Veterinary Blood Gas Interpreter

Interpret blood gas and electrolyte results for dogs and cats with clinical guidance.

Normal reference ranges differ between dogs and cats, particularly for pCO2.
Normal: 7.35-7.45. Below 7.35 = acidemia. Above 7.45 = alkalemia. Life-threatening below 7.1 or above 7.6.
Partial pressure of CO2. Dog normal: 35-45 mmHg. Cat normal: 28-35 mmHg. Reflects respiratory component.
mmHg
Bicarbonate level. Normal: 18-24 mEq/L. Reflects metabolic component of acid-base balance.
mEq/L
Partial pressure of oxygen in arterial blood. Normal: 80-110 mmHg on room air. Below 60 mmHg indicates significant hypoxemia.
mmHg
Normal dog: 140-155 mEq/L. Normal cat: 149-157 mEq/L. Used for anion gap calculation.
mEq/L
Normal: 3.5-5.5 mEq/L. Critical if <2.5 or >7.0. Affects cardiac function.
mEq/L
Normal dog: 105-115 mEq/L. Normal cat: 112-129 mEq/L. Used for anion gap calculation.
