Decreased solubility decreases gas exchange. Solubility for a given gas is constant, and solubility is grouped with gas molecular weight as the diffusion constant. Solubility is an important consideration for O 2 exchange, since O 2 is much less soluble than CO 2. Finally, CO is highly soluble and is not normally present in the blood, allowing clinical use of CO to estimate lung-diffusing.
