ABG Interpretation for Nurses: Key Info for Arterial Blood Gases (RNs & RRTs)

Arterial blood gases (ABGs) are a challenging lab test for healthcare professionals such as nurses, MDs, and RRTs to comprehend fully. While normal results are provided, understanding goes beyond just the numbers. Questions may arise, such as the significance of a specific blood pH or the origin of bicarbonate levels. To accurately interpret ABGs, it is crucial to grasp these components and other values.

ABGs examine oxygen levels, carbon dioxide levels, blood acidity (pH), oxyhemoglobin saturation, and bicarbonate levels in arterial blood. Advanced blood gas analyzers can also provide information on methemoglobin levels, carboxyhemoglobin levels, and sometimes hemoglobin levels. These values offer valuable insights for patient care in settings like the intensive care unit (ICU) and other hospital environments.

For those unfamiliar with terms like oxyhemoglobin saturation, fear not! By the time you finish this guide, you will be well-versed in interpreting ABGs. This comprehensive resource covers the following topics:
