Using an ultrasound unit is a complicated process and when learning anything complicated it helps to build up a start-up routine. The actual order in which you do tasks matters less than doing them in the same order consistently, this way, you are less likely to forget a step.

Try the following:

1. Turn on machine
2. Enter patient demographics
3. Select probe
4. Choose preset
5. Apply coupling gel
6. Check orientation of probe (marker toward head or patients right side)
7. Start scanning
8. Optimize image: depth, focus, gain

Each time, every time.
