Arterial Blood Gas (ABG) Interpretation Calculator

This medical calculator helps you analyze Arterial Blood Gas (ABG) values for a better understanding of a patient’s respiratory and metabolic status. It interprets pH, PaCO₂, and HCO₃⁻ levels to determine the type of acid-base disturbance and compensation status.

If enabled, the result will update automatically when you change any value.

Arterial Blood Gas Interpretation Formula

Formula
$$\text{pH} = \text{acid-base status} \\ \text{PaCO}_2 = \text{respiratory component} \\ \text{HCO}_3^- = \text{metabolic component}$$

Interpretation Examples:

  • Respiratory Acidosis: $$↓pH$$, $$↑PaCO₂$$
  • Metabolic Alkalosis: $$↑pH$$, $$↑HCO₃$$⁻
  • Compensation check: Is $$PaCO₂$$ or $$HCO₃⁻$$ compensating for the primary disorder?


The ABG interpretation calculator simplifies the analysis of arterial blood gases by identifying patterns in pH, carbon dioxide (PaCO₂), and bicarbonate (HCO₃⁻) levels. It’s crucial in diagnosing respiratory acidosis or alkalosis and metabolic acidosis or alkalosis. This tool is valuable for healthcare professionals in emergency medicine, intensive care, and general clinical settings to monitor ventilation, acid-base balance, and oxygenation.

    I was not given the of bicarb.
    I want to find out with these values:
    PH–7.55
    PaCo2–30
    PaO2–65
    What’s this patient’s condition?
