Arterial blood gases (ABGs) are one of the most valuable tools for assessing acid-base balance and guiding patient care — but they can feel overwhelming without a clear system. In this lesson, we’ll use the Tic-Tac-Toe method to simplify ABG interpretation, helping you quickly identify acidosis, alkalosis, and neutral states. You’ll also learn how to apply ABG results to diagnose metabolic versus respiratory disorders, connect them to patient presentations, and understand how they guide treatment decisions. By the end, you’ll have a straightforward, reliable framework for interpreting ABGs with confidence.
