Abstract
Blood samples were collected by microhematocrit tube from the postterior medial margin of the shaved, but otherwise untreated, canine ear. Acid-base and blood gas values of these samples were compared with the values of samples obtained simultaneously from the carotid artery. The arterialized nature of capillary blood from the canine ear was demonstrated under various degrees of chemical restraint and during conditions of extreme hypoxic acidosis to hyperventilatory alkalosis. Once a week determinations of acid-base and blood gas status with such arterialized capillary blood from a group of awake dogs showed within-subject variance to be significantly less (P .ltoreq. 0.05) than between-subject variance; uniqueness of individual dogs was reliably revealed. Breed differences for acid-base and blood gas characteristics were demonstrated.
