When there is a decrease in concentration of oxygen in blood, the breathing rate increases.
Actually speaking, rate of breathing doesn’t really depend on the concentration of oxygen in blood. It’s dependant on the CO2 and H+ concentration.
So when those increase, the pneumotaxic centre in pons signals the Respiratory rhythm centre in the medulla oblongata to increase the respiratory rate which increases oxygen in our blood and evicts CO2.
