Yale-New Haven Hospital Upgrades to Masimo SET(R) Pulse

NEW HAVEN, CT and IRVINE, CA--(Marketwired - Sep 4, 2014) -   Masimo ( NASDAQ : MASI ) today announced that Yale-New Haven Hospital -- a nonprofit, 1,541-bed tertiary medical center ranked among the best in the U.S. -- has upgraded system-wide to Masimo SET® pulse oximetry , the standard-of-care at leading hospitals around the world.

Yale-New Haven Hospital joins a growing and distinguished global roster of health organizations using Masimo SET ^® Measure-through Motion and Low Perfusion™ pulse oximetry, clinically shown to virtually eliminate false alarms ¹ and help clinicians detect life-threatening events. ² Yale-New Haven Hospital's standardization to Masimo SET ^® pulse oximetry is in keeping with the healthcare organization's dedication to excellence in care and delivering the best possible results for its patients.

"Masimo's SET pulse oximetry technology reduces the measurement error found in other types of pulse oximeters, and in particular offers greater accuracy during states of patient low perfusion -- an important consideration when patients are under anesthesia," said Dr. Douglas Vaughn, M.D., Senior Director of Anesthesia Operations and Medical Director of Perioperative Services at Yale-New Haven Hospital. "We've found SET pulse oximetry to be a valuable tool, both in the operating room and in the intensive care environment."

In addition, a recently published study in the Journal of Perinatology showed that after the neonatal intensive care unit (NICU) at Yale-New Haven Children's Hospital switched to Masimo SET ^® pulse oximetry, there was a 37% lower rate of severe retinopathy of prematurity (ROP), an eye disorder that can cause blindness in premature babies, and a 53% lower rate of ROP requiring surgery. ³

Masimo SET ^® Measure-through Motion and Low Perfusion™ pulse oximetry technology has been proven by more than 100 independent and objective studies and used on more than 100 million patients a year in leading hospitals worldwide, including the top 10 on the U.S. News & World Report Best Hospitals Honor Roll (2014-2015). Masimo SET ^® significantly reduces false alarms (specificity), accurately detects true alarms (sensitivity), and provides measurements when other pulse oximeters fail. ^1,2 Most importantly, Masimo SET ^® pulse oximetry has been clinically proven to improve patient outcomes and reduce cost of care by helping clinicians:

• Decrease retinopathy of prematurity (ROP) in neonates by avoiding giving too much oxygen based on inaccurate SpO ₂ measurements ^3,4
• Increase detection of critical congenital heart disease (CCHD) in newborns by accurately identifying low SpO ₂ measurements ^5,6
• Reduce ventilator weaning time by titrating FiO ₂ faster and reduce arterial blood gas measurements in the ICU through more reliable SpO ₂ measurements ⁷ and
• Decrease rapid response activations and ICU transfers to save lives and costs in post-surgical patients on the medical-surgical floors through earlier identification of patients in distress through low SpO ₂ and abnormal pulse rate measurements. ^2,8

"We are honored to partner with Yale-New Haven Hospital, a highly esteemed healthcare system with a well-deserved reputation for quality care," said Masimo founder and CEO Joe Kiani. "We look forward to helping Yale-New Haven Hospital with its ongoing commitment to improved patient outcomes, while reducing cost of care."

Yale-New Haven was founded as the fourth voluntary hospital in the U.S. in 1826. Today, the hospital's two New Haven-based inpatient campuses include Yale-New Haven Children's Hospital, Yale-New Haven Psychiatric Hospital and Smilow Cancer Hospital. YNHH has a combined medical staff of about 4,500 university and community physicians practicing in more than 100 specialties. YNHH's York Street campus and associated ambulatory sites are Magnet-designated by the American Nurses Credentialing Center.

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 could only be measured invasively, 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).
