The KAATSU Master 2.0 and KAATSU Wearables both use the Masimo MightySat™ Finger Pulse Oximeter.

One of the best physiological monitoring devices that I have ever used is the Bluetooth-enabled Masimo MightySat™ Fingertip Pulse Oximeter,” said Steven Munatones.

I can simultaneously track and archive the oxygen level in my blood, my pulse, the number of breaths per minute, a measure to understand how well hydrated that I am, and other data points that indicate changes in blood circulation and heart rate recovery. We use the Masimo with the athletes – of all ages – who we work with.”

The six specific parameters that can be tracked noninvasively include the following data points:

1. SpO2 or Oxygen Saturation is the oxygen level in your blood that indicates changes due to your heart or lung function, oxygen use by your body, or altitude. It is a percentage of hemoglobin in the blood that is saturated with oxygen. The unit of measure is percentage (%).

2. PR or Pulse Rate is the number of your heart pulses per minute that indicates your overall fitness or exertion levels at any time. The unit of measure is beats per minute (bpm).

3. RRp™ or Respiration Rate is the number of breaths per minute that indicates how well your heart and lungs function or how quickly you recover from exercise. It is a measurement of respiration rate based on changes in the plethysmographic waveform. The unit of measure is respirations per minute (RPM).

4. PVi® or Plethysmograph Variability Index is the variation in perfusion index over your breathing cycle, which may indicate changes in hydration, breathing effort, perfusion, or other factors. The Plethsymographic Waveform displays your real-time pulse pressure waveform. To properly measure your PVi®, you should lay down relaxed in a horizontal position and take it at the same time of the day in the same position.

5. PI or Perfusion Index is the strength of your blood flow to your finger that indicates changes in blood circulation. It is the ratio of the pulsatile blood flow to the non-pulsatile blood in peripheral tissue used to measure peripheral perfusion. The Perfusion Index values ranges from 0.02% for a very weak pulse to 20% for an extremely strong pulse.

6. The Heart Rate Recovery Calculator can track the heart’s ability to return to normal levels after vigorous physical activity or hard swimming set. Fitness level and proper heart function are measured by the recovery phase. A heart that is fit will recover at a quicker rate than a heart that is not accustomed to regular exercise. The first minute of recovery is the most crucial. After exercise, your heart rate experiences an abrupt drop during the first minute. This recovery period can indicate cardiovascular fitness level.

The Masimo’s Heart Rate Recovery Calculator is used by putting on the MightySat on your finger right after exercise and opening the Masimo mobile app. After 60 seconds, you will receive your percentage score.

As a general rule, a lower recovery heart rate following vigorous exercise is better.
