Complex Problems: Focus on Acid-Base Disorders

In this module, you'll focus on acid-base interpretation and critical care lab diagnostics. You'll work through a stepwise approach to ABGs — identifying the primary disorder, evaluating compensation using Winter's Formula, calculating the anion gap and delta gap, and determining the underlying cause. The module distinguishes high vs. normal anion gap acidosis, covers hypoxic vs. non-hypoxic causes of elevated lactate, and reviews common clinical causes of metabolic and respiratory acid-base disturbances.
