Masimo MightySat™ Fingertip Pulse Oximeter

From Openwaterpedia
SpO2, PR, RRp™, PVi® and PI can be measured on the Masimo MightySat™ Fingertip Pulse Oximeter

Masimo MightySat™ Fingertip Pulse Oximeter is a Bluetooth-enabled pulse oximeter that uses Signal Extraction Technology (SET®) for providing accurate physiological measurements.

Measurements

Masimo MightySat™ Fingertip Pulse Oximeter provides five parameters from noninvasive monitoring. For athletes, these parameters are key in objectively understanding how fit you are or are becoming. The Masimo pulse oximeter measures light absorption at the end of a fingertip in order to give users the following data points in real-time:

1. SpO2 or Oxygen Saturation is the oxygen level in the blood that indicates changes due to the heart or lung function, oxygen use by the 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 heart pulses per minute that indicates the 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 the heart and lungs function or how quickly an athlete recovers 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 the breathing cycle, which may indicate changes in hydration, breathing effort, perfusion, or other factors. The Plethsymographic Waveform displays the real-time pulse pressure waveform. To properly measure the PVi®, lay down relaxed in a horizontal position and take it at the same time of the day.

5. PI or Perfusion Index is the strength of the blood flow to the 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.
