Airway resistance can also vary between inspiration and expiration: In emphysema there is destruction of the elastic tissue of the lungs which help hold the small airways open. Therefore during expiration, particularly forced expiration, these airways may collapse causing increased airway resistance. 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. ray gallo west islip

WebUpper airway resistance syndrome (UARS) is a condition that was first identified and described at Stanford University.
