreliability of written peak flow diaries. The aim of the present study was to examine the relationship of peak flow and forced expiratory volume in one second (FEV1) variation to other estimates of asthma severity in children, using an electronic home spirometer with automatic data storage. Over a 3-month period, 36 ...

BACKGROUND Asthma is common among young children. The assessment of respiratory resistance by the impulse oscillometry system (IOS), based on the superimposition of respiratory flow by short-time impulses, requires no patient active collaboration. AIM We evaluated the baseline repeatability and bronchodilator response of IOS indices in preschool children, their correlation with spirometry and...

BACKGROUND The influence of exercise on the pulmonary function is controverse, some studies have reported no sports influence, while the others have found positive correlation. AIM To evaluate and compare the sports influence on pulmonary function: spirometry (VC, FVC, FEV1, FEV1/FVC), lung diffusing capacity (DLCO) and coefficient of the CO gas transfer (KCO) in two elite athletes groups and...

Introduction. The European Respiratory Society, the American Thoracic and Russian Society are currently working on updating technical standards interpretive strategies for routine lung function tests. There is a search recommendations best choice of reference values, optimal limits normal severity grading detected impairments. An important step in this work standartization pulmonary tests inter...

BACKGROUND Provision of spirometry for chronic obstructive pulmonary disease (COPD) is a new requirement in primary care. Effective spirometry requires that tests and interpretations meet international criteria. AIM To assess the feasibility and usefulness of remote specialist reporting of primary care spirometry. DESIGN OF STUDY Comparison of reporting by primary care clinicians and respir...

PURPOSE Spirometry is sometimes difficult to perform in elderly patients and in those with severe respiratory distress. The forced-oscillation technique (FOT) is a simple and noninvasive method of measuring respiratory impedance. The aim of this study was to determine if FOT data reflect spirometric indices. PATIENTS AND METHODS Patients underwent both FOT and spirometry procedures prior to i...
