[The dependence of the blood pH, PCO2 and PO2 values measured on the microanalyzer on the hematocrit index during hemodilution and hemoconcentration].

The arterial blood's pH, PCO2 and PO2 were shown to depend on the value of hematocrit in erythrocyte suspension in rats. The dependence can be described by the equation of linear regression except the oxygen tension value within its physiological range. A table of corrections is presented for the values of the blood's pH, PCO2 and PO2 for taking into consideration the factor of altered hematocrit in studies of acute anemias.
