Troubleshooting

Equipment Problems

This section identifies some common problems you may experience with the
equipment, lists some possible causes for those problems, and suggests corrective
actions.

Poor Quality ECGs

Poor quality ECGs can be caused by environmental factors, inadequate patient
preparation, or hardware failures related to the acquisition module, leadwires, cables,
or problems with the unit.
If you are receiving ECGs of poor quality, connect the unit to a simulator to obtain an
ECG report. If the resulting report is of poor quality, the problem probably resides
within the unit or connectors and additional troubleshooting is necessary. If the
resulting report is of good quality, the problem is external to the unit, such as
inadequate patient preparation.

ECG Data Noise

If the acquired ECG data displays unacceptable noise levels, do the following:
• Verify proper electrode placement.
• Verify proper electrode application.
Perspiration and dead skin must be removed from the electrode site.
• Check for defective or out-of-date electrodes.
• Check for defective, broken, or disconnected leadwires.
• Check the patient's position.
The patient should remain motionless during the acquisition of a resting ECG.

Missing ACI-TIPI Report

If the ACI-TIPI report does not print as expected, do the following:
• Verify that the ACI-TIPI option is enabled.
• Verify the selected report includes Interpretation.
• Verify the information required for the ACI-TIPI report (age range, gender, chest
pain complaints) was entered.
• Verify the patient was not a pediatric patient (less than 16 years of age).
• Verify the original ECG was acquired by an electrocardiograph with the ACI-TIPI
option.

No BP from External Device

If an external device is not returning the patient's blood pressure to the unit, do the
following:
• Check the protocol used with the device to ensure that blood pressure is supposed
to be returned.
• Check the configuration on the external device.
