Evaluation: Nihon Kohden GZ-130 Integrated-Display Telemetry System

February 3, 2022 | Evaluations & Guidance


  • The GZ-130 integrated-display telemetry system is used to monitor patients who are at risk for cardiac events but not acutely ill enough to warrant continuous bedside monitoring. It also offers additional measurements that can be used to monitor conditions like hypoxia and compromised respiratory status.
  • Major components and software features:
    • GZ-130 Vital Signs Telemeter (telemetry transmitter): The patient-worn telemetry transmitter is used to acquire patient data and relay it wirelessly over a local area network using IEEE 802.11a/b/g/n Wi-Fi. The telemetry transmitter is intended for use on adult, pediatric, and neonatal patients to monitor ECG, pulse oximetry (SpO2), and respiration data. The GZ-130 communicates with the central station via wireless access points.
      • The physiologic data can be analyzed, alarmed, stored, and reviewed locally on the display of the monitor.
      • The transmitter is powered interchangeably by either a rechargeable NiMH battery or three AA alkaline batteries and is equipped with a 3.2-inch color touchscreen LCD.
        • Size: 127 × 69 × 30 mm (5 × 2.7 × 1.18 in)
        • Weight: 230 g (8.1 oz) (with batteries)
        • Claimed battery life (with two AA batteries): ≥24 hours (5-lead ECG + SpO2)
      • It is also equipped with software to analyze the ECG and detect high-priority arrhythmias, and it can operate offline as a mini-monitor when communication is lost between the transmitter and the Enterprise Gateway server.
      • Can also pair with Nihon Kohden Life Scope bedside patient monitors
      • Parameters supported:
        • 3/5/6-lead ECG
        • SpO2 (through Nihon Kohden module)
        • Impedance respiration
        • ST/25 arrhythmia + AFib/QT
    • Life Scope CNS-6801 central station—The CNS-6801 allows a centralized view of up to 16 patients on a single display screen and is intended to enable viewing of patient information from the bedside monitors and telemetry transmitters. The CNS-6801 is used to:
      • Admit and discharge patients via an automatically populated list from the hospital's admit/discharge/transfer (ADT) system by using a bar-code scanner or through a patient search feature
      • View near-real-time numeric data, alarm history, full-disclosure waveforms, graphical and tabular trends, and 12-lead and ST analysis
      • Serve as a secondary source of audible and visual alarm signals
      • View discharged patient list, alarm history, and full-disclosure waveforms
    • NK-HiQ Enterprise Gateway server—Windows-based server software used for clinical information management. It is used to:
      • Send patient vitals data and notifications to the patient EMR via an HL7 interface at a hospital-defined time interval. The server can also send a 12-lead ECG report to the facility's cardiac management system.
      • Communicate to third-party secondary notification systems or middleware solutions for clinical notification
      • Connect to the proprietary NK Aware alarm management solution
      • Interface with remote-viewing clients,...
