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.
通气灌注不均等借助用Basic语言编写的程序进行分析，该程序易于在个人计算机上实现。对于一个气体交换单元，主要方程描述了氧气的质量平衡，假设不存在扩散障碍。使用大量这样的单元可以计算通气血流分布异常时的动脉血氧分压。进行了若干模拟以研究通气/血流比值的局部变化和吸氧对动脉血氧分压的影响。
