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 mechanisms responsible for this compensation to respiratory alkalosis; 1) rapid cell buffering and 2) a decrease in net renal acid excretion. As in respiratory acidosis, these responses occur in different moments of time, distinguishing acute respiratory alkalosis from chronic respiratory alkalosis.espiratory alkalosis is caused by an elevation in the frequency of alveolar ventilation and more importantly tidal volume that result in an increase in minute ventilation.
