Statistical modelling of human blood carbon dioxide partial pressure.

This paper deals with statistical modelling of blood carbon dioxide partial pressure pCO2. The clinical measurements were carried out in the Arab Centre for Heart and Special Surgery in Amman. The statistical analysis of the results obtained demonstrates that pCO2 for arterial, venous and capillary blood have histograms approaching normal ones. Moreover, the experimental data suggest that the blood pCO2 can be expressed by a linear regression model. Making use of this regression model, the blood pCO2 population can indirectly be obtained with accuracy fulfilling clinical requirements. Therefore, this approach will not only lead to less invasive methods but will also result in decreasing the cost of projected analyser for blood gas analysis. The implementation of this proposed regression equation ensures the effectiveness of the model as an indirect method for pCO2 measurements.
