Abstract
We have developed an iterative computer-based algorithm which determines Pso while avoiding direct inversion of the relationship between blood oxygen partial pressure and oxyhemoglobin saturation. Blood sample measurements and the value of P50 are used, together with carboxyhemoglobin data, as necessary, to calculate blood oxyhemoglobin saturation and oxygen content.
