Name two factors that can reduce lung volume

Witryna17 sty 2024 · Resistance in an airway is inversely proportional to the radius of the airway. However the ratio for this relationship is not 1:1. Below is the equation for calculating airway resistance (R). R=8 (Length×Gas Viscosity) (πr4)R=8 (Length×Gas Viscosity) (πr4) The most important part of this formula is radius of the airway ( r ). WitrynaInitially as can be seen from the above curve at lower lung volumes the compliance of the lung is poor and greater pressure change is required to cause a change in volume. This occurs if the lungs become collapsed for a period of time. At FRC compliance is optimal since the elastic recoil of the lung towards collapse is balanced by the …
