The solubility of oxygen in physiological salines

The oxygen solubility coefficient (O₂) of several different physiological saline solutions was measured over a broad range of temperatures (0 to 25C). Distilled water had a higher value than a physiological salt solution (similar to Cortland's saline). Plasma expanders (polyvinylpyrrolidone, dextran, albumin) lowered the O₂ value of the physiological salt solution. A salt solution with a 4% (w/v) mixture of protein substitute had a lower O₂ value than the corresponding 1% mixture. The solubility of oxygen was inversely related to temperature.
