4/ Deconstructing the PLAx view:
โข The ๐ฝ๐ฟ๐ผ๐ฏ๐ฒ ๐บ๐ฎ๐ฟ๐ธ๐ฒ๐ฟ ๐ถ๐ ๐ผ๐ป ๐๐ต๐ฒ ๐ฅ๐๐๐๐ง, or oriented toward the Aorta/LA relative to LV apex
โข The top of the screen (๐ฅ๐ฉ) ๐ถ๐ ๐ฐ๐น๐ผ๐๐ฒ๐๐ to the probe and
โข (Aorta and MV in view)
โข LA and LV free wall furthest
5/ With those constraints one can determine general PLAx probe location
โข Probe marker ~10 oโclock
โข ~3rd intercostal space
โข Perpendicular to chest

The Apical 3 chamber is a similar view
Deconstructing this is a good exercise to solidify the concept

โข The top of the screen (๐๐ฝ๐ฒ๐ ) ๐ถ๐ ๐ฐ๐น๐ผ๐๐ฒ๐๐ to the probe and
โข Atria are furthest
3/ With those constraints one can determine general ๐๐ฐ๐ probe location
โข Probe marker ~3 oโclock (๐ถ๐ด๐ถ๐ข๐ญ๐ญ๐บ 2:30)
