Acid Base: Part II
Posted by Scott D. Weingart, MD FACEP in Critical Care on April 25th, 2011
Part I was hard; Part II is even tougher. But I think there is light at the end of the tunnel. In this episode we go through the math of an acid-base scenario. You will begin to understand the quantitative approach, but you’ll also understand the standard approach. We will discuss why the “normal anion gap” is a myth.
Acid Base: Part I
Posted by Scott D. Weingart, MD FACEP in Critical Care on April 11th, 2011
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.
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.
