First Study to Expand PVI Utility Beyond the OR Presented at the 29th International Symposium on Intensive Care and Emergency Medicine in Brussels

IRVINE, Calif., March 31 /PRNewswire-FirstCall/ -- Masimo (Nasdaq: MASI), the inventor of Pulse CO-Oximetry(TM) and Measure-Through Motion and Low-Perfusion pulse oximetry, announced today that a new independent clinical study demonstrates Masimo PVI to be an "accurate index of fluid responsiveness" for critical care patients in the intensive care unit (ICU).(1) The study, presented at the 29th International Symposium on Intensive Care and Emergency Medicine on March 25, 2009, in Brussels, Belgium, is the first to show the potential value of Masimo PVI to predict fluid responsiveness beyond the operating room (OR) into the ICU.

Critically-ill patients are at great risk for volume depletion. Fluid administration is critical to optimizing oxygen delivery to organs and tissues, but giving too much fluid can induce life-threatening adverse effects. Therefore, parameters that aid clinicians in fluid management decisions may help improve patient outcomes. The most validated predictor of fluid responsiveness is pulse pressure variation (¿PP). However, this parameter requires an invasive arterial pressure catheter, which is not appropriate for all patients, or special software, which is not available in all monitoring systems. Masimo PVI is not only noninvasive, enabling easy application on almost any patient, but is also easily obtained from existing or field upgradable Masimo Rainbow SET(R) pulse oximeters and sensors that are already being used to monitor SpO2 and pulse rate.

In the study, Marc Feissel, MD, and colleagues at Le Centre Hospitalier Belfort-Montbeliard (CHBM) in Belfort, France, along with a team of researchers from Assistance Publique-Hop
