Summary The usefulness of venous blood in determining the acid‐base status of seriously ill animals has not been investigated. The purpose of this study was to determine whether a useful relationship exists between the acid‐base parameters of central venous and arterial blood in ill dogs. Paired arterial and venous blood samples were obtained from 46 dogs seen in the Critical Care Unit of the Veterinary Teaching Hospital of Colorado State University irregardless of their hemodynamic status. Cardiopulmonary arrest patients were not included in the study. Results of this study indicate venous blood samples can be used in the assessment of acid‐base status. Statistical significance was seen in comparing arterial versus venous pH (P < 0.001), PCO2 (P < 0.001), and bicarbonate (P < 0.001). Linear regression equations will allow one to predict arterial values from venous samples.
