Aim: The study aims to investigate pulse oximetry measurements from a 'blue' pulse oximeter sensor against measurements from a 'standard' pulse oximeter sensor in newly born infants.
Methods: Immediately after birth, both sensors were attached to the infant, one to each foot. SpO(2) measurements were recorded simultaneously from each sensor for 10 min. Agreement between pairs of SpO(2) measurements were calculated using Bland-Altman analysis.
Results: Thirty-one infants were studied. There was good correlation between simultaneous SpO(2) measurements from both sensors (r(2) = 0.75). However, the mean difference between 'blue' and 'standard' sensors was -1.6%, with wide 95% limits of agreement +18.4 to -21.6%. The range of mean difference between sensors from each infant ranged from -20 to +20.
Conclusion: The mean difference between the blue and standard sensor SpO(2) measurements is not clinically important.
