Pulse oximeter bias function: other nicus. NICU "A" provided 95 paired SpO2 (Spacelabs) and SaO2 values. NICU "B" provided 168 paired values (Datex-Ohmeda 3740). The correlation coefficients for the pulse oximetry bias function for NICU "A" and "B" were: r=-0.92 (p<0.001) and r=-0.72 (p<0.001), respectively. At these sites as well, the pulse oximetry bias is seen to worsen as saturation values decrease.
