Can you achieve “arterialization” of the venous blood in a dog with normal cardiovascular status by heating its paw to 37C (=98.6F) for measurement of blood gas variables?
In both human and veterinary medicine, venous blood samples have been used to estimate acid-base balance as an alternative to arterial blood samples. In human medicine, a technique called “arterialization” of the dorsal hand vein is established, where warming the hands to 42-43°C (=107-109.4F) for 10-15 minutes makes venous blood more similar to arterial blood.
