WebDec 6, 2024 · (See "Flow-volume loops", section on 'Abnormal inspiratory loop'.) Lower airway obstruction – Airflow obstruction due to chronic obstructive lung diseases including asthma, bronchiectasis, and chronic obstructive pulmonary disease (COPD) involves the smaller bronchi in the lower airway distal to the mainstem bronchi and is not typically ... 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.
WebThe principal advantage of the flow-volume loop is that it can show whether airflow is appropriate for a particular lung volume. For example, airflow is normally slower at low … WebFlow-volume loops can be useful in chronic and intermittent stridor to show the presence of an upper airway obstruction.

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 tauranga archersWebNov 6, 2012 · When expiratory flow is maximal during tidal breathing and cannot be increased unless operative lung volumes move towards total lung capacity, tidal expiratory flow limitation (EFL) is said to occur.
