Rainbow® Technology · Pulse CO-Oximetry

Seeing more of the blood, with light alone.

Our patented multi-wavelength sensor platform, launched in 2005, is used in hospital monitoring products. Ember is a consumer product and is not a hospital monitoring product.

How it works

Beyond conventional pulse oximetry.

Rainbow II uses multiple additional wavelengths of light and proprietary signal processing to continuously assess oxygen saturation, pulse rate, total hemoglobin, carboxyhemoglobin and methemoglobin from a single sensor.

Noninvasive and continuous

Multiple parameters from a single sensor

Parameters

Eight measurements, noninvasively.

SpO2Oxygen saturation
PRPulse rate
PIPerfusion index
SpHbTotal hemoglobin
SpOCOxygen content
SpMetMethemoglobin
SpCOCarboxyhemoglobin
PViPleth variability index
