  • More than 100 independent and objective studies demonstrate Masimo SET provides the most reliable SpO2 and pulse rate measurements even under the most challenging clinical conditions, including patient motion and low peripheral perfusion.
  • Masimo Rainbow® SET technology analyzes multiple wavelengths of light to accurately measure total hemoglobin (SpHb), oxygen content (SpOC®), carboxyhemoglobin (SpCO), methemoglobin (SpMet®), and PVI® noninvasive and continuously.

Clinical Benefits:

  • Masimo SET pulse oximetry - Virtually eliminates false alarms without missing true clinical events.
  • Upgradable Rainbow SET Pulse CO-Oximetry measurements include:
    • Total Hemoglobin (SpHb) *
    • Oxygen Content (SpOC)
    • Carboxyhemoglobin (SpCO)
    • Methemoglobin (SpMet)
    • PVI
  • A: SIQ bar provides continuous indication of signal quality levels.
  • B: Pressing the display button allows user to toggle between parameters loaded on device.
  • C: The Alarm Status Indicator flashes when an alarm condition is present.
  • D: PI bar provides continuous indication of perfusion index.
