Background
- Only ED US when probe marker will be pointing to the left (parasternal views)
Technique
- Parasternal Long
- Pointer to the L hip, L 3rd/4th intercostal space adjacent to sternum
- Use to visualize global function and r/o pericardial effusion
- Can evaluate mitral valve, aortic valve, aortic root, LV squeeze
- Parasternal Short
- Pointer to L shoulder, L 3rd/4th intercostal space adjacent to sternum
- Tip: obtain parasternal long view, then rotate probe 90 degrees
- Use to evaluate LV squeeze, R ventricle
- R heart strain = dilated R ventricle
- Apical 4 chamber
- Pointer to Right, usually below nipple
- Use to visualize global function (Left and right ventricle, squeeze)
- Subxyphoid
- Pointer to Right, subxyphoid with probe pointed toward head
- Use liver to as acoustic window to visualize heart
