Atom Medical Adopts Masimo Rainbow SET Technology

April 16, 2008
IRVINE, Calif., April 16, 2008 /PRNewswire-FirstCall via COMTEX News Network/ -- Masimo (Nasdaq: MASI), the inventor of Pulse CO-Oximetry and Measure-Through-Motion-and-Low-Perfusion pulse oximetry, today announced an agreement with Atom Medical Corporation, a leading global manufacturer of neonatal products and technologies, to integrate Masimo Rainbow SET Pulse CO-Oximetry into its current and future product solutions.

"Since standardizing on Masimo technology more than 10 years ago, our neonatal monitoring solutions and customers have greatly benefited from the superior performance of Masimo SET pulse oximetry," said Kazuo Matsubara, President of Atom Medical. "Now, with the groundbreaking capabilities of Masimo Rainbow SET and its ability to provide vital measurements that previously required invasive lab procedures, we are confident that the clinical community which we serve will experience even greater clinical and financial benefits from our solutions."

Masimo Rainbow SET is the first and only technology platform capable of noninvasively and continuously measuring total hemoglobin (SpHbTM) and oxygen content (SpOCTM) -- both measurements pending FDA and other regulatory clearances -- as well as carboxyhemoglobin (SpCO(R)), methemoglobin (SpMet(R)), and pleth variability index (PVITM), in addition to oxyhemoglobin (SpO2), perfusion index (PI), and pulse rate (PR).

Masimo Rainbow SET has the potential to help clinicians save lives through more rapid diagnosis of potentially life-threatening conditions, allowing faster treatment decisions and improved patient outcomes. The latest Masimo Rainbow SET measurement, SpHb, may enable medical personnel in both hospital and outpatient settings to quickly identify anemia or blood loss without having to draw blood or wait for lab results.

In neonatal settings, the ability to continuously and noninvasively measure a patient's methemoglobin levels is especially important due to the risks associated with the use of inhaled nitric oxide (iNO) therapy to treat hypoxic respiratory failure in newborns, which has been shown to induce methemoglobinemia. According to the American Academy of Pediatrics, "infants who receive iNO therapy should be monitored according to institutionally derived protocols designed to avoid the potential toxic effects associated with iNO administration. These effects include methemoglobinemia (secondary to excess nitric oxide concentrations), direct pulmonary injury (attributable to excess levels of nitrogen dioxide), and ambient air contamination."(1)

Masimo Chairman and CEO, Joe E. Kiani, said, "Atom is a long-time Masimo partner dedicated to developing innovative solutions for the challenging neonatal clinical setting. The addition of Masimo Rainbow SET affirms their position as a leading global provider of advanced neonatal product solutions, leveraging breakthrough technologies to improve the quality of care for the tiniest of patients. We commend Atom for their commitment to patient care and product innovation."

About Masimo

Masimo (NASDAQ: MASI) develops innovative 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 demonstrate Masimo SET provides the most reliable SpO2 and pulse rate measurements even under the most challenging clinical conditions, including patient motion and low peripheral perfusion. In 2005, Masimo introduced Masimo Rainbow SET, a breakthrough noninvasive blood constituent monitoring platform that can measure many blood constituents that previously required invasive procedures. Rainbow SET continuously and noninvasively measures total hemoglobin (SpHb(TM)) and oxygen content (SpOC(TM)) (both pending regulatory clearances), carboxyhemoglobin (SpCO(R)), methemoglobin (SpMet(R)), and PVI(TM), in addition to oxyhemoglobin (SpO2), pulse rate (PR), and perfusion index (PI), allowing early detection and treatment of potentially life-threatening conditions. Founded in 1989, Masimo has the mission of "Improving Patient Outcomes and Reducing Cost of Care by Taking Noninvasive Monitoring to New Sites and Applications."

Forward Looking Statements

This press release may include forward-looking statements. These forward-looking statements are based on current expectations about future events affecting us and are subject to uncertainties and factors, all of which are difficult to predict and many of which are beyond our control, including: risks related to our assumption that this agreement with Atom and their adoption of Masimo technology will serve to substantially increase revenues, risks related to our assumption that Masimo's new noninvasive measurements -- total hemoglobin (SpHb(TM)) and oxygen content (SpOC(TM)) -- will deliver a sufficient level of clinical improvement over alternative hemoglobin testing capabilities to allow for rapid adoption of the technology and risks related to our assumptions regarding the timing or commercial availability of SpHb and SpOC, and will be timely cleared, if ever, by appropriate regulatory bodies, as well as other factors discussed in the "Risk Factors" section of our annual report on Form 10-K for the year ended December 29, 2007, filed with the Securities and Exchange Commission on March 4, 2008. Although we believe that the expectations reflected in our forward-looking statements are reasonable, we do not know whether our expectations will prove correct. You are cautioned not to place undue reliance on these forward- looking statements, which speak only as of the date hereof.
