Ultrasound PPT Flashcards
2 main controls used during ultrasound scanning
gain
depth
what function adjusts the sensitivity of the US probe
gain
what US function adjusts the distance that the probe scans in the tissue
depth….
what US view gives us the pencil point view of the needle, vessel, or nerve
short axis
what US view places the structure in parallel with the US wave and allows more of needle or structure to be seen at one time
long axis
what US view is commonly used commonly to scout vessels
short axis
what US view is used to confirm that the needle/wire/etc is following the correct path
long axis
US approach typically used for nerve block
short axis of the vessel with the needle in long axis
US manipulation limitations for nerve block
limited to shallow and deep adjustments (LAX used - L or R movements would move needle out from US wave/view)
why is SAX (of the needle) not good for nerve blocks?
the tip of the needle is the only thing visible
