The Masimo MightySat™ Rx Fingertip Pulse Oximeter incorporates Masimo SET® Measure-through Motion and Low Perfusion™ Pulse Oximetry, addressing issues related to low perfusion and motion artifacts that often constrain traditional pulse oximeters. This technology, known as Signal Extraction Technology® (SET®), employs five parallel signal processing engines to effectively monitor oxygen saturation and pulse rate, even in challenging situations, such as during motion or when blood flow is limited.


  • High Resolution Display – Rotating and adjustable color screen for real-time display of all measurements
  • Plethysmographic Waveform – Provides high-resolution display of the patient’s pleth waveform
  • Touchpad – Provides easy access to settings and device features
  • Durable, Lightweight Design – For use in clinical and home-care environments
  • Signal I.Q.® (SIQ™) – An indicator of the SpO2measurement confidence
  • Flexible Pad – Easily conforms to finger shape for enhanced comfort, enables secure application to finger to minimize external interference
  • Kit includes: MightySat Rx device, lanyard, batteries, and drawstring pouch
  • Free Downloadable Masimo Professional Health App – Display parameter data on compatible smart devices with Bluetooth LE-enabled models. (Measurements can also integrate into Apple’s Health app.)


  • Signal IQ® (SIQ) Located under the plethysmographic waveform. The height of the vertical line provides an assessment of the confidence in the SpO2 value displayed.
  • Plethysmographic (Pleth) Waveform
  • Real-time graphical representation of changes in volume of arterial blood with each pulse.
  • Perfusion Index (Pi)
  • A measure of the dynamic changes in the perfusion index (Pi) that occur during the respiratory cycle.
  • Pleth Variability Index (PVi)
  • The ratio of the pulsatile blood flow to the non-pulsatile blood in peripheral tissue used to measure peripheral perfusion.
  • Respiration Rate from the Pleth (RRp)
  • A measure of respiration rate based on changes in the plethysmographic waveform. The unit of measure is respiration per minute (RPM).
