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 hemoglobin 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 hemoglobin from the central laboratory hematology analyzer (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 hemoglobin 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 Surgery²

• > In a randomized 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%).
