Enter the patient's pH value (normal: 7.35–7.45)
Enter PaCO₂ in mmHg (normal: 35–45)
Enter HCO₃ in mEq/L (normal: 22–26)
Enter PaO₂ in mmHg (normal: 80–100)
Click 'Interpret ABG' to see the result
A pH < 7.35 indicates acidemia; pH > 7.45 indicates alkalemia
Primary respiratory disorders are determined by PaCO₂ changes
Primary metabolic disorders are determined by HCO₃ changes
Compensation is never complete — pH rarely returns fully to normal
PaO₂ < 60 mmHg on room air meets criteria for supplemental oxygen
