Noninvasive and continuous hemoglobin (SpHb®) is a breakthrough measurement that allows clinicians to track hemoglobin changes in real time.


Technology Platform

rainbow® Pulse CO-Oximetry is a noninvasive monitoring platform enabling the assessment of multiple blood constituents which previously could only be measured invasively—in addition to Masimo SET® Measure-through Motion and Low PerfusionTM pulse oximetry.

Masimo Radical-7 upgraded with RRa

  • > Total Hemoglobin (SpHb®)
  • > Carboxyhemoglobin (SpCO®)
  • > Methemoglobin (SpMet®)
  • > Oxygen Content (SpOC)
  • > Acoustic Respiration Rate (RRa)
  • > Oxygen Saturation (SpO2)
  • > Pulse Rate (PR)
  • > Perfusion Index (PI)
  • > Pleth Variability Index (PVI®)

The upgradeable rainbow® platform lets you choose the rainbow® measurements that are right for you now and be confident that your investment in patient safety won’t become obsolete tomorrow.
