SpHb Analytical Performance

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

  • 0.08 g/dL bias
  • 0.96 g/dL ARMS accuracy
  • 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

*Masimo FDA Submission Data (Accuracy of Noninvasive Total Haemoglobin (SpHb) Measurement with Pulse CO-Oximetry). The study was performed in compliance with the requirements of IS09919:(2005) Standard.

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.

Prior to using this device, the user should read and understand the Operator’s Manual and Directions for Use. Laboratory diagnostic tests using blood samples should be conducted prior to clinical decision making to completely understand the patient’s condition. Comparisons between SpHb measurements and laboratory diagnostic hemoglobin measurements may be affected by sample type, collection technique, physiological, and other factors
