WebMay 22, 2016 · The position of the tidal flow-volume loop is determined by the IC and the tidal flow-volume loops that precede and follow the IC maneuver will be recorded along with the IC maneuver. Although CPET system software will usually attempt to measure and report the EELV and IC automatically, this always needs to be verified. WebAug 23, 2024 · Flow-Volume Loops. Normal. Peak expiratory flow of ~8L.s-1 Initial flow is highest as the increased lung volume increases the calibre of lung airways, reducing airways resistance. This is called the effort dependent part of the curve; Flow tails off later in expiration . Lungs collapse, and airway calibre falls; Small airways are compressed
