Clinical Evidence

Masimo is passionate about making innovative technologies that give clinicians the tools they need to do what is best for patient care. That's why it is gratifying to see so many independent clinicians and clinical researchers take the time to independently evaluate our products and technologies—and then to communicate the positive impacts on patient care and safety that can be realized through their use.

More than 200 independent and objective studies by researchers around the world have demonstrated the clinical advantages of our technologies.
