The rate of breathing is primarily controlled by the level of carbon dioxide in the body. While levels of oxygen can also play a role, the body's respiratory centers are more sensitive to changes in carbon dioxide levels. When carbon dioxide levels rise, it triggers an increase in breathing rate to expel the excess CO2 and regulate pH levels in the blood.
