Chapter 4: Using the RX‐1 to Monitor a Patient

Notifications

TM
The Rhythm Express RX‐1 device provides status information to the server on each connection. The server can provide
alerts and notification information to the monitoring center staff as to battery status, quality of the ECG signal, and
whether a lead is disconnected. The RX‐1 can also provide an audible notification directly to the patient, when configured
by the server. The audible notification will beep when any of the following conditions are met:

Both ECG leads are disconnected for more than 30 minutes.

The device has detected an Urgent Arrhythmia Event and has been unable to connect with the server within 15
minutes of onset of the event.

The device has been unable to connect with the server for more than 4 hours.

The battery is nearly depleted and needs to be charged immediately.

Preparing the RX-1 Device for a Recording

Preparing a device for a new patient involves the following tasks:

Press the red PTE button for at least 5 seconds until the display shows either Standby or Ready. If the device was
prepared for the next patient, the display will show Ready. If not, it will show Standby.

Confirm that the battery is charged to at least 1 bar on the battery icon. If the battery is not charged to at least 3
bars, a new recording session cannot be initiated.

If the display shows Standby, use the server to select device notification settings. Once the settings are entered on
the server, press the red PTE button for 5 seconds to initiate a connection with the server. Once the settings have
been downloaded to the device, Ready will appear on the display.
NOTE: We strongly suggest that all lead wires be connected to the device by a clinician. Leads are designed to be difficult
to remove and may require the use of a tool (e.g. pliers or forceps).

Connecting the ECG Leads to the Patient

The quality of the ECG signal depends on the contact between the electrode and the patient's skin. We recommend the
use of electrodes 3M 2259 or Ambu BlueSensor VLC, designed for long‐term ambulatory monitoring.

Use only the ECG leads provided by VivaQuant, plug the ECG leads into the device according to the label next to the
connectors as shown below.

The color of each lead wire plugged into the four connectors on the RX‐1 should be as follows:
RL - - - - Green
RA - - - - White
