Correlation of spirometry and symptom scores in childhood asthma and the usefulness of curvature assessment in expiratory flow-volume curves.
BACKGROUND Spirometry, and in particular forced expiratory volume in the first second (FEV(1)), are standard tools for objective evaluation of asthma. However, FEV(1) does not correlate with symptom scores, and hence its value in the assessment of childhood asthma may be limited. Therefore, some clinicians subjectively assess the presence of curvature in the maximum expiratory flow-volume (MEFV...
متن کاملPartial flow/volume curves and airway resistances in obese subjects: new tools for investigating flow limitation?
The number of obese patients referred to our laboratory for pulmonary function tests is increasing: sleep breathing disorders, unexplained effort dyspnea, evaluations before surgical procedures are the main problems we are expected to cope with. In some patients with normal FEV1 and FEV1/VC values, we have observed an overlap between the tidal volume expiratory flow and the maximal forced expir...
متن کاملGraphic analysis of flow-volume curves: a pilot study
BACKGROUND Conventional spirometric parameters have shown poor correlation with symptoms and health status of chronic obstructive pulmonary disease (COPD). While it is well-known that the pattern of the expiratory flow-volume curve (EFVC) represents ventilatory dysfunction, little attempts have been made to derive quantitative parameters by analyzing the curve. In this study, we aimed to derive...
متن کاملFlow-volume curves and sleep-disordered breathing: therapeutic implications.
To assess the relationship of abnormal flow-volume curves during awake periods to the clinical severity of sleep-disordered breathing and the need for surgical treatment of obstructive sleep apnoea, flow-volume curves were measured in 72 adults with obstructive apnoea. Patients in whom surgery was recommended for standard clinical indications had significantly lower inspiratory flow rates (p le...
