Finally, the ABG explained in an easy to understand way! If you want to learn this lab test once and for all, check out this awesome video!

In this video about the arterial blood gas lab (the ABG) I start with an introduction to the basic concepts about an ABG and then talk about the components individually. I give mnemonics and other tips, followed by interpreting a few example ABGs.

HERE ARE TWO BOOKS TO EXPAND YOUR LEARNING ON ABGs
This first one is a cheap & easy, "quick read": https://amzn.to/3GpLQCT
If it looks like it's selfpublished, that's because it is (not by me)! However, these two docs do a fantastic job explaining the ABG in easy terms. It gets great reviews, and I own it in my personal library.

This second book is also a popular option for learning the ABG: https://amzn.to/3T7KDaQ.
