Figure 4. Dissolved oxygen gas (O2) properties of aCSF at the site of tissue perfusion using the in-bore oxygenator with gases of variable oxygen content.
Three mixtures of carbogen gas (5% CO2 + 95%, 60%, 19% O2 balance N2) are compared to an aCSF reservoir exposed to atmospheric gas (20–22% O2; 23% measured) and positive control (directly bubbled 95% O2, 5% CO2 carbogen). In all three instances, measured dissolved oxygen content in the aCSF approaches 100% saturation of the concentration contained within the supplied gas mixture. Data is presented as group averages (n = 6) with positive error bars equal to the calculated standard deviation.
