IRVINE, Calif., Oct. 17 /PRNewswire-FirstCall/ -- Masimo, the inventor of Pulse CO-Oximetry(TM) and Measure-Through-Motion-and-Low-Perfusion pulse oximetry, announced today that five new independent and objective studies demonstrating Masimo PVI to be highly predictive of patient fluid status will be presented at the American Society of Anesthesiology (ASA) Annual Meeting in Orlando, Fla., October 19-21, 2008.

Fluid administration is critical to optimizing patient status and enabling end organ preservation, but traditional methods to guide fluid administration are invasive and often fail to predict fluid responsiveness. PVI has been shown to predict fluid responsiveness in mechanically ventilated patients under general anesthesia during surgery, and may help clinicians optimize fluid administration and improve patient outcomes.(2-4)

Also at ASA for the first time, Masimo will be showcasing live demonstrations of the first-ever noninvasive and continuous hemoglobin (SpHb) and Oxygen Content (SpOC) monitor. SpHb provides instantaneous hemoglobin measurements that may facilitate faster, easier, safer, and better clinical decisions by allowing clinicians to more quickly detect chronic or acute anemia, identify occult bleeding earlier, and more effectively manage blood transfusions. While oxygen saturation (SpO2) and hemoglobin are considered critical parameters for patient management, neither parameter by itself can indicate the actual amount of oxygen in the blood. However, now with Masimo Rainbow SET Pulse CO-Oximetry, SpHb and SpO2 can be used together to provide clinicians with the first-and-only technology for real-time and noninvasive oxygen content (SpOC(TM)) monitoring, providing a more complete picture of oxygenation status and potentially allowing earlier indication of when a patient crosses the threshold into a critical oxygen deficit.

The following studies will be presented at the ASA Annual Meeting:

Impact of PEEP on Perfusion Index and Plethysmographic Variability Index(1)-A1068, Presented: October 20, 2008, 2:00-4:30 p.m., Room Hall E2-Area M

Ability of Pleth Variability Index to Non Invasively Predict the Hemodynamic Effects of PEEP(2)-A1608, Presented: October 22, 2008, 8:00-9:30 a.m., Room 230C

Ability of Pleth Variability Index to Detect Preload Changes in Orthotopic Liver Transplant Patients(3)-A1605, Presented: October 22, 2008, 8:00-9:30 a.m., Room 230C

Pleth Variability Index: A Noninvasive Device for Fluid Responsiveness Assessment during Anesthesia(4)-A1604, Presented: October 22, 2008, 8:00-9:30 a.m., Room 230C

Impact of Lower Extremity Nerve Blockage on Oximeter Perfusion Index & Pleth Variability Index(5)-A1603, Presented: October 22, 2008, 8:00-9:30 a.m., Room 230C

Michael O'Reilly, MD, EVP of Medical Affairs at Masimo, stated; "These studies add to the evidence showing that PVI can provide clinicians with an effective and efficient noninvasive method of continuously measuring their patient's fluid volume. This should enable more accurate fluid administration decisions -- allowing clinicians to add a level of certainty and immediacy toward managing intravascular fluid volumes and cardiac output both inside and outside of the operating room."

PVI is available as part of Masimo Rainbow SET(R) Pulse CO-Oximetry(TM) -- the first-and-only technology platform to noninvasively measure blood constituents and fluid responsiveness that previously required invasive procedures, including: noninvasive & continuous total hemoglobin (SpHb(TM)), oxygen content (SpOC(TM)), carboxyhemoglobin (SpCO(R)), methemoglobin (SpMet(R)) and Pleth Variability Index (PVI), in addition to the 'gold standard' measure-through-motion-and-low-perfusion performance of Masimo SET(R) Oxygen Saturation (SpO2), Pulse Rate (PR) and Perfusion Index (PI).

About Masimo

Masimo (Nasdaq: MASI) develops innovative 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 demonstrate Masimo SET provides the most reliable SpO2 and pulse rate measurements even under the most challenging clinical conditions, including patient motion and low peripheral perfusion. In 2005, Masimo introduced Masimo Rainbow SET Pulse CO-Oximetry, a breakthrough noninvasive blood constituent monitoring platform that can measure many blood constituents that previously required invasive procedures. Masimo Rainbow SET continuously and noninvasively measures total hemoglobin (SpHb(TM)), oxygen content (SpOC(TM)), carboxyhemoglobin (SpCO(R)), methemoglobin (SpMet(R)), and PVI(TM), in addition to oxyhemoglobin (SpO2), pulse rate (PR), and perfusion index (PI), allowing early detection and treatment of potentially life-threatening conditions. Founded in 1989, Masimo has the mission of "Improving Patient Outcomes and Reducing Cost of Care by Taking Noninvasive Monitoring to New Sites and Applications."
