Evaluation: Philips IntelliVue Cableless Measurement with IntelliVue Guardian Software for Continuous Vital Signs Monitoring

June 29, 2016 | Evaluations & Guidance


  • The Philips IntelliVue Cableless Measurement with Guardian software continuously monitors patient vital signs through use of one or more "pods" worn by adult patients in non-ICU care settings. Three different pods measure parameters including pulse rate, respiration rate, intermittent NIBP, SpO2, and patient posture and activity. The Guardian system analyzes, interprets, and applies a hospital-customized Guardian EWS algorithm to vital signs data to offer trends and visual notifications, for the purpose of detecting and notifying clinicians of signs of early patient deterioration.
  • The system also allows manual entry of other parameters such as level of consciousness/alertness, presence of sepsis, pain score, and temperature. These parameters are also used by the EWS algorithms when available.
  • Major device components and software features:
    • Cableless pods. Three units worn by the patient and connected wirelessly via short-range radio (2.4 GHz ISM IEEE 802.15.4) to a spot-check monitor1placed at the point of care. The pods can also connect via short-range radio to an in-room hotspot. The spot-check monitor or hotspot then connects to a central station workstation running Guardian software via 802.11 a/b/g wireless.
      • CL SpO2 pod—measures pulse rate and SpO2 using the FAST-SpO2 algorithm. Consists of a small, battery-operated reusable device mounted in a disposable cradle attached to the patient's wrist, and a disposable proprietary finger sensor.
      • CL NBP pod—measures NIBP and pulse rate (if the SpO2 pod is not in use) through the oscillometric method during deflation. Consists of a reusable battery-operated device mounted in a disposable cradle attached to the patient's arm, and a disposable proprietary or generic (bayonet connector) NIBP cuff. Typically worn on the arm not wearing the SpO2 pod. An alternative approach is to connect a long extension hose to the cuff and place the NBP pod elsewhere (e.g., pocket).
      • CL RR pod—measures respiration rate, pulse rate (if the SpO2 and NBP pods are not in use), and patient posture and activity. Consists of a reusable battery-operated device mounted on a proprietary disposable adhesive patch. Philips recommends mounting the RR pod on the left costal arch.
    • Spot-check monitor. The MP5SC multiparameter patient monitor; it is compatible with the Cableless pods. This monitor receives patient data from the Cableless pods, spot-check probes (e.g., temperature), and manual entry (e.g., level of consciousness/alertness, pain score, presence of sepsis), interprets data with onboard algorithms including EWS, and transmits patient data to the Guardian software.
    • Hotspot. A small plug-in device, typically placed one per patient room or placed in areas where mobile patients regularly pass by or spend time (e.g., care area hallways). Receives patient data from Cableless pods within a 10 m line of sight and transmits it to the Guardian software.
    • IntelliVue Guardian software. Windows-based workstation for clinical information management. Can be installed on a facility-supplied Windows-based server or PC. Receives patient data from spot-check monitors or hotspots and:
      • Admits and discharges patients
      • Connects to the admission/discharge/transfer feed (automatic or manual) to enable patient ID and demographics
      • Connects to laboratory information systems to pull data if required by early warning scoring protocol (e.g., white blood cell count for a sepsis protocol)
      • Stores patient information
      • Provides trends, both graphical and tabular, for SpO2, temperature, respiration rate, NIBP, pulse rate, and early warning score
      • Applies EWS algorithm to provide visual notification to clinicians of potential patient deterioration
      • Communicates to secondary alarm notification systems or middleware for clinician notification
      • Sends patient vitals data and alarms to patient electronic medical record (EMR) via an HL7 (Health Level 7) interface
      • Allows clinicians to enable manual patient measurements on individual pods (e.g., inflate an NIBP cuff)
  • The device is typically used in:
    • Medical-surgical floors
    • Emergency departments
    • Intermediate care floors
