OBJECTIVE: To investigate pulse oximetry in neonates who require arterial access as represented by the clinical data recorded to manage their care. STUDY DESIGN: Analysis of simultaneous SpO[SUB2] and SaO[SUB2] (from: 7-year historical NICU) data (N =31,905); 4-month prospective NICU data (N =566); verification data using two hemoximeters (N =52); and NICU data from two collaborating centers (N =95 and 168). The bias function SpO[SUB2]-SaO[SUB2] was regressed against the measured ''gold'' standard, SaO[SUB2]. RESULTS: A significant negative correlation was found for each of the data sets (between the bias function and SaO[SUB2]. This bias was similar for devices from several manufacturers (Datex-Ohmeda, Masimo, Nellcor, and Spacelabs). Maximum operational performance occurred with peaks between 92 and 97% SaO[SUB2], but declined markedly above and below this narrow range. In all, 71 to 95% of patients exhibited data with significant bias. CONCLUSION: These operational data suggest that with the methodology and devices currently in use, SpO[SUB2] values in most all neonates who require arterial lines inaccurately correlate with measured arterial saturation.
