Web20 mrt. 2024 · However, not every individual’s arterial PCO2 and respiratory exchange ratio are “normal” and differences can either increase or decrease the alveolar PO2. For example, an elevated PaCO2 decreases PAO2 while a reduced PaCO2 increases PAO2. The respiratory exchange ratio is affected both by diet and activity. WebThe amount of pressure exerted by carbon dioxide dissolved in the blood is known as the partial pressure of carbon dioxide, or pCO2, according to Eastern Kentucky University.
