Spirometry standards and FEV1/FVC repeatability

Adherence to acceptability and repeatability criteria for spirometry in complex lung function laboratories.

BACKGROUND Few published data exist for adherence rates to spirometry acceptability and repeatability criteria in clinical respiratory laboratories. This study quantified adherence levels in this setting and observed changes in adherence levels as a result of feedback and ongoing training. METHODS Two tertiary hospital-based, lung function laboratories (L1 and L2) participated. Approximately ...

Official American Thoracic Society technical standards: spirometry in the occupational setting.

PURPOSE This document addresses aspects of the performance and interpretation of spirometry that are particularly important in the workplace, where inhalation exposures can affect lung function and cause or exacerbate lung diseases, such as asthma, chronic obstructive pulmonary disease, or fibrosis. METHODS Issues that previous American Thoracic Society spirometry statements did not adequatel...

Spirometry pattern and respiratory symptoms in sweepers

Introduction: Multiple and sometimes contradictory evidence exists on the relationship between dust exposure and respiratory symptoms with pulmonary disorders. The study was conducted to examine the effects of chronic exposure to street dust on the pulmonary parameters and respiratory complaints in sweepers. Methods: This cross-sectional study was conducted on 100 sweepers working in district ...

Spirometry and Bronchodilator Test

Spirometry is a physiological test for assessing the functional aspect of the lungs using an objective indicator to measure the maximum amount of air that a patient can inhale and exhale. Acceptable spirometry testing needs to be conducted three times by an acceptable and reproducible method for determining forced vital capacity (FVC). Until the results of three tests meet the criteria of repro...
