Radius PPG™ Tetherless Pulse Oximetry


Featuring Masimo SET® Measure-through Motion and Low Perfusion™ Technology for Continuous Monitoring on the Move

Radius PPG provides industry-leading Masimo SET® pulse oximetry without a cabled connection to a monitor, allowing patients to move wirelessly and comfortably while still being continuously and reliably monitored. Wireless connection to a host device is simple to establish and each Radius PPG can easily pair with multiple devices (maintaining connection to any one device at a time), simplifying transfers between care areas. Automated by Masimo’s connectivity solutions, patient data can be used for remote clinician notification of changes in patient condition and automatically transferred to the hospital EMR.
