Masimo Corporation Announces Masimo Rainbow SET the World's First Pulse CO-Oximeter

First Device to Noninvasively Measure Carbon Monoxide in the Blood

Will Debut at the EMS Today Conference

Feb 28, 2005, 00:00 ET from Masimo Corporation

    IRVINE, Calif., Feb. 28 /PRNewswire/ -- Masimo(R), the inventor of
 Read-Through Motion & Low Perfusion Pulse Oximetry, today announced the next
 breakthrough in the world of noninvasive patient monitoring; Masimo
 Rainbow(TM) SET Pulse CO-Oximetry(TM).  Masimo Rainbow SET employs
 revolutionary sensor, hardware and software designs that are able to collect
 more information noninvasively than previously believed possible.  With the
 introduction of Masimo SET(R) (Signal Extraction Technology) in 1996, Masimo
 solved the problem clinicians faced with inaccuracy and false alarms
 associated with pulse oximetry due to patient motion, low perfusion and other
 challenging conditions.  Now, with Masimo Rainbow SET, Masimo ushers a new era
 where carbon monoxide and potentially other vital parameters can be safely and
 accurately monitored continuously and noninvasively.
     Rainbow technology is based on system theory and adaptive signal
 processing algorithms first introduced to the medical community with Masimo
 SET in 1996.  Rainbow technology goes further with the ability to analyze
 information from a sophisticated new sensor technology that employs eight
 wavelengths.  The Rainbow sensor generates an extraordinarily rich
 physiological data stream, which opens the door to monitoring additional
 parameters that presently require costly, inconvenient blood gas measurements
 that are often unavailable when the information is needed most.
     In addition to Rainbow SET's current ability to noninvasively monitor the
 level of carbon monoxide in the blood, Masimo's engineering team is utilizing
 the additional data delivered by the Rainbow technology platform and sensors
 to qualify and document an array of new potential measurements and
 applications.  The Masimo Rainbow SET platform has been developed with the
 intent to deliver accurate monitoring of parameters like methemoglobin
 (SpMet(TM)), and fractional arterial oxygen saturation (SpaO2(TM)), all
 measured noninvasively.
     The first product built with Rainbow technology, Rad-57(TM), will be
 debuted March 19 at the 2005 EMS Today convention in Philadelphia.  The Rad-57
 is a handheld Signal Extraction Pulse CO-Oximeter(TM) that noninvasively
 measures the percentage of hemoglobin bound with carbon monoxide (SpCO(TM)).
 In the past, accurate measurement of carbon monoxide in the body required
 invasive procedures, and simply was not practical in most emergency situations
 where it is often needed.  The Rad-57 will provide all clinicians and
 emergency workers reliable information on carbon monoxide poisoning in
 seconds, enabling timely decisions on appropriate treatment.  Besides SpCO,
 the Rad-57 also measures SpO2, perfusion index and pulse rate utilizing Masimo
 SET pulse oximetry, with its proven ability to read through motion and low
 perfusion.  Rad-57 utilizes MX-1(TM), the new Masimo Rainbow SET Pulse
 CO-Oximetry OEM platform.  Masimo will make MX-1 available to its OEM partners
 who wish to provide Pulse CO-Oximetry to their customers.
     "Ten years ago, Masimo broke new ground by making pulse oximeters reliable
 during motion and low perfusion, using their Signal Extraction Technology.
 Masimo will advance pulse oximetry again with their new Rainbow technology.
 In the 25-year history of pulse oximetry, no one has produced an instrument
 that will function accurately on patients suffering from carbon monoxide
 poisoning," reports Dr. Steven Barker, Head of the Department of
 Anesthesiology at the University of Arizona College of Medicine.  "As shown in
 my studies on animals (Anesthesiology 66:677-79, 1987), conventional pulse
 oximeters cannot distinguish between oxygenated hemoglobin and
 carboxyhemoglobin, falsely reporting both as oxygenated.  Since
 carboxyhemoglobin is a toxic form that can cause death at levels greater than
 50%, the development of a pulse oximeter that can separately measure
 carboxyhemoglobin and oxyhemoglobin will be a major advance in healthcare.
 Such a device would soon become a standard of care in emergency rooms,
 ambulances, and many other critical care settings."
     Joe E. Kiani, CEO of Masimo stated, "Solving unsolvable problems has been
 the driving force behind Masimo's culture and mission.  Our mission has been
 to Improve Patient Care and Reduce Cost of Care by Taking Noninvasive Patient
 Monitoring to New Sites and Applications.  Masimo and Masimo Labs engineering
 team have been working for years to introduce the Rainbow platform.  Rainbow
 represents a new era in noninvasive monitoring, and we are eager to deliver
 these new solutions that we know can save lives and improve outcomes for so
 many patients.  We are proud to once again introduce the next evolution of
 pulse oximetry."
     Beginning in March, all Masimo Radical pulse oximeters will be shipped
 "Rainbow Ready."  Rainbow Ready Radical oximeters include Masimo SET
 technology; and will permit customers to add Rainbow-specific parameters such
 as SpCO and additional potential parameters via simple software upgrade
 options.  In addition, Masimo is creating a Rainbow upgrade program to allow
 its customers who purchased Radicals prior to the availability of this new
 platform to economically upgrade to Rainbow SET Pulse CO-Oximetry.  Customers
 should contact their Masimo representative for complete details.  In the
 months ahead, Masimo will introduce Rainbow SET compatibility in other new
     About Masimo
     Masimo, founded in 1989, is the inventor and leader of Signal Extraction
 Pulse CO-Oximetry.  Masimo develops, licenses, and markets advanced medical
 signal processing technologies and products for the non-invasive monitoring of
 vital signs.  Masimo Signal Extraction Technology, or Masimo SET, represents
 the standard of care for pulse oximeters.  With its introduction in 1996,
 Masimo SET overcame data dropouts, false alarms and inaccurate measurements
 due to patient motion, low perfusion and other challenging conditions.  Over
 100 clinical studies support the conclusion that Masimo SET is the most
 effective pulse oximeter in the world.
     With the advent of Rainbow Technology, Masimo ushers a new era for
 noninvasive monitoring, where patients at risk of respiratory and cardiac
 complications, carbon monoxide poisoning and other life threatening diseases
 can be safely, noninvasively and accurately monitored with Pulse CO-Oximetry.
