[Characteristics of hemodynamics in the right and left common carotid arteries in the cat].

The correlation between volumetric and linear blood flow rate, recorded synchronously in two common carotid arteries, has been analyzed in anesthetized cats after repeated injections of adrenaline and noradrenaline (2-10 micrograms/kg) and in intact animals. No correlation has been found in the volumetric blood flow parameters; in the right artery the parameters were more dependent on the diastolic flow. In the right artery, a negative correlation with BP was observed, while in the left artery, the correlation was noted with heart rate. The results show great autoregulatory and myogenic activity of the right artery vascular bed.
