Frequently Asked Questions

What Is a Pulse Oximeter?

Pulse oximeters measure light absorption in the finger to noninvasively monitor oxygen saturation and pulse rate. Fingertip pulse oximeters are being increasingly used for general wellness and health applications including sports, fitness, and relaxation management.

Developed by Masimo, the leading brand of hospital pulse oximeters¹, the MightySat fingertip pulse oximeter provides accurate blood oxygen saturation and pulse rate measurements when other pulse oximeters fail.

Why should I buy MightySat over other Fingertip Pulse Oximeters?

Multiple companies have introduced low-priced, battery-powered “fingertip” pulse oximeters to the consumer market. In some circumstances, these products may provide inaccurate measurements or no measurements at all. This often occurs when there is low blood flow to the finger (such as when the fingers are cold) or during hand movement (even with minimal motion such as shaking). In addition, many of the products on the market are of low quality and do not interface with smartphones to store, manage, and share data.

What technology is behind the MightySat and iSpO2®?

Masimo Corporation originally developed Signal Extraction pulse oximetry for clinical use but now it is available for general wellness and health applications including sports, fitness, and relaxation management. Masimo Signal Extraction Technology (SET®) uses five parallel signal processing engines that measure through challenging conditions, including movement and low blood flow.

How can I use the information MightySat and iSpO2® provide me?

MightySat and iSpO2® provide data that athletes can monitor for better training, increasing or decreasing intensity, and monitor recovery to improve athletic performance.

* 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.
