Radius-7® The Power of Masimo’s Breakthrough Measurements in a Patient-worn Monitor



With Masimo SET® and rainbow Acoustic Monitoring technology and wireless communication, Radius-7 is designed to allow patient mobility along with continuous monitoring.

Breakthrough measurements

  • > Oxygen saturation (SpO2) and pulse rate monitoring with Masimo SET® Measure-through Motion and Low Perfusion pulse oximetry for reduced false alarms and increased true alarm detection during challenging conditions1, 2
  • > Respiration rate monitoring with rainbow Acoustic Monitoring for increased patient tolerance compared to capnography3

Small, lightweight, and wearable for untethered monitoring and ambulation

  • > Designed to promote greater patient comfort and independence
  • > Reduces the need for nurses to disconnect the monitor each time the patient gets out of bed


Standard wireless communication

  • > Short-range communication to Root® with secured Bluetooth®
  • > Upgradable to WiFi for direct communication throughout the hospital to the Patient SafetyNet™* remote monitoring system

Flexible Functionality

  • > Parameter and waveform views facilitate on-the-spot assessment of patient status
  • > Configurable display shut-off minimizes patient distraction and supports privacy while ambulating
  • > Alarms through Root when in range, or directly on Radius-7 when out of range
  • > Two “hot-swappable,” rechargeable modules (one on Radius-7, one charging in Root) minimizes monitoring interruption
  • > 12-hour battery life facilitates just one module exchange per shift
  • > Single-patient-use armband minimizes cross-contamination risk while ensuring patient comfort
  • > Seamless module pairing with Root to facilitate nursing workflows

Each Radius-7 comes with two rechargeable, “hot-swappable” modules.
