Overview

Arterial blood gases (ABGs) provide valuable information about an individual’s acid-base balance, contributing to the information required in clinical treatment decisions.

By participating in this course, you will learn what insights can be gained from arterial blood gas results and how they may assist in clinical treatment decision making.

Learning Objective

At the end of this module participants will be able to:

  • Understand the purpose of an arterial blood gas.
  • Identify the different components of an arterial blood gas including pH balance, PaO2, PaCO2, bicarbonate, and base excess, or deficit.
  • Describe pH balance, normal pH of human blood, acidosis, and alkalosis.
  • Understand the 3 ways that pH balance is maintained in the human body: pH buffering, respiratory, and renal response.
  • Understand how the body compensates in response to acidosis or alkalosis.
  • Practice putting it all together to interpret an arterial blood gas.
