[The role of potassium and chlorine ions in the gas-transport function of the erythrocytes].
The research of electrolytes influence on blood gas-transport function was carried out on blood samples taken from human finger. It was shown that in the absence of blood system diseases, with pH indices, hemoglobin content, HCO3-, Na+ concentration in blood within physiological norm, partial pressure of oxygen and hemoglobin saturation by oxygen is clearly determined by concentration gradient of chlorine ions on erythrocytes membrane, that is by oxygen transport through the erythrocyte membrane, which is attended by the transfer of chlorine ions. Under these conditions there are two levels of PO2 indices and hemoglobin saturation by oxygen, depending on the concentration gradient of chlorine ions on the erythrocyte membrane, that are determined by K(+)- and Cl(-)-ions concentrations level in the blood and erythrocytes.
