Web12 de set. de 2024 · Airway resistance depends on the air viscosity, density, and length, and radius of airways. Except for the radius of the airway, all other variables are relatively constant. Thus, airway resistance can undergo physiologic alteration by changes in the radius of the airway bronchus. Compliance Diagram Webairway resistance from some obstructive process, the flow scalar will show a decreased peak expiratory flow and a prolonged time for the expiratory curve to return to a baseline of zero flow (Fig. 2b) [5†]. All of this represents that the resistance to airflow is limiting how fast and how much volume the lung empties. Conversely, when com-
