CO2

The Biorex Diagnostics Bicarbonate (CO₂₎  assay is intended for the quantitative determination of CO2 from serum. Measurement of total CO₂ as part of an electrolyte profile is useful mainly in evaluation of HCO₃ ^– concentration in assessment of acid-base disorders such as respiratory acidosis and metabolic alkalosis. Increased blood C0₂ (hypercapnia) causes respiratory acidosis, CO₂ rises with decreased alvedar ventilation due to decrease of the lungs or bronchial tree, or breathing C0₂ enriched air. Depression of the overall lung capacity by certain drugs may lead to retention of C0₂.
