Abstract

A nomogram was constructed which allows estimation of the P50 value from the Po2 and per cent O2 saturation of a single venous blood sample. There was excellent correlation between 50 estimated P50 values obtained in 27 severely ill patients when compared with P50 values determined from constructed OH-DC's (correlation coefficient 0.92). The mean of the differences between the estimated and determined P50 values was 1.5 mm Hg with a standard deviation of ±1.1, and the maximum difference was 4 mm Hg.
