A rterial blood gas (aBG) evaluation is a point-of-care diagnostic test used to evaluate oxygenation, ventilation, and acid-base balance in critically ill patients, particularly dogs. The partial pressure of oxygen in arterial blood (Pa o 2 ) is
risk factors have been previously reported in prairie dogs and other rodent species. 4,5 Measurement of venous blood gas analytes may be important when evaluating the overall health status of an animal. 7 Assessment of these analytes can help to
Anaerobic collection of blood into a GS and storage in ice water is the reference method for the collection and storage of blood samples for blood gas and acid-base analysis. 1,2 Glass syringes are impermeable to O 2 and CO 2 , and storage at 0
because changes in sodium, potassium, and chloride concentrations help to guide IV fluid therapy in an emergency setting and can be readily measured by both blood gas and reference chemistry analyzers. We aimed to compare the results provided by each

Serial analysis of blood gas values and measurement of blood lactate concentrations have been used as indicators of physiologic distress in many species, including fish. 1–7 In critically ill human patients, high plasma lactate concentrations may
SUMMARY
Twenty-four healthy dogs > 8 years old were recruited. In each instance, arterial blood gas tensions were analyzed. The alveolar-to-arterial oxygen gradient (P[a-a]o 2) was calculated to assess adequacy of pulmonary gas exchange. Thoracic radiographs were evaluated to ensure lack of visible signs of pulmonary disease and that lung features were similar to those in aged dogs of previous reports. Unlike findings in aged human beings, arterial partial pressure of oxygen (Pao 2) was not decreased in this group of aged dogs (mean ± sd, 102.9 ± 7.8 mm of Hg). Similarly, P[a-a] o 2 also was not increased. The thoracic radiographic findings were consistent with those of previous reports of pulmonary changes in aged dogs. The extent of radiographic abnormalities and the Pa o 2 were not correlated.
