Answer :

Under typical physiological circumstances, an increase in PCO2 results in a drop in pH, which causes minute ventilation to increase and, as a result, alveolar ventilation to increase to achieve equilibrium. The amount of exchange and loss of PCO2 will increase in direct proportion to the minute ventilation.

What effect does CO2 have on ventilation?

The increase in respiratory frequency caused by the addition of CO(2) at these concentrations to the inspired oxygen was highest during the first breath and continued throughout the exposure time of one minute. A shorter expiratory time was the cause of the increase in respiratory frequency.

What occurs when the rate of minute ventilation is raised?

The only natural way for our bodies to quickly improve oxygenation is via raising the ventilation rate, as stated by the alveolar gas equation. We speed up and deepen our breathing, which lowers the partial pressure of CO2 and raises the alveolar oxygen tension.
