Abstract
Ventilation perfusion inequality, is analysed with the help of a program written in Basic language, easily implemented on a personal computer. For a gas exchange unit, the main equation describes a mass balance for oxygen, assuming absence of diffusion barrier. The use of a large number of these units allows for calculation of the resulting arterial PO2 in case of abnormal ventilation blood flow distribution. Several simulations are made to study the effect of local variations of VA/Q ratio, and oxygen inhalation upon arterial PO2.
