Tests of Ventilatory Capacity
Jehu Iputo
PPTX9 pages2.1 MB
The document outlines the measurement of forced expiratory volume (FEV1) and forced vital capacity (FVC) and describes how to interpret normal, obstructive, and restrictive patterns on forced expiration. It details the calculation of forced expiratory flow (FEF25–75%) and the use of expiratory flow–volume curves. Diagrams illustrate dynamic airway compression during forced expiration and the changes in PO₂ along the pulmonary capillary. The material also covers gas exchange during hypoventilation and lists causes of hypoventilation.
