Markers and Position:

• Marker to the right of the screen (opposite of the other U/S)
• PLAX: marker to the right shoulder, probe between nipples, a little to the left and down
• PSAX: rotate, marker to left shoulder; perpendicular to chest (along MV), tilt to heart base (along aortic valve), tilt to heart apex (papillary muscles)
• A4C: PMI, at left and down of left nipple; marker to left posterior axillary, aim the probe towards right shoulder

Routines:

Proximal Aorta: <3.8cm (usually 2cm)

RV: if dilated, to know if this is acute RV dysfunction or chronic

- old lung problem (COPD/Asthma) = chronic

- if RV apex is actively contracting = acute, likely acute PE (check for DVT)
