Sometimes I see a large pink cross, and other times, a small pink cross. Why?

Large pink cross indicates larger bladder
Often, when you see a small pink cross, indicating very small volumes, you do not get a good view of the bladder and sometimes the pink cross disappears (small bladders will sit behind bowels/organs so you cannot always get a good clear image). In this instance, aim the probe (rays) towards the patient’s feet, and press ‘scan’. If it can see anything, it will give a reading, even if you cannot see the bladder clearly yourself.
Bladder volumes of <50ml are not always easy to see or find.
If after several attempts you are getting 0ml readings, and you are aiming it in the general direction of the bladder, you can be satisfied that there is very little fluid remaining in the bladder.
Have the patient drink, and re-scan in >10minutes. Typically, the adult kidneys will produce approximately 1-2ml/minute (dehydrated patient) or more.
