Data Monitoring

An optional Masimo MightySat™ Fingertrip Pulse Oximeter measures and monitors the following data during exercise or rehabilitation: 

  • Pulse Rate (PR) or the number of heart pulses per minute indicates your overall fitness and exertion levels
  • Oxygen Saturation (SpO2) or the oxygen level in the blood indicates changes due to your heart or lung function, oxygen use by your body, and altitude 
  • Perfusion Index (PI) indicates the strength of blood flow to the finger as blood circulation changes 
  • Respiration Rate (RRp) or the number of breaths per minute indicates how well your heart and lungs are functioning and how quickly you recover from exercise 
  • Pleth Variability Index (PVi) or the variation in perfusion index over your breathing cycle which may indicate changes in hydration, breathing effort, perfusion or other factors.

The KAATSU Master 2.0 also measures and archives additional information such as: 

  • KAATSU Time (KT) or the amount of time spent doing KAATSU per session
  • Capillary Refill Time (CRT) or the amount of time in seconds that it takes for your capillaries to refill with blood
  • KAATSU Exercise (KE) or the type of exercise, movement or rehabilitation you do with KAATSU
  • KAATSU Cycle Function (KCf) or the specific type of KAATSU Cycle (e.g., Cycle 20 or Customized Cycle)


  • Physical therapy offices
  • Chiropractors
  • University athletic departments & training rooms
  • Retirement communities
  • Competitive sports teams
  • Corporations

KAATSU Band Design

KAATSU the Original Blood Flow Restriction (BFR) is generically described by Japanese physicians as Blood Flow Modification due to a variety of factors including the specific design and engineering of the KAATSU Air Bands.

After 35 years of Research Kaatsu is the World Leader in Blood Flow Restriction Training and is the Only Original BFR device on the market that is following Dr. Sato’s 35 years Research for Safety.

  1. Stretchable Material for BFR

The Bands are designed to reduce venous flow (blood flow back to the torso).The Bands do not occlude arterial flow (blood flow to the limbs). This is very different from blood pressure cuffs that are specifically designed to occlude (cut off) blood flow to the limbs. 

  1. Patented BFR Width

The Width of the Bands is also much different than a blood pressure cuff (i.e., it avoids arterial flow occlusion). The Bands very importantly allows for ease of movement of the limbs (for walking, running, cycling, calisthenics, physical therapy, swimming, throwing, pulling, pushing or any specific movements required in sports or fitness).

  1. Unique BFR Function

The Bands include baffles and a stretchable air bladder that inflates uniformly and towards the limb, precisely controlled by the KAATSU monitoring units (e.g., KAATSU Master 2.0, KAATSU Nano, KAATSU Wearables).

  1. Maximum BFR Safety

The Bands can be immediately deflated by either pushing buttons on the monitoring units, depressing the value on the connectors, or releasing the Velcro on the Bands.

  1. Safe For All Ages

The Bands and the Devices are specifically designed and engineered to follow the 35 year research of Dr. Sato and the Japanese team.

Users of all ages can use it with maximum safety. The Patented Width, the Stretchable Material, 35 years of Research and the unique BFR function make it the safest BFR bands on the market without any risk of Occlusion (stop the blood flow).

Safety Has Always Been First and Foremost
