PROCEdURE 1. PREPARE FOR THE EXAM
1. Ensure you are familiar with the parts and functions of the BladderScan instrument. For more
information, see the Introduction chapter on page 7.
2. If you are a new BladderScan instrument user, Verathon ® recommends you perform your first exam on a
patient with a moderately full bladder rather than initially attempting to locate and scan a nearly empty
bladder.
3. Check the instrument’s battery icon to ensure the battery has sufficient power.
If the battery icon shows ¼ or less full, replace the battery with a fully charged battery before
proceeding. Place the discharged battery in the battery charger.
4. Ensure that the instrument has been properly cleaned according to the instructions in the chapter
Cleaning & Maintenance on page 52.
5. Be aware of the following conditions that may affect ultrasound transmission and the accuracy of the
exam:
• A catheter in the patient’s bladder. The presence of a catheter may affect the accuracy of the bladder
volume measurement, but the measurement may still be clinically useful (detecting a blocked catheter,
for example).
• Previous suprapubic or pelvic surgery. Scar tissue, surgical incisions, sutures, and staples can affect
ultrasound transmission and reflection.
Do not use the BVI 9400 on:
• Patients with ascites.
• Patients with open skin or wounds in the suprapubic region.
• Pregnant patients.
