IRVINE, Calif.--(BUSINESS WIRE)-- Masimo Corporation (NASDAQ: MASI) announced today that O3^® Regional Oximetry has received FDA clearance for use on neonatal and infant patients (<10 kg). O3 may help clinicians monitor cerebral oxygenation in situations in which peripheral pulse oximetry alone may not be fully indicative of the oxygen in the brain. With this expansion of the O3 platform, the benefits of monitoring with O3 are now available to patients of all ages, from neonates to adults.

O3, which uses near-infrared spectroscopy (NIRS) to monitor the regional hemoglobin oxygen saturation of blood (rSO₂) on both sides of the brain, may be particularly helpful in providing insight into neonatal patient status because neonatal pathology is often brain-related.¹ In neonates, O3 provides reliable measurement with a 3% A_RMS* trending accuracy specification.

O3 sensors are available in three sizes, for adult (≥40 kg), pediatric (≥5 kg and <40 kg) and now infant and neonatal (<10 kg) patients. With its smaller size and flexible design, the neonatal sensor is designed to fit easily and comfortably on the delicate foreheads of tiny patients.

O3 is available as a Masimo Open Connect^® (MOC-9^®) module for the Root^® Patient Monitoring and Connectivity Platform. Root is a powerful, expandable hub that integrates an array of technologies, devices, and systems to provide multimodal monitoring and connectivity solutions. Root’s plug-and-play expansion capabilities allow clinicians to simultaneously monitor with O3 and other measurements, such as SET^® Measure-through Motion and Low Perfusion™ pulse oximetry, providing clinicians with expanded visibility of neonatal oxygenation status. Additional modalities available on Root include advanced rainbow^® noninvasive measurements such as total hemoglobin (SpHb^®), SedLine^® brain function monitoring (available for adult patients), NomoLine^® capnography, and more – all via an easy-to-interpret, customizable display. Using Root in combination with Masimo Patient SafetyNet™ or Iris Gateway™, monitoring data from O3 can be automatically charted in electronic medical records (EMRs).

Joe Kiani, Founder and CEO of Masimo, said, “From our inception, we have been committed to improving outcomes for the youngest and most fragile patients. Our foundational SET^® pulse oximetry was designed with neonates and infants in mind. These patients were not an afterthought. This focus has paid off for these young patients: SET^® pulse oximetry has helped clinicians reduce the incidence of severe retinopathy of prematurity (ROP) in neonates² and improve critical congenital heart disease (CCHD) screening in newborns.³ O3 Regional Oximetry, with its ability to help clinicians accurately track cerebral oxygen saturation, will hopefully have a similar impact. We are happy to be able to bring O3’s advanced capabilities and accuracy to the neonatal patient population.”

*A_RMS accuracy is a statistical calculation of the difference between device measurements and reference measurements. Approximately two-thirds of the device measurements fell within ± A_RMS of the reference measurements in a controlled study.

About Masimo

Masimo (NASDAQ: MASI) is a global medical technology company that develops and produces a wide array of industry-leading monitoring technologies, including innovative measurements, sensors, patient monitors, and automation and connectivity solutions. Our mission is to improve patient outcomes and reduce the cost of care. Masimo SET^® Measure-through Motion and Low Perfusion™ pulse oximetry, introduced in 1995, has been shown in over 100 independent and objective studies to outperform other pulse oximetry technologies.⁴ Masimo SET^® has also been shown to help clinicians reduce severe retinopathy of prematurity in neonates,² improve CCHD screening in newborns,³ and, when used for continuous monitoring with Masimo Patient SafetyNet™ in post-surgical wards, reduce rapid response team activations, ICU transfers, and costs.^5-7Masimo 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 Masimo continues to refine SET^® and in 2018, announced that SpO₂ accuracy on RD SET™ sensors during conditions of motion has been significantly improved, providing clinicians with even greater confidence that the SpO₂ values they rely on accurately reflect a patient’s physiological status. 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^®), RPVi™ (rainbow^® PVi), and Oxygen Reserve Index (ORi™). In 2013, Masimo introduced the Root^® Patient Monitoring and Connectivity Platform, built from the ground up to be as flexible and expandable as possible to facilitate the addition of other Masimo and third-party monitoring technologies; key Masimo additions include Next Generation SedLine^® Brain Function Monitoring, O3^® Regional Oximetry, and ISA™ Capnography with NomoLine^® sampling lines. Masimo’s family of continuous and spot-check monitoring Pulse CO-Oximeters^® includes devices designed for use in a variety of clinical and non-clinical scenarios, including tetherless, wearable technology, such as Radius-7^® and Radius™ PPG, portable devices like Rad-67™, fingertip pulse oximeters like MightySat^® Rx, and devices available for use both in the hospital and at home, such as Rad-97™. Masimo hospital automation and connectivity solutions are centered around the Iris^® platform, and include Iris Gateway™, Patient SafetyNet, Replica™, Halo ION™, UniView™, and Doctella™.
