refers to a condition reducing
Hydrogen Ion concentration of
Arterial Blood Plasma . Generally alkalosis is said to occur when arterial
PH exceeds 7.45.
Results from increased
Alveolar respiration (hyperventilation) leading to decreased plasma
Carbon Dioxide concentration. This leads to decreased hydrogen ion and
Bicarbonate concentrations.
There are two types of respiratory alkalosis: chronic and acute. In chronic respiratory alkalosis for every 10 mM drop in pCO2 in blood, there is a corresponding 5 mM of bicarbonate ion drop. The drop of 5 mM of bicarbonate ion is a compensation effect which reduces the alkalosis effect of the drop in pCO2 in blood.
In acute respiratory alkalosis, there is no compensational affect. During acute repiratory alkalosis, the person will lose consciousness where the rate of ventilation will resume to normal.
Results from altered metabolism.
Results in decreased hydrogen ion concentration leading to increased bicarbonate and carbon dioxide concentrations.
Metabolic alkalosis most commonly occurs when a person vomits profusely, as doing so depletes the body of H+ ions, which leads to a profusion of bicarbonate in the body.
Results from
Diarrhea .
