Comparison of bias at 30 min among four sensor locations. The absolute values of bias obtained via forearm (n = 143) and chest (n = 129) sensors were equivalent, and were significantly lower than those obtained via the earlobe (n = 17) or forehead (n = 6) sensors for both PCO2 and PO2. The absolute values of PO2 bias obtained via the earlobe sensor were significantly lower than those obtained via the forehead. ANOVA with Tukey’s pot-hoc test, *: P < 0.05, **: P < 0.01, Bars: SEM
