First device to noninvasively measure carbon monoxide in the blood
28 February 2005
Irvince, Calif., USA. Masimo, 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.
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 (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 (SCO(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
products.
