Related to alkalemia: alkalotic


abnormal alkalinity, or increased pH, of the blood.


A decrease in H+ ion concentration of the blood or a rise in pH.
[alkali + G. haima, blood]


An increase in pH in the blood due to alkalosis.

The most common cause of alkalaemia is hyperventilation which results in decreased carbon dioxide, leading to respiratory alkalosis; less common is prolonged vomiting, resulting in loss of hydrogen ions, dehydration and heavy milk consumption.


A decrease in H-ion concentration of the blood or a rise in pH, irrespective of alterations in the level of bicarbonate ion.
Synonym(s): alkalaemia.
[alkali + G. haima, blood]
