Webto the amplitude of oscillations of Pc02 in arterial blood could provide a sufficient stimulus to ventilation to prevent a rise in mean PCO~ during exercise. In 1964, Dutton et al.20, found that cyclic variation of the inspired Pc02 of anaesthetised dogs produced an increase in ventilation above that due to the average increasein Pco~. WebpH is an index of acidity or alkalinity of the blood, which in normal arterial blood is between 7.35 to 7.45. Patients with pH lower than 7.35 are in acidosis, while those with a pH higher than 7.45 are in alkalosis. pCO2 is a measure of the partial pressure of carbon dioxide dissolved in blood; since its levels vary based on ventilation, it also represents the …
