What is the primary purpose of an arterial blood gas test?
What is the primary purpose of an arterial blood gas test?
- To assess liver function
- To diagnose cardiovascular diseases
- To measure blood pressure
- To evaluate the balance of oxygen and carbon dioxide in the blood (correct)
What is the difference between an ABG test and a blood gas analysis?
What is the difference between an ABG test and a blood gas analysis?
- Blood gas analyses are used to diagnose respiratory diseases, while ABG tests are used for circulatory diseases
- Blood gas analyses use a sample from a vein, while ABG tests use a sample from an artery (correct)
- ABG tests are only done in emergency situations
- ABG tests are more accurate than blood gas analyses
What is the potential consequence of low blood oxygen levels?
What is the potential consequence of low blood oxygen levels?

Study Notes
Arterial Blood Gas (ABG) Test
- Measures oxygen and carbon dioxide levels in blood, as well as blood's pH balance
- Requires a blood sample from an artery, not a vein
- Typically ordered in emergency situations
Importance of Oxygen and Carbon Dioxide Levels
- Body tightly regulates oxygen and carbon dioxide levels to prevent hypoxemia (low blood oxygen) and related serious conditions
- Low blood oxygen levels can damage brain, heart, and other organ systems
Purpose of Arterial Blood Gas Tests
- Helps healthcare providers interpret conditions affecting respiratory system, circulatory system, and metabolic processes
Blood Gas Analysis
- Differs from ABG test, using blood sample from anywhere in circulatory system (artery, vein, or capillary)

Description
Learn about the ABG test, which measures oxygen and carbon dioxide levels, as well as pH balance, in your blood. This test is typically ordered in emergency situations and requires a sample from an artery.
