IRVINE, Calif.--(BUSINESS WIRE)-- Masimo (NASDAQ: MASI) announced today that RD SET™ sensors with Masimo Measure-through Motion and Low Perfusion™ SET^® pulse oximetry have received FDA clearance with improved SpO₂ accuracy specifications for all patients > 3 kg. RD SET single-patient-use sensors with the improved accuracy specifications are now available. The new RD SET sensors’ SpO₂ accuracy specifications during patient motion have improved for adult, pediatric, and infant patients to 1.5% (at 1 SD), compared to previous accuracy specifications of 3%.

In addition to offering improved accuracy, RD SET sensors are designed to enhance patient comfort, optimize clinician workflows, and help hospitals meet green initiatives. The sensors are lightweight and have a flat, soft cable with smooth edges, so that they lie comfortably on a patient’s hand or foot. The sensors feature an intuitive sensor-to-cable connection. Their lightweight design results in up to 84% less waste, and their sleek, recyclable packaging reduces storage and shipping space.

The clinical benefits of Masimo’s revolutionary SET^® pulse oximetry have been demonstrated in a variety of clinical conditions. Studies have shown:

• Masimo SET^® helped significantly reduce rates of severe retinopathy of prematurity (ROP) and the need for laser treatment.¹
• Masimo SET^® enabled pulse oximetry screening for critical congenital heart disease (CCHD), helping save many full-term newborns’ lives whose disease would otherwise have gone undiagnosed.^2-4
• With Masimo SET^® on post-surgical wards, rescue calls and ICU transfers were reduced by 65% and 48%, respectively.⁵ Post-operative continuous surveillance monitoring, combined with Masimo SET^®, led to zero preventable deaths or brain damage due to opioids over five years.⁶

Joe Kiani, founder and CEO of Masimo, said, “We’re delighted to be able to announce our continued innovation in our foundational SET^® pulse oximetry. Thanks to the brilliance and dedication of our engineers and the continuing support of our customers, we’ve been able to once again raise the standard for pulse oximetry performance. Even though no one has been able to create pulse oximetry that outperforms SET^®, we have not allowed that to stop us from continuing our pursuit of perfecting the technology. We have significantly improved our accuracy during motion and this is just the start of further improvements in what clinicians can expect from pulse oximetry.”

In addition to excellent accuracy and reliability, the SET^® platform with rainbow^® is also the only oximetry technology that also allows clinicians to measure physiological parameters such as total hemoglobin, carboxyhemoglobin, methemoglobin, and PVi^®.

About Masimo

Masimo (NASDAQ: MASI) is a global leader in innovative noninvasive monitoring technologies. Our mission is to improve patient outcomes and reduce the cost of care. In 1995, the company debuted Masimo SET^® Measure-through Motion and Low Perfusion™ pulse oximetry, which has been shown in multiple studies to significantly reduce false alarms and accurately monitor for true alarms. Masimo SET^® has also been shown to help clinicians reduce severe retinopathy of prematurity in neonates,¹ improve CCHD screening in newborns,³ and, when used for continuous monitoring with Masimo Patient SafetyNet™ in post-surgical wards, reduce rapid response activations and costs.^5-7 Masimo SET^® is estimated to be used on more than 100 million patients in leading hospitals and other healthcare settings around the world,⁸ and is the primary pulse oximetry at 9 of the top 10 hospitals listed in the 2018-19 U.S. News and World Report Best Hospitals Honor Roll.⁹ In 2005, Masimo introduced rainbow^® Pulse CO-Oximetry technology, allowing noninvasive and continuous monitoring of blood constituents that previously could only be measured invasively, including total hemoglobin (SpHb^®), oxygen content (SpOC™), carboxyhemoglobin (SpCO^®), methemoglobin (SpMet^®), Pleth Variability Index (PVi^®), and more recently, Oxygen Reserve Index (ORi™), in addition to SpO₂, pulse rate, and perfusion index (Pi). In 2014, Masimo introduced Root^®, an intuitive patient monitoring and connectivity platform with the Masimo Open Connect^® (MOC-9^®) interface, enabling other companies to augment Root with new features and measurement capabilities. Masimo is also taking an active leadership role in mHealth with products such as the Radius-7^® wearable patient monitor, iSpO₂^® pulse oximeter for smartphones, and the MightySat™ fingertip pulse oximeter.
