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 ...

Spirometry with FVL measurement is a vital component of the patient evaluation for respiratory symptoms, and when a properly performed FVL test is abnormal it should prompt a thorough investigation.

Electrical impedance tomography (EIT) is a non-invasive diagnostic tool for evaluating lung function. The objective of this study was to compare respiratory flow variables calculated from thoracic EIT ...

Recent advances in artificial intelligence (AI) have enabled more sophisticated analyses of full spirometric curves, including flow-volume loops and volume-time curves, facilitating the identification ...

The convex inflection on flow-volume curves, sometimes known as the “knee,” is assumed to signify tracheomalacia. However, there was limited information on the patterns of spirometry curves in ...

To evaluate the effect of nebulized albuterol on tidal breathing flow-volume loops in infants with bronchiolitis due to respiratory syncytial virus. Tidal breathing flow-volume loops were obtained ...

This application note provides an introduction to spirometers and their basic functions. It discusses both laboratory units and portable devices for point-of-care testing, and offers guidance on ...
