BACKGROUND Some technologists worry that patients with very severe lung disease are unable to complete several spirometry maneuvers, which require considerable effort. METHODS We retrospectively selected all spirometry tests with an FEV1 < 35% predicted done by adult subjects sent to our pulmonary function laboratory during a 3-y period. We determined the rates and correlates of poor quality ...
Chronic obstructive pulmonary disease is easily detected in its preclinical phase, using office spirometry. Successful smoking cessation prevents further disease progression in most patients. Spirometry measures the ratio of the forced expiratory volume in the first second to the forced vital capacity (FEV(1)/FVC), which is the most sensitive and specific test for detecting airflow limitation. ...
BACKGROUND The Global Initiative for Chronic Obstructive Lung Disease (GOLD) underlines that spirometry is the gold standard as the most reproducible, standardised, and objective way of measuring airflow limitation in the diagnosis and assessment of Chronic Obstructive Pulmonary Disease (COPD). However, studies undertaken in different countries have suggested a widespread underuse of spirometry...
Material and methods. A questionnaire was completed simultaneously by professionals responsible for spirometry in all of the primary health care centers in Navarre. Data were collected on availability, model of spirometer, frequency of use, calibration, methods, personnel responsible for testing, and training of personnel. Then, baseline spirometry without a bronchodilator test was performed in...
S tanbrook and Kaplan have previously suggested that " physicians who do not use spirometry for their asthma patients should not be managing asthma. " 1 They have put forth the notion that asthma management without spirometry testing would be considered failing to maintain an adequate standard of care, and that most primary care physicians " need to make testing available in their own offices. ...
BACKGROUND Spirometry is a cost-effective diagnostic tool for evaluation of lung function and for case-finding in a resource-limited setting. The acceptance of this test depends on the awareness of its indications and the ability to interpret the results. No studies have assessed the knowledge of spirometry among Nigerian doctors. The aim of this study was to evaluate the current knowledge, awa...
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...
OBJECTIVES Konstantin Buteyko, M.D., Ph.D., claimed that breath holding time (BHT) can be used to detect chronic hyperventilation and that BHT predicts alveolar CO(2) (Pa(CO(2))) according to his patented mathematical formula. The Buteyko Breathing Technique (BBT) is believed to correct chronic hyperventilation as evidenced by increased BHT. In this study, we test Buteyko's claims and explore t...
Asthma and chronic obstructive pulmonary disease (COPD) are highly prevalent in older people [1–4]. This well established fact has not, however, overcome the problem of underdiagnosis or misdiagnosis of both conditions in old age, with the inevitable effect on morbidity , and possibly mortality [1, 5]. Properly performed spirometric measurements of Forced Expiratory Volume in 1 second (FEV1) an...
