SCANNING TIPS
Hold the device steady while scanning. Movement will result in an inaccurate reading.
IMPORTANT
Applying too much pressure when scanning will lead to a “greater than” symbol (>) preceding the bladder
volume measurement. Apply less pressure and re‑scan.
Volume reading will be affected by:
• The presence of scar tissue.
• The presence of a catheter.
• Obese patients—If you are scanning an obese patient, lift as much abdominal adipose tissue out of
the way of the device as possible. Apply more pressure with the device in order to reduce the amount
of adipose tissue through which the ultrasound must pass.
To ensure accurate results, make sure that:
• There are no air gaps between the scanhead and the patient’s skin.
• There are no air bubbles in the ultrasound gel.
• You are holding the device steady while scanning (avoid changing its position, angle, or pressure).
• You are using enough pressure to maintain good skin contact until the scan is complete.
• There is not 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).
