1

CARBON DIOXIDE IS

- 24 x soluble in blood than oxygen
- 5% of total CO2 is carried in dissolved form in plasma (PaCO2)
- 5% of total CO2 is attached to carbamino compounds
- 90% IS CONVERTED TO BICARBONATE (HCO3) through carbonic anhydrase

2

carbon dioxide is transported in plasma through

- HCO3
- by the process of CHLORIDE SHIFT

3

chloride shift

- CHLORINE influx into the cell to create balance due to HCO3 efflux the cell in exchange
- HYPOCHLORINEMIA impaired transport of HCO3 shift to LEFT causing acidosis
