MightySat™ Rx Fingertip Pulse Oximeter from Masimo features Masimo SET® Measure-through Motion and Low Perfusion™ Pulse Oximetry which overcomes the challenges of low perfusion and motion artifact that limit conventional pulse oximetry. This Signal Extraction Technology® (SET®) uses five parallel signal processing engines that measure through challenging conditions allowing users to accurately measure oxygen saturation and pulse rate even during movement or low blood flow. The MightySat also provides unique measurements that help to assess changes in breathing rate, breathing effort, hydration, or other factors. In addition, the free downloadable Masimo Personal Health app allows users to do more with their data for easy trending, sharing, and integration on a compatible smart device (Bluetooth models only).

The MightySat Rx delivers consistently accurate measurements for:

  • Oxygen Saturation (SpO2) Oxygen level in the blood to indicate changes due to heart or lung function, oxygen use by your body, or altitude
  • Pulse Rate (PR) Number of heart pulses per minute to indicate overall fitness or exertion levels at any time
  • Perfusion Index (Pi) Strength of blood flow to the finger to indicate changes in blood circulation

Additionally, the MightySat Bluetooth models offer a more complete picture than the limited data available from other health and wellness devices:

  • Respiration Rate (RRp) Number of breaths per minute to indicate how well your heart and lungs are functioning or how quickly you recover after exercise
  • Pleth Variability Index (PVi) Variation in perfusion index over your breathing cycle, which may indicate changes in hydration, breathing effort, perfusion, or other factors
