The probe is fitted with an orientation marker (OM)
On the image the OM is indicated by a green arrow
The OM facilitates the correct orientation of the probe on the patient

In FATE and adult cardiac ultrasound, the ultrasound image displays the sector with the two radii diverging from the top of the screen
The orientation indicator is on the right side of the screen, and the arch of the sector is displayed towards the bottom of the screen
The ultrasound image on the screen can be turned upside/down or left/right with user controls
A terminology to describe the movement of the probe during scanning is important in order to optimise the image
During the workshop it makes it easier for the supervisor to give instructions without touching the probe which is crucial for the novice in order to achieve practical skill
There are many available descriptions of the method of manipulation of the probe
We recommend using:
1. rotation
2. tilt
3. slide
These movements are applicable to all scanning locations
As a novice – always, only move the probe in one direction at a time
During the workshops the supervisors are encouraged to give instructions with reference to the tail of the transducer and a secondary reference point when appropriate
Examples of secondary reference points:
1. anatomical land marks in relation to the volunteer or patient
2. physical land marks like the bed
3. spatial: left/right – upwards/downwards – medial/lateral
When complying with an instruction, never do any movements in other directions
Vascular access is often easy and straightforward. But from time to time it can be very difficult with multiple failed attempts
Point-of-care ultrasonography most often facilitates rapid and successful vascular access in difficult cases
The advantages of ultrasound guidance for vascular access
Peripheral veins
– Visualisation and use of vessels we cannot see otherwise – i.e. more vessels become available
– More accurate assessment of vein localisation and patency
– Real-time visualisation of needle placement with accurate needle control
– Higher success rate in difficult cases including children
Peripheral arteries
– More accurate assessment of artery localisation and patency
– Higher first time success rate
– Vascular puncture and catheter insertion in localisations not used with traditional blind technique
– Avoiding puncture of the deep side of an artery during needle insertion contrary to traditional blind technique
