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.
The fall in PCO2 causes a compensatory fall in plasma HCO3- concentration as was decribed previously. The causes of Respiratory Alkalosis are shown in the table below. It is very commonly induced by what the body or patient perceives as a stressor.The stressor which is often associated with anxiety, pain, and infection stimulates the CNS leading to hyperventilation.espiratory Alkalosis. Respiratory Alkalosis is an acid base disturbance characterized by elevated arterial pH, hyperventilation resulting in a low pCO2 and a usually compensatory decrease in plasma HCO3- concentration.
