Detailed Description of the XScribe Stress Testing System

The Baxter Welch Allyn XScribe Cardiac Stress Testing System coordinates patient registration, ECG acquisition, exercise control, physiologic monitoring, event documentation, and final reporting from one workstation. Before a test, the operator selects or creates the patient record, confirms demographic information, chooses the appropriate protocol, and verifies the live ECG signal.

During testing, the system displays multiple ECG leads, heart rate, ST-segment information, exercise stage, and other configured measurements. Operators can label events, record symptoms, review previous ECG segments through full disclosure, and include relevant events in the final report. The exact controls and available screens depend on software version, installed options, and connected equipment.

The workstation is designed for repeated clinical use, with a monitor, computer hardware, acquisition equipment, and optional cart-mounted accessories. Keep the display, keyboard, cart surfaces, and cables clean and organized. Disconnect power when required by the cleaning procedure, then use a compatible non-abrasive disinfectant on external surfaces. Do not spray liquid directly into openings, immerse any component, or use solvents unless the official documentation specifically permits them.

Run a controlled equipment check before patient use. Stop immediately if the treadmill, emergency stop, ECG acquisition, or communication link behaves unexpectedly.

Never use damaged cables, exposed conductors, unapproved accessories, or equipment with fluid intrusion. A qualified biomedical or service professional should perform electrical safety checks, installation changes, and network configuration.

XScribe Troubleshooting Guide

No ECG waveform: Check lead placement, skin preparation, lead-set connection, acquisition-module power, and patient cable condition. Recheck the selected patient and acquisition source.
Noisy or unstable ECG: Ask the patient to relax, reduce movement, improve electrode contact, replace dried electrodes, and route cables away from power and motor cables.
Wireless module will not connect: Confirm battery condition, module pairing, system availability, and distance from the workstation. Restart pairing only according to the approved procedure.
Treadmill does not start: Verify that the treadmill is powered, connected, enabled in the selected protocol, and not latched by its emergency-stop control. Do not bypass safety interlocks.
Blood-pressure data is missing: Check cuff size and placement, monitor connection, device selection, and whether the measurement cycle was initiated correctly.
Printer or report problem: Check paper, printer status, selected printer, network access, and report settings. Export to an approved PDF or XML destination if configured.
Network or EMR transfer failure: Confirm the patient identifier, network connection, interface status, and destination configuration. Contact the site’s IT or biomedical support team.
Unrecognized error message: Record the exact wording, software version, patient context, and steps that preceded the problem. Do not guess at undocumented error codes or alter service settings.

For unresolved problems, remove the system from clinical use when safety or data integrity may be affected. Contact the facility’s biomedical engineering team, authorized Baxter support, or the service organization identified in the local support agreement. Keep the product serial number, software version, configuration, and maintenance records available when requesting assistance.
