A study of the influence of blood ion balance on thermoelectric properties

The work presents the results of studies of thermoelectric effect in physiological fluids of animals, as well as in their model solutions. Measurements were carried out on blood samples, as well as on Ringer's solutions isotonic to blood plasma. The swine blood chosen as an object of research is the closest in ionic composition to human blood. In the process of sample preparation, an imbalance between concentrations of sodium and potassium cations in relation to normal proportions was artificially formed. The influence of potassium ion concentration on electrical conductivity and the value of thermoelectric EMF was detected. The obtained results can be used to detect blood ion balance disorders, namely, the diagnosis of hypokalaemia and hyperkalemia.
