With an ever increasing number of patients receiving care at home, there is a growing need for high-quality home monitoring and telehealth equipment. Rad-97, in addition to SET® pulse oximetry and advanced parameter monitoring technology through rainbow® noninvasive monitoring, is available with optional integrated blood pressure and capnography measurements. Its innovative communication capabilities allow monitoring data from a variety of third-party Bluetooth®-enabled devices used at home, including thermometers, weight scales, and glucometers, to seamlessly transfer to Rad-97 – and from there to anywhere in the world, in real time. The optional integrated camera allows remote clinicians to interact with patients over live audio and video. Rad-97 brings hospital-grade technology to the home in a single, integrated device that is a monitoring, connectivity, and telecommunications hub.

With its built-in enterprise WiFi capability, Rad-97 has the ability to connect wirelessly from the home to supplemental patient monitoring systems in the hospital, including Masimo Patient SafetyNet™*, allowing clinicians to remotely observe patient status while facilitating automatic data transfer to hospital electronic medical record (EMR) systems. Rad-97 can trend and store data for up to 96 hours.

With its intuitive touchscreen interface, Rad-97 is easy to use for clinicians and non-clinicians alike, and can be easily customized to meet the needs of home users. The device can be configured in Home mode, which streamlines basic utility, giving home users access to applicable settings and messages, while hiding others and locking alarm settings, minimizing the chances of inadvertent interaction.

Joe Kiani, Founder and CEO of Masimo, said, “Rad-97 is well-suited for a variety of care settings, now including home. Facilitated by its powerful connectivity and telehealth capabilities, Rad-97 allows clinicians to remotely interact with patients, as well as monitor their status and spot trends from afar through automated data collection and transfer.”

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,2 and, when used for continuous monitoring with Masimo Patient SafetyNet™* in post-surgical wards, reduce rapid response activations and costs.3,4,5 Masimo SET® is estimated to be used on more than 100 million patients in leading hospitals and other healthcare settings around the world,6 and is the primary pulse oximetry at 17 of the top 20 hospitals listed in the 2017-18 U.S. News and World Report Best Hospitals Honor Roll.7 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.
