1.0 Instrument Description
1.1 Introduction
This section of the service manual provides an overview of the NetGuard System, followed
by more detailed information.
1.2 Overview
The NetGuard System is an ambulatory monitoring system that issues alerts automatically to
clinicians when it recognizes potentially life-threatening cardiac rhythms in monitored
patients. The system monitors patient ECG and heart rate and issues alerts whenever specific
arrhythmias are detected or the measured values deviate from acceptable ranges.
The NetGuard System (shown in FIGURE 1-1) consists of the NetGuard devices, a wireless
infrastructure, a central server, one or more client PCs, and proprietary software running on
the server and client PCs.
The server application collects patient data from the reusable device via ceiling or wall
mounted access points. This allows patients to move within the designated areas of the
hospital. The NetGuard wireless network is based on ZigBee protocol (802.15.4) which
operates in the 2.4 GHz band.
