title: A comparison of oxygen saturation measurements obtained from a 'blue sensor' with a standard sensor.
abstract: OBJECTIVE
  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. SpO₂ measurements were recorded simultaneously from each sensor for 10 min. Agreement between pairs of SpO₂ measurements were calculated using Bland-Altman analysis.
  
  
  RESULTS
  Thirty-one infants were studied. There was good correlation between simultaneous SpO₂ measurements from both sensors (r² = 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.
  
  
  CONCLUSIONS
  The mean difference between the blue and standard sensor SpO₂ measurements is not clinically important.
