Arterial Blood Gases (ABGs)

In this lesson, we will review arterial blood gases, or ABGs, and show how they are used to identify certain respiratory acid-base imbalances and determine oxygenation and perfusion.  We will also look at the important role the nurse plays before and after this procedure in preventing complications.

1. List normal parameters for arterial blood gas test components
