Modelling > Blood circualtion parameters > Oxygen metabolism > Saturation of arterial blood

The saturation is calculated, as an amount relation oxyhemoglobin HeO₂ to total of hemoglobin He:

(72)

This parameter is included into the equation for concentration of oxygen in arterial blood in the form of SpO₂

(71)

where factor of proportionality С_H is meaningful to oxygen capacity of hemoglobin in blood.

The parameter SpO₂is used for modelling of pathologic mode hypoxia. The main characteristic of this mode is a reduction of its value in comparison with the normal one.
