explain why HCO3- levels can be calculated from pH and pCO2 levels
Solution
pH is defined as the negative log of the Hydrogen ion concentration: -log[H+].
(also, pH=pK+log [HCO3]/ 0.03 x pCO2). The pH is the product of two components,
respiratory and metabolic, thus allowing for the effect of the pCO2, ie, any change in the pH
unexplained by the pCO2 resulting ina metabolic abnormality.
CO2 and water combine to form carbonic acid or H2CO3, present with concentrations of
bicarbonate (HCO3-)and hydrogen ions (H+) in equilibrium amounts. A change in the
concentration of the reactants on either side of the equation affects the subsequent direction of
the reaction. Eg., a rise in CO2 will also raise carbonic acid formation (H2CO3) which leads to
raised levels of both HCO3- and H+ (\\pH)..
