Radius VSM™

Patient-worn, Continuous, Scalable Vital Signs Monitor (VSM)

The Versatility of a Bedside Monitor in a Wearable Device

Radius VSM monitors a wide range of physiological measurements. Designed to scale up or down with patient acuity, Radius VSM combines the reliability and accuracy of a bedside monitor with the comfort and freedom of a wearable device, allowing for ambulation and movement during continuous monitoring.

Suitable for use across the continuum of care, Radius VSM offers advanced flexibility and is easily scalable to accommodate surges in patient volume and each patient’s level of acuity.

Equip any bed with comprehensive monitoring

Radius VSM monitors a wide range of physiological measurements on a modular platform. Components can be quickly added or removed depending on each patient’s monitoring needs. Without any additional bedside equipment, network infrastructure, or tethered connections, Radius VSM integrates a variety of technologies, modules noninvasive sensors.

Rest Without Distraction

With continuous vital signs monitoring and automatic interval blood pressure measurements, Radius VSM encourages patients to rest comfortably without the disruption of periodic manual measurements.

Information on the Go

Radius VSM provides waveform and parameter trend data on its built-in multi-touch LED display, allowing clinicians to stay informed about patient status while moving about with the patient.

Streamlining Workflows

Streamlining Workflows

When integrated into the Masimo Hospital Automation™ platform, Radius VSM helps simplify clinical workflows by automating patient data transfer to centralized supplemental monitoring systems and documentation in electronic medical records (EMRs).

Mannequin wearing Radius VSM Callouts

  1. Clinically proven Masimo SET® Measure-through Motion and Low Perfusion™ pulse oximetry, including oxygen saturation (SpO2), pulse rate (PR), perfusion index (Pi), pleth variability index (PVi®), and plethysmographic respiration rate (RRp®)
  2. Multiple respiration rate measurements, including measurement from the pleth, from the sound of breathing, and from impedance
  3. Measure-on-inflation noninvasive blood pressure (NIBP), featuring single-patient-use cuffs and automatic intervals (which reduces the need for periodic manual clinician measurement)
  4. Continuous skin temperature measurements with notifications when clinician-specified temperature thresholds are breached
  5. Patient orientation, position, and activity monitoring, alerting clinicians to unsupervised patient movement and possible patient falls, as well as preventable pressure injuries
  6. Electrocardiography (ECG): continuous 6 waveform monitoring available (I, II, III, aVR, aVL, and aVF) with heart rate, respiration rate, and lethal arrhythmia detection, using single patient use, easy-to-apply pre-connected 3-electrode leadwire
  7. rainbow Acoustic Monitoring® which uses an adhesive Respiratory Acoustic Sensor (RAS) to detect the acoustic signals produced by airflow in the upper airway and convert these acoustic patterns into respiration rate, also visualized as a waveform.
