The quotient of exhaled CO2 (VeCO2) and arterial CO2 (Ve/PaCO2) is a measure of the ventilatory response to hypoxia.
The difference between exhaled CO2 (VeCO2) and arterial CO2 (PaCO2-VeCO2) is a measure of physiologic dead space
VeCO2 and PaCO2
- VeCO2/PaCO2: measure of ventilatory response to hypoxia
- PaCO2 – VeCO2: measure of dead space
