A More Complete Picture

MightySat gives you a more complete picture of respiratory status than
the limited data available from other health and wellness devices.

Oxygen Level (SpO2)*
Oxygen levels in your blood can change with heart and lung function, activity, and altitude

Pulse Rate (PR)
How often the heart pushes blood through your body, which can change with general health, physical activity, and with your mental or emotional state (e.g., stress, anxiety)

Breaths per Minute (RRp®†)
The number of breaths you take in a minute, based on the pleth; respiration rate can change with your general health condition, physical activity, or mental or emotional state

Pleth Variability Index (PVi®)
A calculation based on the changes in your perfusion index, which may be affected by your fluid volume during your respiration cycle and can increase with lower fluid levels

Perfusion Index (Pi)
A calculation of the relative strength of your pulse, which changes based on your circulation
