Detailed explanation-1: -Carbon dioxide influences the pH of blood by reacting with water to form carbonic acid (H2CO3), which can dissociate to form a hydrogen ion (H+) and a hydrogen carbonate ion (HCO3-). Increasing the concentration of carbon dioxide in the blood therefore results in more H+ ions and a lower pH.
Detailed explanation-2: -The partial pressure of carbon dioxide (PCO2) is the measure of carbon dioxide within arterial or venous blood. It often serves as a marker of sufficient alveolar ventilation within the lungs. Generally, under normal physiologic conditions, the value of PCO2 ranges between 35 to 45 mmHg, or 4.7 to 6.0 kPa.
Detailed explanation-3: -For an acute change in pCO2 of 10, the pH will change by 0.08. If all changes in pH can be accounted for by the change in pCO2, then the problem is an acute respiratory acidosis or alkalosis. If not, there is a metabolic component.
