Masimo rainbow sensors use a multi-wavelength sensor to distinguish between
oxygenated blood, deoxygenated blood, blood with carbon monoxide, oxidized
blood and blood plasma.
oxygenated blood, deoxygenated blood, blood with carbon monoxide, oxidized
blood and blood plasma.
Masimo rainbow sensors utilize various light-emitting diodes (LEDs) that pass
light through the site to a diode (detector). Signal data is obtained by passing
various visible and infrared lights (LEDs, 500 to 1400nm) through a capillary bed
(for example, a fingertip, a hand, a foot) and measuring changes in light
absorption during the blood pulsatile cycle. This information may be useful to
clinicians. The maximum radiant power of the strongest light is rated at 25
mW. The detector receives the light, converts it into an electronic signal and
sends it to the Masimo circuit board for calculation.

(SpMet [%]), total hemoglobin concentration (SpHb [g/dL]) and pulse rate (PR).
The SpCO, SpMet and SpHb measurements rely on a multi-wavelength
calibration equation to quantify the percentage of carbon monoxide and
methemoglobin and the concentration of total hemoglobin in arterial blood.

rainbow technology (noninvasive) are compared to drawn whole blood (invasive)
measurements by blood gas and/or laboratory CO-Oximetry methods, caution
should be taken when evaluating and interpreting the results.
