The Arterial Blood Gas (ABG) Test is a medical test that checks how well your lungs and kidneys are working by measuring oxygen and carbon dioxide levels in your blood. It helps diagnose conditions like breathing problems or kidney disease.
Here are the basic details of the Arterial Blood Gas Test.

Here is the normal range of the Arterial Blood Gas Test
ABG Test | Normal Value |
pH | 7.35 - 7.45 |
PCO2 | 35.00 - 45.00 mmHg |
Bicarbonate (HCO3) | 21.00 - 28.00 mEq/L |
Total CO2 Contents (TCO2) | 23.00 - 27.00 mmol/L |
Standard Bicarbonate (SBC) | 22.00 - 26.00 mEq/L |
Base Excess | -2.00 - 3.00 mEq/L |
PO2 | 83.00 - 108.00 mmHg |
Oxygen saturation capacity | 95.00 - 98.00 % |
Base Excess - Extracellular fluid | <0.02 mEq/L |
Hemoglobin | 13.00 - 18.00 g/dL |
Here is the Interpretation of the Arterial Blood Gas Test.
pH | Measures blood acidity/alkalinity. |
PCO2 (Carbon Dioxide) | Reflects lung function. |
Bicarbonate (HCO3) | Evaluates metabolic status. |
PO2 (Oxygen) | Measures oxygen in blood. |
Oxygen Saturation (%) | Shows how well blood carries oxygen. |
Base Excess | Indicates acid-base balance. |
Total CO2 Contents | Reflects carbon dioxide levels. |
Standard Bicarbonate | Another measure of acid-base status. |
Base Excess (Extracellular fluid) | Evaluates extracellular acid-base balance. |
Hemoglobin | Measures oxygen-carrying capacity of blood. |
Arterial Blood Gas (ABG) test interprets blood's oxygenation, ventilation, and acid-base status using various parameters within specified normal ranges.
Here are some possible causes of high Arterial Blood Gas levels:
Possible Causes | Effects |
---|---|
Hyperventilation | Excess removal of CO2; respiratory alkalosis. |
Metabolic Alkalosis | Excess bicarbonate; increased blood pH. |
Compensatory Mechanisms | Attempt to correct underlying issues. |
Hypoxia | Body may respond with increased ventilation. |
Certain Medications | Alters blood gas levels; consult a physician. |
High levels in an Arterial Blood Gas test may result from hyperventilation, metabolic alkalosis, compensatory mechanisms, hypoxia, or specific medications, leading to various physiological effects.
Here are some possible causes of Arterial Blood Gas levels:
Causes of Low Levels | Effects |
---|---|
Hypoventilation | Insufficient CO2 removal; respiratory acidosis. |
Metabolic Acidosis | Low bicarbonate; decreased blood pH. |
Compensatory Mechanisms | Response to correct underlying issues. |
Hypoxia | May worsen with inadequate ventilation. |
Certain Medications | Influence blood gas levels; consult a physician. |
Low levels in an Arterial Blood Gas test can stem from hypoventilation, metabolic acidosis, compensatory mechanisms, hypoxia, or specific medications, resulting in various physiological effects.

Here is the basic limitation of Arterial Blood Gas Test.
Here are some of the risk factors of the Arterial Blood Gas Test.
Here are the Doctor's recommendations or consult a specialist after the Arterial Blood Gas Test.
ABG Result | Doctor to Visit | Reason |
---|---|---|
High | Pulmonologist | Evaluate respiratory issues. |
Normal | No specific doctor | May not require further action. |
Low | Physician | Address acid-base imbalance. |
After an Arterial Blood Gas (ABG) test, consult a specialist based on results: a pulmonologist for high levels, a physician for low levels, and no specific doctor for normal results.
