A decrease in blood pressure triggers a baroreceptor reflex that leads to increased ventilation. What is the advantage of this reflex?

It increases the available oxygen to the bloodstream.

Explanation:

One of the primary functions of the circulatory system is the delivery of oxygen to the cells. Decreased blood pressure means that less blood is flowing through the system, thus decreasing the amount of delivered oxygen.

By increasing the amount of oxygen that can be adsorbed and transported by the bloodstream, the respiratory system response attempts to mitigate the decrease in volumetric delivery rate by an increase in transported oxygen concentration.
