This reflex results in regulation of blood pressure, especially if it is highly elevated or severely depressed; however, the reflex is usually elicited in systolic blood pressures over 150–170 mmHg; the other part of the reflex is not often seen when the systolic blood pressure is below 50–60 mmHg.
