Masimo Signal Extraction Technology (SET) is a breakthrough technology that represents a new and fundamentally distinct method of acquiring, processing and reporting arterial oxygen saturation and pulse rate. Masimo SET greatly enhances the accuracy of SpO2 monitoring, particularly in the most difficult patient conditions such as motion and low peripheral perfusion. Masimo was also instrumental in launching FireRehab.com, the site dedicated to educating firefighters about the vital importance of rehabilitation in staying safe and healthy on the job.
