Masimo Announces CE Mark and Limited Market Release of

NEUCHATEL, SWITZERLAND--(Marketwired - Jul 29, 2014) - Masimo ( NASDAQ : MASI ) today announced CE Mark and limited market release of Radius-7™ for the Root ^® patient monitoring and connectivity platform, the first and only wearable, wireless monitor with Masimo's breakthrough rainbow ^® SET ^® technology, enabling early identification of clinical deterioration while offering patients continuous monitoring with freedom of movement.

With rainbow ^® SET ^® noninvasive measurements, Radius-7 with Root can alert clinicians -- at the bedside or remotely, through the Masimo Patient SafetyNet ™ remote monitoring and notification system -- of critical changes in a patient's oxygen saturation, pulse rate, respiration rate, or haemoglobin that may indicate pulmonary, cardiac, or internal bleeding problems. Lightweight at only 155g (0.34 lbs), the Radius-7 attaches to the patient's arm or can be placed alongside the patient in their bed, allowing untethered monitoring while they are in bed or out. With no need to disconnect and reconnect the cable to get out of bed, the Radius-7 reduces the need for nursing assistance. And the Radius-7's wireless communication functionality -- either short-range via Bluetooth back to Root or with upgradeable WiFi for long-range communication* -- ensures the patient can be continuously monitored and connected to caregivers wherever they are in the hospital.

Studies have shown that patient mobility is a key factor in more rapid patient recovery. ¹ Radius-7 allows clinicians to mobilize their patients.

"With this new technology we have made another important step to improve patient safety," said Caroline Stade, chief nursing officer at University Children's Hospital Basel (UKBB) in Basel, Switzerland. "Children can be cared for and move about as they are able, while remaining under seamless, clinical surveillance. This makes parents, and of course, nurses and clinicians, feel better about the quality of care offered to our pediatric patients."

"In the past, wearable patient monitoring offered only limited measurements that were often plagued by false alarms. Radius-7 allows untethered clinically relevant patient monitoring," said Masimo founder and CEO Joe Kiani. "We expect Radius-7 and Root to change how hospitals think about monitoring, ushering in a new level of patient safety."

Radius-7 is not available for sale in the United States.

*The configuration for long-range communication is pending CE marking.

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 SpO ₂ , 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 ^® ."
