Point of Care Ultrasound - Probe Movements
SWEEPING:
Here we slide the probe along a slug trail of gel, quite crudely, across a wide area of the body. This is often used to ‘window shop’, for structures we can’t see at first. When they snap into view, we can fine-tune movements. Also allows view of larger organs.
ROCKING:
Classic example here is when we get an apical view of the heart. At first, the heart may not be in line with the scan field. We can ‘swing’ it into view, so it appears more square on the screen. Makes parallel measurements more accurate and things less off-axis.
ROTATION:
Great for conversion of the view from short axis, to long axis.  Classic example is obtaining a SAX of a blood vessel, then rotation through 90 degrees to view it in LAX for in plane needling during IV access. We can do the same viewing nerves for blocks.
COMPRESSION:
E.g. applying gentle downward pressure around the umbilical level to displace bowel gas when we are looking at the abdominal aorta. Another; where we apply pressure when scanning vessels to accentuate the pulsatility of the artery/compress the vein.
