COVER STORY

Masimo Corp. may not have anticipated finding so much of it in the marketplace, but the company knows a little something about interference. Finding ways of dealing with it is the basis of the company's key technology.

Invented by company founders Joe E. Kiani and Mohamed Diab in 1989, Masimo's signal extraction technology (SET) is a method of acquiring, processing, and reporting patient physiological data. It combines innovative sensor technologies and proprietary signal processing algorithms with adaptive filters that work in real time to ensure accurate readings through all patient conditions, including mo-tion. Masimo was the first company to solve the problem of motion-related interference, and it has received numerous awards and pat-ents for its contributions to the field of non- invasive patient monitoring.
