Masimo Announces Eight of Top 10 U.S. Hospitals Now Use Masimo SET(R) Pulse Oximetry Technology Hospital-Wide

July 31, 2013

IRVINE, CA -- (Marketwired) -- 07/31/13 -- Masimo (NASDAQ: MASI) today announced that Masimo SET® pulse oximetry is now being used hospital-wide in eight of the top10 hospitals on the current U.S. News & World Report Best Hospitals Honor Roll (2013-2014).

Among the hospitals on the list: Brigham and Women's Hospital, Cleveland Clinic, The Johns Hopkins Hospital, Massachusetts General Hospital, Mayo Clinic, UCLA Medical Center, and UCSF Medical Center.

Masimo SET® pulse oximetry has been shown to virtually eliminate false alarms1 and increase a clinician's ability to detect life-threatening events2 -- helping to substantially contribute to improved patient outcomes and patient safety. The clinical accuracy of Masimo SET® pulse oximetry has also been shown to help clinicians significantly reduce retinopathy of prematurity3-5, screen for critical congenital heart disease in newborns6-8, reduce oxygen overdose9, 10 and medical errors11, 12, and save lives in post-surgical floors, recovery2, labor and delivery rooms13, and ICUs14.

More than 100 independent clinical studies have confirmed that Masimo SET® technology allows clinicians to accurately monitor blood oxygen saturation in the most challenging conditions, including patient movement and low peripheral perfusion.15

"We are proud to call these great institutions, our customers; and, we will continue to do our best to serve not only these world-renowned clinical centers, but all of our caring clinical customers, so that they can serve their patients the best way possible," said Masimo Founder and CEO, Joe Kiani.

About Masimo
Masimo (NASDAQ: MASI) is the global leader in innovative noninvasive monitoring technologies that significantly improve patient care -- helping solve "unsolvable" problems. In 1995, the company debuted Measure-Through Motion and Low Perfusion pulse oximetry, known as Masimo SET®, which virtually eliminated false alarms and increased pulse oximetry's ability to detect life-threatening events. More than 100 independent and objective studies have shown that Masimo SET® outperforms other pulse oximetry technologies, even under the most challenging clinical conditions, including patient motion and low peripheral perfusion. In 2005, Masimo introduced rainbow SET® Pulse CO-Oximetry technology, allowing noninvasive and continuous monitoring of blood constituents that previously required invasive procedures, including total hemoglobin (SpHb®), oxygen content (SpOC™), carboxyhemoglobin (SpCO®), methemoglobin (SpMet®), and Pleth Variability Index (PVI®), in addition to SpO2, pulse rate, and perfusion index (PI).
