FAQs About ABGs Interpretation
What is an ABG?
An arterial blood gas (ABG) test measures the pH, oxygen (PaO₂), carbon dioxide (PaCO₂), and bicarbonate (HCO₃⁻) in the blood.
What are normal ABG values?
- pH: 7.35–7.45
- PaCO₂: 35–45 mmHg
- HCO₃⁻: 22–26 mEq/L
What does a high PaCO₂ mean?
It often indicates respiratory acidosis, usually due to hypoventilation.
Is this calculator accurate for compensated ABGs?
Yes. It identifies whether the body is compensating and offers a simplified interpretation.
Conclusion
Use our ABG interpretation calculator to simplify complex acid-base analysis. This easy tool provides fast results, guiding you to better decisions in seconds.
How to calculate ABGs?
To calculate ABGs (Arterial Blood Gases), you need values for pH, PaCO₂, and HCO₃⁻. These values help determine if the patient is in acidosis or alkalosis and whether it’s respiratory or metabolic in origin. Our ABG calculator does this instantly based on your input.
How to calculate ABG step by step?
Start with the pH to assess acid-base status (acidosis or alkalosis).
Then evaluate PaCO₂ and HCO₃⁻ to determine if the issue is respiratory or metabolic acidosis or alkalosis.
Finally, check for compensation and interpret accordingly. Our tool automates this process for quick interpretation.
What is a calculated ABG value that indicates a disorder?
A calculated ABG value showing pH < 7.35 suggests acidosis, while pH > 7.45 suggests alkalosis.
If HCO₃⁻ is abnormal, the disorder is metabolic.
Our calculator highlights the primary disorder and type instantly.
If PaCO₂ is abnormal, the disorder is respiratory.
