DIAGNOSTICS & TROUBLESHOOTING
IDENTIFYING THE SOURCE OF THE ISSUE
Accuracy and performance issues may be the result of a service issue or caused by a deviation from the
proper instructions for use. Prior to completing any repair or replacement procedures, it is recommended that
you do the following:
• Ensure that the user is following the proper instructions for use, as provided in the latest version of
the Operations & Maintenance Manual, available at verathon.com/product‑documentation.
• When scanning patients, ensure that the user is familiar with the following situations, which may
affect accuracy:
○ Use care when scanning patients who have had suprapubic or pelvic surgery. Scar tissue,
surgical incisions, sutures, and staples can affect ultrasound transmission and accuracy.
○ Do not use the BladderScan instrument on a patient with open skin wounds in the suprapubic
region. The device is not appropriate for use on such patients.
○ Do not use the BladderScan instrument on a patient with ascites.
○ Do not use the BladderScan instrument on a pregnant patient.
○ A catheter in the patient’s bladder may affect the accuracy of the bladder volume
measurement by introducing air into the bladder that blocks the ultrasound signal or by having
the catheter‑retaining balloon interfere with the volume measurement.
○ Obesity may affect ultrasound bladder volume measurements. Lift as much abdominal adipose
tissue out of the way of the instrument as possible. Apply more pressure to the probe to
reduce the amount of adipose tissue through which the ultrasound must pass.
If the issue is not resolved by reviewing the instructions for use, then the issue is likely caused by a service
issue within the console or probe. Complete the following procedures to identify the location of the service
issue.
