HAMILTON MEDICAL Unveils Closed-Loop Ventilator Integrating Masimo SET® Pulse Oximetry to Facilitate Advanced Adaptive Ventilation Support

Bonaduz, Switzerland & Irvine, California – October 12, 2012 – HAMILTON MEDICAL AG, a leader in intensive care ventilators and closed-loop technology, and Masimo (NASDAQ: MASI), the inventor of breakthrough SET® Measure-Through Motion and Low Perfusion pulse oximetry, announced today a purchasing and licensing agreement, and associated international launch of the integration of Masimo's blood oxygenation (SpO2) measurement technology with HAMILTON MEDICAL's fully closed-loop mechanical ventilation systems. INTELLiVENT®-ASV is the world's first fully closed-loop ventilation solution, automating ventilation and oxygenation in one system.

HAMILTON MEDICAL will unveil the new system integration, available in HAMILTON-S1 and HAMILTON-G5 ICU ventilators, at the European Society of Intensive Care Medicine (ESICM) LIVES 2012 congress in Lisbon, Portugal, October 13-17, at exhibit booth 23.

With the integration of Masimo SET® extended measurement options, HAMILTON MEDICAL enhances its ventilation support options for the innovative HAMILTON-S1 and HAMILTON-G5 ventilators. This offers clinicians the choice of using an SpO2 technology that they are used to working with. Masimo SET® has been proven to provide accurate SpO2 values under real-world challenging conditions, including patient motion, patient transport, and low perfusion. "This performance is of great benefit to INTELLiVENT®-ASV closed-loop operation," said Jens Hallek, VP and COO of HAMILTON MEDICAL AG in Bonaduz.

The integration of Masimo SET® with HAMILTON MEDICAL ventilators expands the options for SpO2 technologies. SpO2 measurements are used by INTELLiVENT®-ASV, and are also available separately as monitored parameters. HAMILTON MEDICAL increases the ease of use with a dedicated sensor adapter for Masimo. The adapter mounts easily on all standard rails and includes a storage position for CAPNOSTAT® CO2 sensors. It also offers the ability to manage the SpO2 and CO2 sensor cables to avoid cable entanglements.

“Masimo and HAMILTON MEDICAL share a passionate mission for improving patient outcomes while reducing the cost of care,” said Rick Fishel, President of Masimo Worldwide OEM Business & Corporate Development. “Today’s announcement is good news for patients and clinicians. HAMILTON MEDICAL’S INTELLiVENT®-ASV should help patients recover more comfortably and more quickly with less clinician intervention.”

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 required invasive procedures, including total hemoglobin (SpHb®), oxygen content (SpOCTM), carboxyhemoglobin (SpCO®), methemoglobin (SpMet®), and Pleth Variability Index (PVI®), in addition to SpO2, pulse rate, and perfusion index (PI).
