Mercy Hospital of Buffalo Expands Use of Masimo Patient SafetyNet(TM) After Pilot Program Shows Reduction in Mortality

September 29, 2014

BUFFALO NY and IRVINE, CA -- (Marketwired) -- 09/29/14 -- Masimo (NASDAQ: MASI) and Mercy Hospital of Buffalo -- one of the largest hospitals in Western New York -- today announced the facility has expanded continuous patient monitoring using Masimo SET® pulse oximetry and the Masimo Patient SafetyNet™ remote monitoring and clinician notification system after seeing reduction in mortality on a pilot-program floor.

At Mercy, Masimo Radical-7 and Rad-87 devices continuously monitor oxygenation with Masimo SET® pulse oximetry and breathing with RRa. Patient Safety net enables the remote monitoring and wireless notification to clinicians of events detected by the bedside devices.

"After conducting a 30-month study of Patient SafetyNet on the hospital's 33-bed medical/surgical 6 McAuley West Unit, the hospital concluded that continuous patient monitoring can benefit all patients and potentially save lives, and so expanded the system throughout the hospital," said Jon Carlson, Mercy Hospital's Director of Respiratory Care.

"The outcome of the trial was a reduction in all-cause mortality on the pilot floor (excluding hospice and comfort care patients from both baseline and study data)," said Carlson. "The Patient SafetyNet monitoring system gives us the opportunity to further enhance patient safety, improve outcomes, and reduce costs by avoiding preventable patient transfers to the ICU."

Carlson noted that a key feature of the Patient SafetyNet system is Masimo SET with ability to measure through challenging patient conditions, including motion as well as low perfusion (or diminished blood flow).

Kathleen Guarino, Mercy Hospital's Vice President of Nursing and Chief Nursing Officer, said Patient SafetyNet is also helping the staff better manage patients' pain. "It provides a 'safety net' by constantly monitoring oxygen saturation and breathing, which is especially important for our patients using narcotic pain medication," she said.

"We are honored and humbled that our technology has helped Mercy Hospital achieve better patient outcomes," said Joe Kiani founder and CEO of Masimo. "We hope all hospitals one day will implement our technology for continuous monitoring of patients, which has been shown to save lives and reduce costs."

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 could only be measured invasively, including total hemoglobin (SpHb®), oxygen content (SpOC™), carboxyhemoglobin (SpCO®), methemoglobin (SpMet®), and Pleth Variability Index (PVI®), in addition to SpO2, pulse rate, and perfusion index (PI).
