Device Story

Central station monitor for hospital use; aggregates vital sign and waveform data from ESCORT II bedside monitors and UHF telemetry transmitters. Inputs: patient vital signs/waveforms via proprietary Spread Spectrum LAN or UHF telemetry. Processing: centralized display, storage (up to 24 hours), and alarm management. Output: real-time monitoring, arrhythmia detection, and data retrieval via display or printer. Operated by trained healthcare practitioners. Enhances clinical decision-making through centralized surveillance and configurable cardiac abnormality detection; enables remote monitoring of up to 16 patients.

Clinical Evidence

Bench testing only. Performance testing conducted to verify alarm detection, arrhythmia reporting, and accuracy of vital sign/waveform data. No clinical trials or human subject data presented.

Technological Characteristics

Pentium PC-based system; 16MB RAM; 2GB HDD; MS Windows OS. Connectivity: proprietary Spread Spectrum LAN (902-928 MHz) and UHF telemetry (450-470 MHz). Supports up to 16 patients. Arrhythmia algorithm provided by Zymed Inc. Output via VGA display, thermal array recorder, or LaserJet printer.

Indications for Use

Indicated for centralized surveillance, documentation, and arrhythmia monitoring of patients in a hospital environment. For use by trained healthcare practitioners only.

Regulatory Classification

Identification

The arrhythmia detector and alarm device monitors an electrocardiogram and is designed to produce a visible or audible signal or alarm when atrial or ventricular arrhythmia, such as premature contraction or ventricular fibrillation, occurs.

Special Controls

*Classification.* Class II (special controls). The guidance document entitled “Class II Special Controls Guidance Document: Arrhythmia Detector and Alarm” will serve as the special control. See § 870.1 for the availability of this guidance document.

Trade Name: ESCORT LINK Central Station Monitor Model 20500

Common Name: Central Station Monitor
Classification Name: Monitor, Electrocardiograph Detector and Alarm, Arrhythmia

4. Substantial Equivalence:

The ESCORT LINK Central Station Monitor Model 20500 is substantially equivalent to the ESCORT LINK Central Station Monitor Model 3200.

5. Description of the Device:

The ESCORT LINK Central Station Monitor Model 20500 is a Central Station monitor comprised of a standard VGA Display, a standard Personal Computer Base, and an auxiliary base used to mount the Network communications hardware (i.e. Spread Spectrum transponders and UHF telemetry receivers).

The ESCORT LINK Central Station Monitor Model 20500 can provide the centralized display, storage, and recording (or printing) of patient vital sign and waveform data that is being monitored at ESCORT II 100, 300, or 400 bedside monitors or UHF Telemetry Receivers.

Data accumulated at ESCORT II bedsides is sent via a proprietary Spread Spectrum Local Area Network to the Central Station for display and storage. Data accumulated from any of Medical Data Electronics' analog or digital telemetry transmitters is sent directly to the Central Station on standard UHF telemetry frequencies. The Central Station oversees all communications activity, allowing each system component to pass information without interruption to patient monitoring.

The Central Station can provide alarm detecting and reporting for all vital sign parameters that are available to the Central Station. This alarm response is in addition to alarms that are available at the ESCORT 100, 300, or 400 bedsides. Also, arrhythmia monitoring is available for up to 16 patients at the Central Station to provide the configurable ability to detect and report certain cardiac abnormalities.

The Central Station can provide storage of patient data for up to 24 hours. This includes waveform and vital sign information for all available waveforms and parameter values. The waveform and vital sign data that has been stored in a patient file at the Central Station can be retrieved and viewed on the display or printed out on a Thermal Array recorder or a LaserJet® Printer.

## 6. Intended Use of the Device:

The ESCORT LINK Central Station Monitor Model 20500 is intended to be used to provide centralized surveillance and documentation of patient vital sign data for a variable number of ESCORT Series 100, 300, and 400 bedside monitors and a variable number of UHF telemetry transmitters in the hospital environment.

## 7. Summary of the Technological Characteristics of the New Device Compared to the Predicate Device:

The MDE ESCORT LINK Central Station Monitor Model 20500 is a new Central Station monitor, however, its intended use and method of operation are substantially equivalent to the MDE ESCORT LINK Central Station Monitor Model 3200.

The primary differences between the two devices are summarized in the following table:
