Masimo provides this step-by-step user guide to assist you in the use of the MightySat device:

Setup

  • Download the free Masimo Personal Health App on the App Store or Google Play
  • Follow the App instructions to sync your MightySat with your smart device

Listen to your body by quickly and accurately measuring key physiologic variables

  • Place the MightySat on your ring finger and wait for the numbers to appear on the display
  • Tap the square below the screen to rotate the display for your optimal viewing angle

Take note of your measurements:

Oxygen Saturation (SpO2)

A measure of the oxygen saturation level in your arteries. Higher oxygen saturation indicates more oxygen in the arterial blood. Oxygen saturation can change due to a number of factors, including lung or heart function and altitude.

Pulse Rate (PR)

The number of time your heart pulses, or beats, per minute. This parameter is useful for assessing overall fitness as well as exertion levels at a particular moment in time.

Perfusion Index (Pi)

Pi is the ratio of the pulsing blood to non-pulsing blood flow in your finger and is used to indicate the strength of blood flow to your finger.

Monitoring your body

Learn from your body by monitoring yourself in the morning, after exercise, or anytime you want to know what your body is telling you

Morning Monitoring

  • Keep your MightySat at your bedside and each morning
  • Monitor yourself before you get out of bed
  • Establish your normal, or "baseline" values

Oxygen Saturation (SpO2)

A fully oxygenated body generally means a fully recovered and ready body. An SpO2 between 97 and 100% means your body is ready!

Note: At higher elevation starting at about 3,000 feet, it is normal for your SpO2 to be 3 to 5% lower. The higher elevation you go, the lower your SpO2 will be.

Pulse Rate (PR)

Your pulse rate changes constantly to provide the necessary blood flow to deliver the oxygen your body needs. Generally, a lower resting pulse rate (40 to 60 beats per minute) means your body is performing more effectively and efficiently.

Perfusion Index (Pi)

Your perfusion index changes based on whether the blood flow to your body is going up or down, and whether the arteries in your fingers are narrowing (causing your fingers to feel colder) or widening (causing your fingers to feel warmer). There is no specific “normal” value for perfusion index, each person should establish their own baseline value and note how it changes over time. A higher perfusion index means greater blood flow to the finger and a lower perfusion index means lower blood flow to the finger. Your perfusion index may or may not change significantly in the morning or after exercise. Note any changes to your perfusion index and whether you feel any differently when your perfusion index is lower.

After exercise monitoring

  • Keep your MightySat at your bedside and each morning
  • Monitor yourself before you get out of bed
  • Establish your normal, or "baseline" values

Oxygen Saturation (SpO2)

A fully oxygenated body generally means Measure how long it takes for your oxygen saturation to return to your baseline value (example, from 95% to 98%).

Pulse Rate (PR)

Measure how long it takes for your pulse rate to go down by 20 beats per minute (example, from 160 to 140 beats per minute).

Live at your best by tracking and trending your data to make adjustments in exercise, diet, or rest/relaxation

Morning monitoring

Oxygen Saturation (SpO2)

If your oxygen saturation drops more than 3% from baseline, or if it is below 96%, this may be an indication that you need more rest and recovery.

Pulse Rate (PR)

If your resting pulse rate is 10 beats per minute higher than normal, this may be an indication that you are dehydrated, stressed, or fatigued. This may be an indication that you need to rehydrate, relax, or skip intense workouts.

After exercise monitoring

Oxygen Saturation (SpO2)

If your oxygen saturation takes longer to return to your baseline value, this may be an indication that you need more rest and recovery.

Pulse Rate (PR)

If your pulse rate takes longer than usual to fall by 20 beats per minute, this may be an indication that you need:

 

  • To rehydrate
  • Give yourself more rest and recovery
  • Change your workout regimen, as you may have hit a plateau and may need a different type of workout to make progress (example, if you have been doing all aerobic training at moderate pulse rate levels, you may need to consider more interval training at higher pulse rate levels to improve your recovery time).

FAQs

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.

Is there a pediatric probe attachment for this product?

No. The MightySat® is intended for spot-checking on people above the weight 30kg/ 66lbs.

Does the Masimo Personal Health App sync with Apple Health?

Yes, it does. You have to authorize it in the settings for both Apps.

How do I connect my MightySat® and iSpO2® MightySat® device to my smartphone?

Parameter data can be displayed on a compatible smart device with Bluetooth® LE models. Bluetooth® LE is an optional feature available on specific versions of MightySat® for use with compatible smart devices. For a full list of compatible smart devices, see masimopersonalhealth.com/products/mightysat . The free Masimo Personal Health App is downloadable from the Apple App Store for iOS devices or Google Play™ store for select Android devices. Please note that a MightySat® is required for the App to work.

Does MightySat® work with iOS 9, 10, 11, 12, and 13?

Yes, the MightySat® does work with iOS 9, 10, 11, 12, and 13.

Does it work with iPhone 6?

If your iPhone has Bluetooth® capability and you purchase a MightySat® with Bluetooth®, then, yes, it will work with the iPhone 6.

Does MightySat® work on Android Phones?

Yes, MightySat® Models 9800 and 9900 are compatible with Android Jelly Bean, KitKat, Lollipop, and Marshmallow.

* 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.
