1/ Basic #CadiacUS models (color coded / labeled) for Educators or Beginners

At least 2 options when learning any #IMPOCUS – memorize or 𝗰𝗼𝗻𝗰𝗲𝗽𝘁𝘂𝗮𝗹𝗶𝘇𝗲.

Both will get you there but IMO the latter allows for taking next step into advanced imaging…

2/ This is especially true in Cardiac POCUS – 4 basic views, but actually so many more. #ECHOFirst

Firm understanding of anatomy and spatial relationships is key!

➣Note axis of the heart
➣𝗥𝗩 the most 𝗮𝗻𝘁𝗲𝗿𝗶𝗼𝗿 structure
➣𝗟𝗔 the most 𝗽𝗼𝘀𝘁𝗲𝗿𝗶𝗼𝗿

3/ #PLAx is 𝙏𝙃𝙀 view to learn, if any

Major chambers in view
➣LA
➣LV
➣Aorta
➣RV(OT)

4/ Deconstructing the PLAx view:

• The 𝗽𝗿𝗼𝗯𝗲 𝗺𝗮𝗿𝗸𝗲𝗿 𝗶𝘀 𝗼𝗻 𝘁𝗵𝗲 𝗥𝗜𝗚𝗛𝗧, or oriented toward the Aorta/LA relative to LV apex
• The top of the screen (𝗥𝗩) 𝗶𝘀 𝗰𝗹𝗼𝘀𝗲𝘀𝘁 to the probe and
• (Aorta and MV in view)
• LA and LV free wall furthest

5/ With those constraints one can determine general PLAx probe location

• Probe marker ~10 o’clock
• ~3rd intercostal space
• Perpendicular to chest

6/ 𝗧𝗘𝗦𝗧!

The Apical 3 chamber is a similar view

Deconstructing this is a good exercise to solidify the concept
