Yeah i agree diagrams and pharma are probably the worst thing about studying for USMLE lol....maybe read a little about it from wikipedia it says that basically the concept is important and it's never used really in the clinical setting

Here's the link

http://en.wikipedia.org/wiki/Davenport_diagram

Hope this helps.

Hi
This is from another user that explained to me a different thread!

Just remember the basic rule when approaching any diagram, LOOK AT THE AXIS. In the Davenport, X axis is the pH, Y is the HCO3 and the CURVE LINES are the PCO2.

My approach to any pH imbalance:
First determine how is the pH (acidosis or alkalosis), then see if there's any respiratory or metabolic contribution (is the PCO2 high or low?, is the HCO3 high or low?); now put the "first name" (respiratory or metabolic) by determining whether PCO2 or HCO3 is causing the corresponding pH. Finally see if there's any compensation.
You can see the thread here - Davenport Diagram ?

lol, I had seen this in my FA and thought it was weird! Perfectly good way to mess up a concept, which seems in my mind atleast to make the mle guys love this. Didnt know it was called the Davenport diagram. So what I do, and which doesnt work most of the time/takes more time than perhaps needed is that I had studied acid base from goljan chapter 3 (you can forget the equations there though!) and that concept about the acidosis etc etc etc helps me pretty well. (I'm not sure though if we are talking about the same thing, if not, then I seriously need to look at this diagram!) But I usually trust those few pages on goljan, didnt even bother reading the Kaplan phys section and I for one seemed to think that was adequate.
It would be nice to hear from better prepared people though, my prep isnt exactly great!

hello,
I'd suggest you guys review the Kaplan videos on Renal. It was neatly explained. After watching it I actually understood Davenport on FA.

Acid base balance is an easy concept, Davenport did not have to come up with the dame graph, which is never used by clinicians!
