Arterial blood gas (ABG) analysis is an essential part of diagnosing and managing a patient’s oxygenation status and acid–base balance. The usefulness of this diagnostic tool is dependent on being able to correctly interpret the results. Disorders of acid–base balance can create complications in many disease states, and occasionally the abnormality may be so severe so as to become a life-threatening risk factor. A thorough understanding of acid–base balance is crucial for any paramedic, nurse or physician to provide the best possible care to patients.

Learning Outcomes

  • Review the concept of acidity/alkalinity:
    • pH scale,

    • Metabolic Acidosis,
    • Metabolic Alkalosis.
  • Define common ABG values:
    • pH / PaO2 / SaO2,
    • PaCO2 / HCO3 / B.E.
  • List the steps to interpret an ABG result.
  • Discuss the compensation process:
    • Respiratory compensation,
    • Renal compensation,
    • States of compensation (none, part, full)
