Course Overview

This Course will provide an overview of the basic interpretation of arterial blood gas results and their relationship to metabolic and respiratory abnormalities.

Topics include:

  • A review of the physiology of respiration
  • Normal arterial blood gas ranges and what they mean
  • How to obtain a blood gas sample
  • Metabolic abnormalities and their causes
  • Respiratory abnormalities and their causes

Target audience

Health professionals in all settings, but particularly for those working in the following areas:

  • Acute care settings
  • Emergency departments
  • Critical care


Review and introduce the theoretical and practical components associated with the interpretation of arterial blood gases.


Critically ill patients are not confined to critical care units. Every day, practitioners working in acute areas encounter arterial blood gas results, which they are required to interpret. The result of an arterial blood gas sample can quickly and accurately provide reliable data on the state of a person’s acid-base balance and oxygen levels. This information can be critical in determining the speed and type of intervention required to address any abnormalities, and for assessing the effectiveness of such interventions. Arterial blood gas analysis can be complex, but this Course provides an accessible and easily understood interpretation of this advanced practice skill.

Health professionals in Australia that are registered with AHPRA are required to obtain continuing professional development (CPD) hours/points each year that relates to their context of practice, in order to comply with mandatory regulatory requirements.

Learning Outcomes
  • Describe the normal physiology of the respiratory system
  • Explain when an arterial blood gas might be needed
  • Identify normal and abnormal values of arterial blood gas results
  • Recognise specific arterial blood gas abnormalities and clinical concerns
