Increase in alveolar pco2

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 ...

WebPathology [ edit] The partial pressure of carbon dioxide, along with the pH, can be used to differentiate between metabolic acidosis, metabolic alkalosis, respiratory acidosis, and respiratory alkalosis . Hypoventilation exists when the ratio of carbon dioxide production to alveolar ventilation increases above normal values – greater than 45mmHg. 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. Together with morphine and furosemide.
