What Better Data Means to You

MightySat is ideal for people who know they want a fingertip pulse oximeter and want the best available technology. MightySat is also for people who want to improve their health, wellness, or fitness by providing key measurements that are more accurate and not available on other health and wellness devices.

Accurate When You Need it Most

The Leading Hospital-Grade Technology
Masimo pulse oximeters are the leading brand in hospitals because of Signal Extraction Technology (SET®), which provides accurate measurements when other hospital-grade pulse oximeters fail—during movement and low blood flow.
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 on MightySat

MightySat gives you 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 * 1 2 3

* 10 volunteers with adhesive finger sensors from Masimo and the #2 hospital-grade brand were tested during movement and low blood flow with machine- and volunteer-generated hand motions to calculate accuracy, which was defined as oxygen saturation within 7% and pulse rate within 10% of reference.
** It is suggested to measure PVi in the same body position, remaining still and without talking, at the same breathing rate and depth of breathing, until you see a high confidence PVi value (displayed value is bright, not dim). An increase in PVi may indicate a decreased level of hydration, increased breathing effort, or other factors. A decrease in PVi may indicate an increased level of hydration, decreased breathing effort, or other factors. Multiple factors other than hydration and breathing effort can affect PVi, including breathing rate, depth of breathing, body position, body movement, vascular tone, blood flow to the finger (perfusion index), normal variation within a short-term monitoring session, waveform shape changes, and/or cardiovascular abnormalities.
