“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 another data point that indicates changes in blood circulation. We use the Masimo with the athletes who we work with.”
The five 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 (%).
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 is the percentage of your ability to recover within 60 seconds of stopping aerobic activities. So if you hit 160 beats per minute and then stop, the Heart Rate Recovery will measure how much as a percentage your heart rate falls after 60 seconds. So if your pulse rate falls to 80 after 60 seconds, the Heart Rate Recovery gives you this information.
