MightySat Rx gives you a more complete picture of respiratory health

Accurate when you need it most

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)

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

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

Measurements only available with Masimo SET®

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

Over 100 Independent and Objective Studies have Shown that Masimo SET® Outperforms Other Pulse Oximetry Technologies.2

For more than 25 years, clinicians have trusted Masimo pulse oximetry to help improve patient outcomes. Before Masimo, pulse oximeters were often unreliable, providing inaccurate measurements and frequent false alarms. Masimo revolutionized the industry with the development of Signal Extraction Technology® (SET®).

SET® differentiates Masimo from other pulse oximetry technology by using advanced signal processing techniques to separate the arterial signal from sources of noise. This key advantage ensures that Masimo SET® delivers truly accurate measurements—even during challenging conditions.

Powered by Masimo SET®, MightySat Rx provides accurate measurements when other pulse oximeters fail:

  • During movement
  • Low blood flow/cold extremities
  • For any skin pigmentation
  • In brightly lit environments
