1 Unaudited Financial Results for the Quarter ended 31st March, 2015 along with Limited Review Report. 2  Date: 14th May, 2015.
The ABG values one would see with respiratory alkalosis would be: pH > 7.45; PaCO2 < 35 mm Hg; and HCO3 < 22 mEq/L if compensating. In acute respiratory alkalosis the compensation is to lower the serum HCO3 by 2 mEq/L for every 10 mmHg reduction in PaCO2.
There are two types of respiratory alkalosis: chronic and acute as a result of the 3-5 day delay in kidney compensation of the abnormality. 1  Acute respiratory alkalosis occurs rapidly. 2  For every 10 mmHg drop in PCO2 in arterial blood, there is a corresponding 2 mEq/L drop in bicarbonate ion due to acute compensation. Chronic respiratory alkalosis is a more long-standing condition. 2  For every 10 mmHg drop in PCO 2 in arterial blood, there is a corresponding 5 mEq/L drop in bicarbonate ion. 3  The drop of 5 mEq/L of bicarbonate ion is a compensation effect which reduces the alkalosis effect of the drop in PCO 2 in blood.
