[Educational programs on ventilation-perfusion ratio].
The paper describes a learning programme for calculating the characteristics of arterial blood from the ventilation-perfusion ratios in the lungs by using a three-variable mathematical model of the lung. The lungs are presented as a set of three components which differ in ventilation and perfusion: 1) a fraction of ventilated and O2-perfused alveoles; 2) a fraction of non-perfused and ventilated alveoles; 3) a fraction of unventilated and non-perfused alveoles. Results of calculations are provided.
