A blood condition characterized by excessive alkalinity (excessively high pH). A blood pH greater than 7.4 is considered alkaline and rep represents an accumulation of hydroxide ions and depletion of hydrogen ions, CARBON DIOXIDE, and CARBONIC ACID. The body is exquisitely buffered to keep blood pH slightly alkaline, within a very narrow range, 7.35–7.45. However, this equilibrium can be shifted by loss of STOMACH ACID through vomiting; by the consumption of alkaline medications such as those used to treat ulcers; and by rapid breathing (hyperventilation), which rapidly decreases the body’s stores of carbon dioxide. The body compensates for alkalemia and reestablishes normal blood pH by slowing the respiration rate (breathing); this increases the level of carbon dioxide in the blood, which spontaneously forms more carbonic acid. The KIDNEYS can compensate for elevated pH by excreting alkaline urine.
