Masimo Rainbow SpO2 Technology And Testing
Masimo Rainbow is the first technology to noninvasively measure blood constituents and fluid responsiveness that previously required invasive procedures. Besides measuring arterial oxygensaturation level (SpO2) and pulse rate, Rainbow technology measures following parameters as well: Hemoglobin (SpHb), Carboxyhemoglobin (SpCO) and Methemoglobin (SpMet).
Traditional pulse oximeters use wavelengths of two lights (infrared light at 940 nm and red light at 660 nm), which are absorbed differently by either oxyhemoglobin or the reduced hemoglobin to measure SpO2 concentration. Two-wavelength oximeters cannot measure total hemoglobin or dyshemoglobins. Rainbow sensor technology uses more than 7 wavelengths of light to acquire blood constituent data based on light absorption.
When used with the Masimo Rainbow Test Sensor, ProSim Vital Sign Simulator is the first and only simulator capable of verifying the performance of Masimo Rainbow Oximeters.
