I have spoken about it for a while, but I’ve finally gotten it done: the acid-base podcast. The podcast is going to be in 3 or 4 parts. They are segmented from a lecture I gave to my residents recently. Part II discusses the mathematics of acid base and Part III goes through actual problems. Part IV then discusses the acid-base of administered solution.
This lecture discusses a quantitative approach to acid base management. This is also known as the Fencl-Stewart approach, the strong-ion approach or the physicochemical approach. It provides explanations for why acid base disorders occur in human pathophysiology. The classic method used in the USA is the Henderson-Hasselbalch (misspelled on my slides) approach. I find this method to provide no comprehensive explanation for why things are as they are. Through the quantitative approach, you can also understand the H&H approach and continue to use it with new insight.
This first part deals with the preliminaries. Part II will go into clinical applications.
After listening to the podcast, I recommend reading this article:

For the next part of the series, you will need a print out of this sheet:
