2.0 NetGuard Device
The NetGuard patient-worn device (shown in FIGURE 2-2) consists of a wireless, reusable
patient monitor that is attached to the patient, by a disposable adhesive patch, at the
sternum. In the event of a low or high heart rate, ventricular fibrillation, or asystole, the
device transmits a radio alarm signal to alert clinicians that the patient may be experiencing
a significant event. Along with each transmitted alarm, the device transmits 20 seconds of
the patient’s ECG waveform.
2.1 Electrode Placement
The NetGuard device uses 3-electrodes to capture ECG data. The two active and one
reference electrode provide a single, fixed ECG vector.
2.1.1 Placement Instructions
FIGURE 2-1 illustrates the proper positioning of the NetGuard device electrodes. Site
preparation, proper electrode connection, and ECG electrode placement directly impact the
quality of an ECG signal. Optimizing an ECG signal is imperative for accurate monitoring.
This section provides instructions for attaching the elongated adhesive patch just below the
inter-clavicle notch, and a second patch below the left nipple.
