Peripatetic and always intellectually restless, Darren Wake has pursued varied careers in journalism, media production, academic philosophy and nursing. As a nurse, he worked in the speciality areas of critical care, community care, remote area healthcare and education. As a formally qualified academic philosopher Darren taught undergraduate units in law and ethics in healthcare, although his principle research focus revolved around logic and the philosophy of language. Darren’s media production output can be found scattered about the Ausmed website and in his long forgotten days as a word monkey, he wrote for European publications such as The Scotsman, The Great Outdoors, Country Walking and The Times. In 2014 Darren consulted to the Department of Health for the development of Consumer Directed Care policy and guidelines for remote area communities in the Northern Territory. These days he is the managing editor of a small independent publishing company based in the United Kingdom, and lives in Tasmania. In his spare time, Darren is currently studying a formal course in celestial navigation, just in case the inevitable zombie apocalypse messes with the world’s GPS satellite system.

The educator has made a very brilliant and engaging slides on the interpretation of Arterial Blood Gases. The education was really helpful to reinforce my understanding of interpreting ABG gases. Case scenarios was really helpful to reflect upon the cases that we face almost on daily basis. Highly recommended.

Course Overview

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.
