The MightySat® Fingertip Pulse Oximeter measures:
Oxygen level in the blood to indicate changes due to heart or lung, oxygen use by your body, or altitude
Number of heart pulses per minute to indicate overall fitness or exertion levels at any time
Strength of blood flow to the finger to indicate changes in blood circulation.
Number of breaths per minute to indicate how well your heart and lungs are functioning or how quickly you recover after exercise
Variation in perfusion index over your breathing cycle, which may indicate changes in hydration, breathing effort, perfusion, or other factors * 1 2 3
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.

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

*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.
**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.
