PROCEdURE 1. PREPARE FOR THE EXAM
Before using a BladderScan device, ensure that you are familiar with its parts. For more information, see the
Introduction chapter.
If you are a new BladderScan device user, Verathon
®
recommends that you perform your first exam on a
patient with a moderately full bladder rather than a nearly empty bladder. A nearly empty bladder can be
more difficult to locate.
1. If the patient meets any of the following restrictions, do not use the device for the exam:
• Fetal patients.
• Pregnant patients.
• Patients with open skin or wounds in the suprapubic region.
• Patients with ascites
2. Ensure that you are aware if the patient has any of the following conditions, which may affect ultrasound
transmission and the accuracy of the exam:
• A catheter in the bladder —The presence of a catheter may affect the accuracy of the bladder volume
measurement, but the measurement may still be clinically useful (example: detecting a blocked catheter).
• Previous suprapubic or pelvic surgery —Scar tissue, surgical incisions, sutures, and staples can
affect ultrasound transmission and reflection.
3. Check the battery icon, and ensure that the battery has sufficient power.
4. Ensure that the device has been properly cleaned according to the instructions in the chapter Cleaning &
Disinfecting on page 22.
PROCEdURE 2. MEASURE BLAddER VOLUME
To ensure the highest degree of accuracy, Verathon recommends that you scan the patient’s bladder at least
three times per exam, in order to ensure the repeatability of your measurements. Repeatability refers to your
ability to center the bladder during each measurement, not your ability to obtain exactly the same bladder
volume measurement each time. Volume measurements should be close, but need not be identical. If you
cannot obtain an optimal, repeatable measurement, the accuracy of the result is compromised.
The device will go into sleep mode 20 minutes after completing the exam. If the device goes to sleep or turns
off due to a low battery before you do one of the following, the exam results will be lost:
• Record a voice annotation
• Manually record the exam results
• Transfer the exam results to Scan Point
®
• Return the device to the charging cradle or docking station
Performing a new exam overwrites any non‑annotated exam results. To ensure that patient data is not
lost, it is recommended that you record a voice annotation with every exam. The device can save up to
10 voice‑annotated exam results. For more information about performing scans, see
Scanning Tips .
1. If the device is in a charging cradle or docking station, remove it. The device turns on automatically.
If the device is not in the charging cradle or docking station and is in sleep mode, press any button. The
device turns on.
