Excerpt
Sir: In their recent paper, Doberer et al. [
1] discuss the pathophysiology of dilution acidosis using a combination of simulations based on Stewart’s algorithm and simple experiments. Since acidosis is only found in open systems, they conclude that the classical model is confirmed, in which acidosis is thought to result from dilution of [HCO
3 −] at unchanged pCO
2. The notion of dilution must entail the direct predictability of the [HCO
3 −] in a mixture from the respective volumes and [HCO
3 −] in the constituent fluids. …
