Masimo to Launch Rainbow Lite Sensors with Oxygen Reserve Index

Rainbow Lite Sensors with Oxygen Reserve Index

Masimo is set to release new RD rainbow Lite SET sensors for measuring the company’s proprietary Oxygen Reserve Index (ORi) and Pleth Variability Index (PVi) that relies on multiple wavelengths of light.

Masimo, an American Irvine, California-based manufacturer of noninvasive patient monitoring technologies is going to offer rainbow Lite SET sensors, which is on top of pulse oximetry capabilities. The technology allows for live fluid responsiveness assessment at a cost much lower than invasive techniques or even Masimo’s own rainbow sensors.

According to Oxygen Concentrators Market report published by Coherent Market Insights, recently oxygen cylinders was the gold standard method for oxygen delivery to patients with chronic respiratory disorders or hypoxia. The new RD rainbow Lite SET sensors can allows live fluid responsiveness assessment for oxygen. According to the product description by company, ORi is the first noninvasive and continuous parameter to provide insight into a patient’s oxygen reserve in the moderate hyperoxic range. In conjunction with SET pulse oximetry, ORi may provide advanced warning of impending desaturation, which may allow clinicians to intervene sooner.

Results from a study of 25 pediatric patients were described in the announcement, which showed that ORi helped to spot desaturations a median of about 30 seconds before noted on SpO2. A larger study of adult patients with arterial catheterization and intraoperative blood gases analyses before surgery, demonstrated a relationship between changes in PaO2 and changes in ORi. It also seems to point to ORi helping to watch the oxygen reserve in titrating patients on oxygen.
