Course Overview

Refresh your knowledge of basic arterial blood gas (ABG) results interpretation and their relationship to metabolic and respiratory abnormalities with this Ausmed Course, now!

  • Components of the arterial blood gas analysis
  • Factors that may affect arterial blood gas levels
  • Classifying acid-base disorders and their causes
  • Compensatory mechanisms
  • Venous blood gas analysis

There are text books devoted to arterial blood gas interpretation, however, there’s no point going into complex biochemistry if you don’t have a solid understanding of the basics.

Most of the time, basic ABG interpretation is all that is needed, and having the skill to recognise a problem, a potential cause, and maybe even a treatment, can save someone’s life.

Some other oversimplified methods of understanding ABGs may help diagnose the overall arterial blood gas but they fail in helping us understand what it means for our patient.

This course aims to find a balance between giving learners the confidence to relate what they are interpreting back to their patient, while using a simple to understand five-step method.


The purpose of this Ausmed Course is to give learners the confidence to relate meaning from arterial blood gas results back to their patient using an easy to understand method.
