SpHb Analytical Performance

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

In 11,335 comparisons of SpHb and invasive haemoglobin (tHb) measurements from a laboratory reference device, SpHb accuracy was as follows:*

  • -0.02 g/dL bias
  • 0.99 g/dL ARMS accuracy
  • Between 6 - 12 g/dL, greater than 95% of SpHb readings were within 2 g/dL of the laboratory tHb value
  • Between 12 - 18 g/dL, greater than 95% of SpHb readings were within 2 g/dL of the laboratory value

*Masimo FDA 510(k) Submission Data using normal sensitivity mode.

Please note: These results were obtained in normal sensitivity mode 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.

For professional use. See instructions for use for full prescribing information, including indications, contraindications, warnings, precautions and adverse events.
