Response of HCl-acidified canine blood to Na₂CO₃ solutions: concentration dependence. Measured blood gas parameters (A) pH, (B) PCO₂, (C) [${\text{HCO}}_3^{-}$], and (D) [Na⁺] of HCl-CA-K9-2 acidified canine blood as a function of [Na₂CO₃] of added base solution. One part of disodium carbonate solution is added to nine parts of acidified canine blood. In each panel, the reference parameter value of acidified blood without base treatment corresponds to the point at [Na₂CO₃] = 0 mM and the dashed line. Solid line in (A) is a linear least squares fit (see text).
