The reactive hyperemic response pattern has been compared in young dogs (3 to 6 months) and old dogs (11 to 17 years). The general characteristic pattern in the young animal was one of maximal flow height and flow pulse immediately following release of the arterial occlusion. There was minimal flow pulse narrowing during the overall response time. Typically, the old animal hyperemic pattern showed a very much reduced flow pulse during the early postocclusive period. Systolic flow height was minimally increased, if at all, during this same period of time. The old dog hyperemic response was modified, by the injection of vasodilator compounds, so that it closely approximated the response of very young dogs.
