Noble-gas partition coefficients between whole blood and air as determined in this study for two subjects (S1 and S2) compared with values from the relevant literature.

The partition coefficients are expressed as nondimensional ratios of the gas concentration in blood (in cm3STP of gas per cm3 of whole blood, assuming a whole blood density of 1.06 g/cm3, where 1 cm3STP = 22414−1 Mol) to the corresponding volume fraction of the gas in dry air (in vol/vol). aBased on the linear relationship between hematocrit and partition coefficient in [23]. bCalculated using a linear relationship between the partition coefficients of red blood cells (40%) and plasma (60%). cCoefficients as calculated in [22]. dErrors represent the standard deviations of the original measurements.
