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.

  • Allows parents and caregivers to hold infants unencumbered by cables and without the risk of tugging on their fragile skin

Enhanced clinician workflow and efficiency

  • Reduces the burden of cable management
  • Eliminates the need to disconnect and reconnect each time patient gets out of bed

Tetherless Radius PPG Pulse Oximetry System at a Glance


The Radius PPG (Photoplethysmography) system is comprised of three parts: (1) a battery-powered single-patient-use wrist-strap, (2) a reusable Bluetooth®-enabled chip, and (3) a wireless receiver. Via Bluetooth, the reusable chip seamlessly pairs with a receiver connected to a host device with integrated Masimo technology to display measurements.
