Circulating quantities of sodium, potassium, calcium, inorganic phosphorus, and magnesium in serum of healthy newborn infants. 1976

K Ludmány

The main serum ions were determined in healthy, full-term newborn infants having different plasma volumes. The serum sodium, potassium, and calcium concentrations were found to be constant, thus their circulating quantities were dependent on the actual plasma expansion. The serum inorganic phosphorus and magnesium concentrations were found to be inversely related to the plasma volume and therefore the circulating total quantities of these ions remained constant in different expansion of the plasma volume.

D011188	Potassium	An element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE.
D001810	Blood Volume	Volume of circulating BLOOD. It is the sum of the PLASMA VOLUME and ERYTHROCYTE VOLUME.	Blood Volumes,Volume, Blood,Volumes, Blood
D002118	Calcium	A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
