Masimo Announces MX-5 OEM Circuit Board, Offering Breakthrough rainbow(R) Pulse CO-Oximetry(TM) Measurements at 250mW

Low Power Consumption rainbow(R) Pulse CO-Oximetry Circuit Board Enables Design of Smaller, Lighter, More Portable Patient Monitoring Devices Equipped With the High Performance Capabilities of Noninvasive SpHb(R), SpOC(TM), SpCO(R), SpMet(R), and RRa(R) Measurements

IRVINE, CA -- (Marketwired) -- 09/25/14 -- Masimo (NASDAQ: MASI) announced its new MX-5 OEM circuit board, a technology platform that utilizes approximately half the power of previously available rainbow® circuit boards to deliver breakthrough rainbow® Pulse CO-Oximetry noninvasive measurement performance. The MX-5 is also unique in that it can dynamically scale power consumption even further depending on the type of parameters being measured.

Original Equipment Manufacturers (OEM) use Masimo circuit boards to enable noninvasive Masimo SET® Measure-Through Motion and Low Perfusion™ pulse oximetry and rainbow® Pulse CO-Oximetry measurements in their own medical devices and patient monitors. Until now, enabling the powerful noninvasive measurement capabilities of rainbow® Pulse CO-Oximetry required 550 milliwatts of power on average. The reduced power consumption of the new MX-5 circuit board varies between 250 and 320 milliwatts of power on average, depending on the rainbow parameters being measured. This approximately 50% reduction in power consumption is expected to facilitate integration into next-generation patient monitoring solutions that require a more efficient power profile to enable smaller, lighter, and more mobile battery-operated devices.

In addition to the lower power demands compared to previous rainbow® technology boards, the MX-5 adds dynamic power utilization to scale the MX-5's power draw based upon the combination of parameters being monitored to permit even longer battery runtimes. For instance, when monitoring Masimo SET® SpO2 and pulse rate only, average power consumption of the MX-5 is reduced by more than 75% compared to the prior rainbow® technology board. Masimo MX-5 boards are the same size as their MX-3 predecessor, with dimensions of 2" x 2.5," and offer simple drop-in replacement.

Using just 50% of the previous power demand without compromising performance, Masimo MX-5 OEM boards offer full functionality of breakthrough rainbow® technology for noninvasive measurements of total hemoglobin (SpHb®), oxygen content (SpOC™), carboxyhemoglobin (SpCO®), methemoglobin (SpMet®), and acoustic respiration rate (RRa®), in addition to providing Measure-Through Motion and Low Perfusion oxygen saturation (SpO2), pulse rate, and perfusion index (PI) measurement capabilities of Masimo SET® pulse oximetry.

According to Masimo President of Worldwide OEM Business and Corporate Development, Rick Fishel, "The efficient MX-5 board represents Masimo's commitment to continuous technological improvement, which improves OEM ability to integrate rainbow's innovative noninvasive measurements into the design and development of smaller, more portable monitoring devices for a variety of existing and emerging health care applications. Circuitry innovations like the MX-5 allow our OEM partners to compete more aggressively in the marketplace by delivering the noninvasive rainbow Pulse CO-Oximetry capabilities that enable clinicians to make more timely decisions concerning patients' physiological status that may lead to better patient 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 help clinicians 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 ® Pulse CO-Oximetry™ technology, allowing noninvasive and continuous monitoring of blood constituents that previously required invasive procedures; total hemoglobin (SpHb®), oxygen content (SpOC), carboxyhemoglobin (SpCO®), methemoglobin (SpMet®), PVI®, and perfusion index (PI), in addition to measure-through motion SpO2, and pulse rate. In 2008, Masimo introduced Patient SafetyNet™, a remote monitoring and wireless clinician notification system designed to help hospitals avoid preventable deaths and injuries associated with failure to rescue events. In 2009, Masimo introduced rainbow® Acoustic Monitoring, the first-ever commercially available noninvasive and continuous monitoring of acoustic respiration rate (RRa®). Masimo SET® and Masimo rainbow® technologies also can be found in over 100 multiparameter patient monitors from over 50 medical device manufacturers around the world. Founded in 1989, Masimo has the mission of "Improving Patient Outcome and Reducing Cost of Care... by Taking Noninvasive Monitoring to New Sites and Applications®."
