Maricopa Integrated Health System Installs Masimo Patient SafetyNet™ System for Improved Oversight of General Floor

PHOENIX and IRVINE, Calif., Nov. 15, 2012 /PRNewswire/ --Maricopa Integrated Health System, among the most trafficked hospital systems in Arizona with more than 500 licensed beds, and Masimo (NASDAQ: MASI) today announced that Maricopa has deployed Masimo Patient SafetyNet™, clinically shown to help improve patient outcomes and save money.¹

The installation is part of the nationally recognized healthcare organization's standardization to Masimo SET^® Measure-Through Motion and Low Perfusion pulse oximetry and rainbow^® SET^® Pulse CO-Oximetry.

Maricopa joins a growing list of leading health systems using Patient SafetyNet, which can help ensure patient safety by noninvasively and continuously measuring and tracking their underlying physiological conditions and detect changes or abnormalities that signal declining health status in real-time. When changes occur in the measured values, which may indicate deterioration in the patient's condition, the system automatically sends wireless alerts directly to clinicians – prompting a potentially lifesaving response to the patient's bedside.

"Patients and their families can be confident that with the Masimo Patient SafetyNet system, they are being monitored at the bedside even when clinical staff is not in the room," said Michael O'Reilly, MD, Masimo's Chief Medical Officer. "We are honored that Maricopa Integrated Health System has selected Masimo technology to help protect their patients."

Maricopa patients also will benefit from breakthrough rainbow^® technology that allows clinicians to measure multiple blood constituents, respiration rate, and other physiological parameters without invasive blood draws and time-consuming laboratory analysis. Parameters in use include total hemoglobin (SpHb^®), oxygen content (SpOC™), carboxyhemoglobin (SpCO^®), methemoglobin (SpMet^®), and Pleth Variability Index (PVI^®), in addition to the Measure-Through Motion and Low Perfusion performance of Masimo SET^® oxyhemoglobin (SpO₂), perfusion index (PI), and pulse rate (PR). The pulse oximetry standard-of-care at leading hospitals worldwide, Masimo SET^® virtually eliminates false alarms² and increases a clinician's ability to detect life-threatening events.³

Blood transfusions carry risks, including a significant link to mortality, infection, and adult respiratory distress syndrome.⁴ Masimo's SpHb has been clinically shown to help anesthesiologists reduce the frequency of blood transfusions.⁵

"I've found total hemoglobin (SpHb) to be particularly useful when I'm in the OR because it offers a continuous measurement," said William Johnson, MD, Chairman of the Department of Anesthesiology at Maricopa Medical Center. "In cases where there's insidious blood loss during some of the longer surgeries, you can keep track of the trend. And when there's relatively rapid loss, the Masimo monitor produces a graph to show hemoglobin falling. In either of those extremes, the ability to track blood loss may make you more inclined not to give a unit of blood when you can predict hemodynamics. When used properly, SpHb can reduce the urge to give blood when it's not absolutely necessary, which can improve patient safety and outcomes."

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^TM), carboxyhemoglobin (SpCO^®), methemoglobin (SpMet^®), and Pleth Variability Index (PVI^®), in addition to SpO₂, pulse rate, and perfusion index (PI).

Forward Looking Statements
This press release includes forward-looking statements as defined in Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934, in connection with the Private Securities Litigation Reform Act of 1995.
