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]


/al·ka·le·mia/ (al″kah-le´me-ah) increased pH (abnormal alkalinity) of the blood.


Etymology: Ar, al + galiy, wood ash; Gk, haima, blood
increased pH of the blood, above the normal range of 7.35 to 7.45. Also spelled alkalaemia.


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]


abnormal alkalinity, or increased pH, of the blood. See also alkalosis.
