Responses of HCl-CA acidified canine blood to added base solutions: concentration dependence at fixed 1:1 mixing ratio of NaHCO₃ and Na₂CO₃.

Added base solution	Conc. (mM)	pH	PCO2 (mm Hg)	[${\text{HCO}}_3^{-}$] (mM)	[Na+] (mM)	[K+] (mM)	[Cl−] (mM)
None	0	6.62	113	10.8	128	3.8	94
NaHCO3   Na2CO3	167 167	7.76	38	50.5	171	2.7	106

(1 part solution: 9 parts HCl-CA-K9-2): see also Figure 5 for corresponding plot.

A pH value in italics represents a non-BGA electrode measurement.

Dashes indicate values outside of the instrumental range of the BGA.
