Rounded inspiratory loop on spirometry
Webloop is performed during both expiration and inspira-tion; by convention, expiratory flow is positive and inspiratory flow is negative. The normal flow-volume loop has a characteristic configuration (Figure 2). Flow-volume loop deviations Three characteristic deviations from the normal flow-volume loop suggest various forms of upper airway WebAug 21, 2016 · Chapter 2Spirometry Spirometry is probably the most commonly performed lung function test. Spirometry measures flow and volume components of ventilatory function and is measured under relaxed or forced conditions. Forced vital capacity (FVC) manoeuvres provide information regarding dynamic changes in lung volumes, whereas …
