Flow vol loop
WebFlow-volume loops can be useful in chronic and intermittent stridor to show the presence of an upper airway obstruction. Abnormal flow-volume loop findings generally require follow up with CT or laryngoscopy. Treatment of Stridor Definitive treatment of stridor involves treating the underlying disorder. 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
