Proven Accuracy Compared to Laboratory Devices1

  • > In Masimo’s FDA submission, SpHb was validated in a range of 8 to 17 g/dL with accuracy of
    1.0 g/dL ± at one standard deviation.2
  • > An independent study in the surgical intensive care unit evaluated 471 haemoglobin measurements from 62 patients. SpHb, a satellite laboratory CO-Oximeter (Siemens RapidPoint 405), and a point-of-care device (HemoCue 301) were compared to reference haemoglobin from the central laboratory hematology analyser (Sysmex XT2000i).
  • > The bias ± precision of each method was as follows:
> SpHb 0.0 ± 1.0 g/dL
> CO-Oximeter 0.9 ± 0.6 g/dL
> Point-of-care device 0.3 ± 1.3 g/dL
  • > In the same study, changes in SpHb compared to changes in the reference haemoglobin showed the same correlation as the laboratory CO-Oximeter and better correlation than the point-of-care device.1

SpHb is Proven to Help Clinicians Reduce Blood Transfusions during Surgery3

  • > In a randomised controlled trial in orthopedic surgery at a major U.S. teaching hospital, clinicians using SpHb transfused their patients 87% less often than clinicians not using SpHb (0.6% vs. 4.5%).

SpHb Measurements During Liver Transplant Surgery

In this research case, SpHb values were blinded to the clinicians so that the frequency of lab measurements was unaffected.
