In 60 neonates (gestational age, 26.5–40 weeks; postnatal age, 1–14 days) and in 11 infants (gestational age, 26–33 weeks; postnatal age, 4.5–38 weeks), the accuracy of two wavelength pulse oximetry was examined. A total of 112 comparisons between transcutaneous pulse oximetry saturation (StcO 2 , NELLCOR™ N‐100) and arterial oxygen saturation (SaO 2 , OSM2 RADIOMETER™) were obtained. SaO 2 ranged from 80 to 100%. Criteria for comparison between StcO 2 and SaO 2 were standardized: patients in behavioral state 1, StcO 2 stable for 2 min, and arterial samples drawn from an indwelling arterial line. StcO 2 was significantly related to SaO 2 ( P < 0.01), but the difference, StcO 2 ‐ SaO 2 , significantly increased when SaO 2 decreased [StcO 2 ‐ SaO 2 (%) = ‐0.39 SaO 2 (%) + 37.95; r = ‐0.64, P <0.01]. No significant relationship was found between StcO 2 ‐ SaO 2 and either bilirubinemia (range, 5–222 m̈mol/L) or fetal hemoglobin (HbF) (range, 12–95%). We conclude that StcO 2 overestimates SaO 2 when SaO 2 decreases, and this overestimation is not due to high levels of bilirubin or HbF.
