High airway resistance

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.

WebAirway resistance is the opposition to flow caused by the forces of friction. the ratio of driving pressure to the rate of air flow. Resistance to flow in the airways depends on whether the flow is laminar or turbulent, on the dimensions of the airway, and on the viscosity of the gas. For laminar flow, resistance is quite low.
