HLTH 2573: Arterial Blood Gases

This in-depth course examines the basic principles of chemistry and physics related to blood gases and the physiology of respiration. The interpretation, collection and sampling of blood gases, and non-invasive measurements, are examined with particular emphasis on clinical applications.

Learning outcomes

Upon completion of this course, students will be able to:

  • Describe electrode theories and sampling techniques.
  • Describe and define characteristics of internal and external respiration.
  • Describe hypoxemia, acidosis and various types of shunting.
  • Define acid base regulation and interpret results.
  • Describe noninvasive methods of blood gas monitoring.
  • Interpret case studies.
