FAQs About ABG Calculator Interpretation
An arterial blood gas (ABG) test measures the pH, oxygen (PaO₂), carbon dioxide (PaCO₂), and bicarbonate (HCO₃⁻) in the blood.
pH: 7.35–7.45
PaCO₂: 35–45 mmHg
HCO₃⁻: 22–26 mEq/L
It often indicates respiratory acidosis, usually due to hypoventilation.
Yes. It identifies whether the body is compensating and offers a simplified interpretation.
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.
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.
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.
