The effect of mean arterial blood pressure (MAP) and arterial pH on the accuracy of pulse oximetry (SaO2-SpO2) is examined.A cohort consisting of 94 patients who were deemed by their treating physician to require an arterial blood gas sample had simultaneous SpO2 readings using 3 pulse oximeters (TempIR-Oxy, Jumper JPD-500A and Nonin Vantage 9590). Data were analysed using Pearson correlation co-efficient (r) and Bland Altman bias plot.Good correlation (r > 0.8) was observed for each of the finger pulse oximeters studied. The mean difference in measured oxygen saturation (bias) ranged from -2.9% to 0.2%. The standard deviation of differences was 1.9% to 3.0%. Fair agreement was demonstrated for the TempIR-Oxy and Jumper JPD-500A pulse oximeters with wide limits of agreement ranging from -8.9% to 2.9% and -6.7% to 3.4% respectively. The Nonin oximeter performed better with limits of agreements of -3.5% to 3.9%. The accuracy of pulse oximeter readings correlated poorly with both MAP and arterial pH.In conclusion, new commercially available finger pulse oximeters correlate well with SaO2, however agreement may vary from device to device.FootnotesCite this article as: European Respiratory Journal 2018 52: Suppl. 62, PA4452.This is an ERS International Congress abstract.
