WebAbstract. In normal subjects, exercise widens the alveolar-arterial PO2 difference (P [A-a]O2) despite a more uniform topographic distribution of ventilation-perfusion (VA/Q) ratios. While part of the increase in P (A-a)O2 (especially during heavy exercise) is due to diffusion limitation, a considerable amount is caused by an increase in VA/Q ... WebPCO2 will increase in blood. It also gets progressively harder as the respiration effort itself consumes O2 and produces CO2 and the pleural efffusion goes inside the alveoli and makes even more dead space. So an invasive ventilation could help mitigate the effort.

WebSep 26, 2024 · 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.
