Masimo MightySat® Finger Pulse Oximeter

Hospital-grade pulse oximeter to capture your pulse rate, oxygen saturation, perfusion index, and respiratory rate.

The optional Masimo MightySat® Finger Pulse Oximeter is a hospital-grade technology that measures and monitors the following data during exercise or rehabilitation:

  • Pulse Rate (PR) or the number of heart pulses per minute indicates your overall fitness and exertion levels.
  • Oxygen Saturation (SpO2) or the oxygen level in the blood indicates changes due to your heart or lung function, oxygen use by your body, and altitude.
  • Perfusion Index (PI) indicates the strength of blood flow to the finger as blood circulation changes.
  • Respiration Rate (RRp) or the number of breaths per minute indicates how well your heart and lungs are functioning and how quickly you recover from exercise.
  • Pleth Variability Index (PVi) or the variation in perfusion index over your breathing cycle which may indicate changes in hydration, breathing effort, perfusion or other factors.
  • Hospital-grade technology captures oxygen saturation, pulse rate, perfusion index and respiration rate.

The Masimo MightySat® Finger Pulse Oximeter integrates with the KAATSU B2, B1, and M3 models via Bluetooth.
