Can flow-volume loops be used to diagnose exercise-induced laryngeal obstructions? A comparison study examining the accuracy and inter-rater agreement of flow volume loops as a diagnostic tool.

Pre- and post-exercise flow-volume loops are often recommended as an easy non-invasive method for diagnosing or excluding exercise-induced laryngeal obstructions in patients with exercise-related ...

Flow volume loop during the acute attack may also show some inspiratory flattening consistent with variable extrathoracic obstruction, but, alternatively, the flow volume loop may show both ...

Exercise tidal flow met or exceeded the expiratory boundary of the maximal flow volume loop over 72% of the expiratory volume, which indicated expiratory flow limitation.

The imaging assessed regional ventilation (oxygen flow), flow-volume loop correlation metric (FVL-CM), quantified perfusion (blood flow), ventilation and perfusion defect percentages, and ...

A spirometry flow-volume loop demonstrated fixed upper airway obstruction. Fiberoptic bronchoscopic examination revealed a circumferential inflammatory process partially occluding the tracheal lumen.
