Carbon dioxide
Carbon dioxide
CO2 content is hard to calculate because of the 3 forms of carriage:
- Dissolved (5%)
- Bicarbonate (90%)
- Carbamino compound (5%)
Contribution to a-v difference of CO2 content
- Dissolved - 10%
- Bicarbonate - 60%
- Carbamino - 30%
NB:
According to KB,
- PaCO2 = 40mmHg
- PvCO2 = 46mmHg
Thus,
- CvCO2 = 48mL of CO2/dL
- CvCO2 = 52mL of CO2/dL
