ACUTRONIC Medical Systems Integrates Masimo SET® Pulse Oximetry into fabian HFO Neonatal Critical Care Ventilators for Improved Patient Outcomes

Zurich, Switzerland & Irvine, California – November 22, 2013 – Masimo (NASDAQ: MASI) announced today that ACUTRONIC Medical Systems AG has integrated Masimo SET® Measure-through Motion and Low Perfusion pulse oximetry into ACUTRONIC's fabian HFO Neonatal Critical Care Ventilator for improved patient outcomes.

The fabian HFO, the world's first dedicated Neonatal Ventilator to offer Masimo SET® pulse oximetry, provides continuous display of newborn oxygenation status. Instead of using two separate devices to collect ventilation and oxygenation patient data, clinicians now simply attach the pulse oximetry sensor via USB interface to the fabian HFO to display oxygenation, perfusion index and pulse rate values on the ventilator's colour touchscreen. This combined technology platform will optimize patient assessments and improve workflow, allowing clinicians to spend more valuable time tending to patients.

"The integration of Masimo SET® within ACUTRONIC's fabian HFO ventilator is providing caregivers the ability to better assess their patients' oxygenation status, even during challenging conditions of patient motion and low perfusion," said Roland Hotz, President. "With our fabian HFO neonatal critical care ventilator, we offer clinicians leading technology on a highly versatile platform specifically designed for the most vulnerable of patient populations."

Masimo's President of Worldwide OEM Business & Corporate Development, Rick Fishel stated, "The synergies realized between our companies and products support Masimo's mission to improve patient outcomes and reduce the cost of care by taking noninvasive monitoring to new sites and applications. We are very pleased that Masimo's SET® Pulse Oximetry platform is a key component in ACUTRONIC's new neonatal ventilators."

Masimo SET® pulse oximetry has been shown to virtually eliminate false alarms1 and increase a clinician's ability to detect life-threatening events2 – helping to substantially contribute to improved patient outcomes and patient safety. The clinical accuracy of Masimo SET® pulse oximetry has also been shown to help clinicians significantly reduce retinopathy of prematurity (ROP),3-5 screen for critical congenital heart disease (CCHD) in newborns,6-8 reduce oxygen overdose9,10 and medical errors,11,12 and save lives in post-surgical floors, recovery,2 labor and delivery rooms,13 and ICUs.14

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®."
