Super Sensor Measures Multiple Physiologic Parameters

An advanced, reusable, spot-check sensor is the first ever to noninvasively measure total hemoblogin (SpHb), carboxyhemoglobin (SpCO), methemoglobin (SpMet), and arterial oxygen saturation (SpO2).

The Masimo (Irvine, CA, USA) rainbow Super DCI-mini sensor is intended for patients weighing 3 kg or more, and can be applied to an adult or pediatric finger, or to an infant finger, thumb, or great toe. The small, lightweight sensor has a flexible cable to provide stability and comfort during monitoring. The sensor features Masimo rainbow SET measure-through-motion and low perfusion technology with expanded multiple physiologic measurements, which apart from SpHb, SpCO, SpMet, and SpO2, also include pulse rate (PR), perfusion index (Pi), and pleth variability index (PVi).


With the aid of motion tolerance technology, SpHb results can be displayed in as few as 30 seconds, with field performance enhanced for lower hemoglobin ranges; SpCO monitoring may lead to the identification of elevated carbon monoxide (CO) levels that might otherwise go undetected in front-line settings, such as triage and emergency care; and SpMet can help clinicians monitor for methemoglobin in care areas where the drugs that cause methemoglobinemia are most common, such as procedure labs and the operating room.

“This is an exciting day for us, and hopefully a great opportunity to improve patient care. Since the invention of rainbow technology, we have been wanting our customers to be able to measure SpCO, SpMet, SpHb and SpO2 simultaneously; now they can!” said Joe Kiani, founder and CEO of Masimo. “We believe the rainbow Super DCI-mini sensor will be especially valuable for use in triage and emergency care situations. We plan to introduce a continuous measurement version of the Super Sensor in the near future.”

Masimo SET is a noninvasive sensor technology that uses more than seven wavelengths of light to acquire blood constituent data based on light absorption. Advanced signal processing algorithms and unique adaptive filters work together to isolate, identify and quantify various hemoglobin species, delivering blood measurement results in numerical values. Basic Masimo SET measurements include SpO2, PR, PI, and PVI, a measure of the dynamic changes in perfusion index that occur during the respiratory cycle.
