VIDEO FOR EDUCATIONAL PURPOSES. INTERPRETATION OF ARTERIAL BLOOD GAS TEST IN 4 STEPS: In this video I give you a lesson to learn how to interpret an ARTERIAL BLOOD GAS TEST in a very basic way. The interpretation is done in 4 steps: 1) Determine if it is acidosis or alkalosis. 2) Determine the component (metabolic or respiratory). 3) Calculate the anion GAP. 4) Estimate the compensation. In addition, I briefly review the causes of the 4 acid-base balance disorders, definition of pH, and at the end exercises are done to reinforce the concepts learned. I hope you like the video, leave comments if there is any question or correction you want to make. Sincerely, Dr. P. Baelish. Twitter: @BaelishDr
