SpHb Analytical Performance

chart comparing SpHb from Masimo Pronto-7 versus invasive tHb measurements from a laboratory reference device

In 492 comparisons of SpHb and invasive hemoglobin (tHb) measurements from a laboratory CO-Oximeter, SpHb accuracy was as follows1:

  • 0.08 g/dL bias
  • 0.96 g/dL at one standard deviation
  • Below 12 g/dL, 99% of SpHb readings were <2 g/dL of the laboratory tHb value
  • At or above 12 g/dL, 94% of SpHb readings were <2 g/dL of the laboratory tHb value

Please note: These results were obtained following a specific protocol, in which all Directions for Use were followed and SpHb measurements were compared to validated laboratory reference measurements. Differences in results may be caused by many factors, such as those explained in Masimo’s Directions for Use. Some independent researchers have conducted their own testing and obtained similar results, while other researchers have reported larger differences when comparing SpHb measurements to laboratory measurements.
