Effects of short-term hypoxic hypoxia on the sodium and potassium homoeostasis in humans.
The effect of a short-term hypoxic hypoxia on the electrolyte metabolism has by now scarcely examined. Disposable results are not consistent. With the help of ionosensitive electrodes sodium and potassium concentrations in blood, serum, urine, and erythrocytes have been studied before and after a hypoxic hypoxia (PaO2) in healthy subjects. Blood and plasma concentrations of sodium and potassium were unchanged. Natriuria and kaliuresis increased under the hypoxia exposure. Intraerythrocytic potassium concentration decreased significantly. Possible causes and the diagnostic value are discussed.
