Q. How does the pulmonary ventilation affect the carbon dioxide concentration in blood? What happens to the carbon dioxide concentration and to the blood pH when the respiratory frequency is either lowered or increased?
The pulmonary ventilation frequency number of inhalations per time unit lowers or raises the carbon dioxide concentration in blood, if it is intense the gas is more eliminated to the exterior and if it is reduced the gas is retained inside the organism.
Applying the principles of chemical equilibriums to the formation of bicarbonate from water and carbon dioxide one gets the following: if the carbon dioxide concentration is increased the equilibrium shifts towards the liberation of hydrogen ions and formation of bicarbonate and the pH of the solution is lowered; if the carbon dioxide concentration is lowered the equilibrium shifts reversely towards the formation carbon dioxide and of water and also of more hydrogen ions spending and the pH of the solution is raised.
