title: Solubility of 92 in blood with different hemoglobin concentrations at low temperatures.
abstract: The Brunsen solubility coefficients for O2 in blood obtained from healthy nonsmoking subjects have been determined at 0, 6, and 12 degrees C for bloods of hemoglobin concentrations 5.6, 10.2, 15.7, and 22.5 g/100 ml. Direct gasometric measurements show that blood has a relative solubility (alphabeta/alphah2o) different for each hemoglobin concentration but constant for any given hemoglobin concentration at the temperatures studied (0.6, and 12 degrees C). For hemoglobin concentrations 5.6, 10.2, 15.7, and 22.5 g/100 ml alphabetao degrees C/alphabeta 12 degrees C rations were 1.36, 1.35, 1.35, and 1.35, respectively. The alpha H20(0 degrees C)/alpha H20(12 degrees C) ratio is 1.34. Consequently, it was possible to construct a table for the Brunsen solubility coefficients for O2 in blood from O to 15 degrees C of different hemoglobulin concentrations. Values from 10 to 15 degrees C published in the Biologal Hanbook, Respiration and Circulation, based on extrapolations from previous direct measurements of temperatures from 18 to 37 degrees C differ only 1% from our present results.
