Shedding light on venoarterial PCO<sub>2</sub> gradient
As an expression on Fick’s principle, the reduction in cardiac output is associated with a parallel increase in both mixed venoarterial CO<sub>2</sub> content diference (C<sub>mv-a</sub>CO<sub>2</sub>) and arterial-mixed venous oxygen content diference (C<sub&g...

| Sumario: | As an expression on Fick’s principle, the reduction in cardiac output is associated with a parallel increase in both mixed venoarterial CO<sub>2</sub> content diference (C<sub>mv-a</sub>CO<sub>2</sub>) and arterial-mixed venous oxygen content diference (C<sub>a-mv</sub>O<sub>2</sub>). Nevertheless, disproportioned elevations in C<sub>mv-a</sub>CO<sub>2</sub> compared to those of C<sub>a-mv</sub>O<sub>2</sub> ensue when the anaerobic threshold is reached. Tis results from anaerobic CO<sub>2</sub> production, secondary to the bufering of anaerobically generated protons by bicarbonate. |
