  • Overview

    Masimo's MightySat fingertip pulse oximeter uses the best hospital-grade technology to accurately measure your oxygen saturation and pulse rate when you need it most. MightySat also provides unique measurements that help you assess changes in breathing rate, breathing effort, hydration, or other factors. And the Masimo Personal Health app brings it all together for easy trending, sharing, and integration of your data with the Health app on your iPhone or iPad.

    Reliable accuracy

    MightySat delivers consistently precise readings of several essential measures: 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.

    Breakthrough measurements

    In addition to standard indicators, MightySat delivers some unique measures: 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.

    How to use MightySat

    Listen to your body by quickly and accurately measuring key variables in the morning, after exercise, or anytime you want to know what your body is telling you. Then over the long term you can understand even more by tracking and trending your data in the Masimo Personal Health app on your iOS devices. Using this knowledge, you can adjust your exercise, diet, rest, or relaxation to help live the best life possible.
