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
