BVI 3000 Operator’s Manual
Safety and Performance Summary
• The BladderScan
®
BVI 3000 computes the volume of the urinary
bladder based upon twelve, cross-sectional ultrasound images. For
maximum accuracy, be sure to hold the scanhead motionless while
scanning.
• The most accurate measurements are obtained when the patient rests
quietly in the supine position.
• Accuracy is compromised if the user does not obtain an optimal,
repeatable image.
• Errors in usage tend to result in the underestimation of bladder
volume, except in cases where the scanhead is moved during
scanning. In this case, the measurement may overestimate the
patient’s bladder volume.
• The BladderScan BVI 3000 is not intended for use on pregnant
patients.
• The patient being scanned should not have a catheter in his or her
bladder. This could create micro bubbles in the bladder, which affect
the accuracy of the measurement.
• Do not use the BVI 3000 on patients with open skin or wounds in the
suprapubic region.
• Use care when scanning suprapubic and pelvic surgery patients. Scar
tissue, surgical incisions, sutures, and staples can affect ultrasound
transmission and reflection.
• To conserve power, the BladderScan BVI 3000 turns off automatically
when not in use.
• Verathon
®
recommends that new operators first use the BVI 3000 on
patients with moderately full bladders, rather than initially attempting
to locate a bladder with a low volume.
Warning:
There is the possible hazard of explosion if the BVI 3000 is
used in the presence of flammable anesthetics.
