II. Technique

  1. Transducer orientation
    1. Transducer placed in suprasternal notch
    2. Transducer indicator pointed towards 9:00
    3. Align energy inferiorly (towards feet) until arch comes into view
    4. Rotate transducer clockwise until arch is in full view (12:00 to 2:00)
      1. May need to rotate transducer counter-clockwise
  2. Landmarks
    1. Brachiocephalic artery (right), Left Carotid Artery, Left subclavian artery
    2. Aortic arch
    3. Right pulmonary artery
    4. Left atrium

III. Interpretation

  1. Normal aorta diameters (adults)
    1. Proximal aorta: 4 cm
    2. Aortic arch: 3.5 cm
    3. Lower thoracic aorta (and abdominal aorta): 3 cm
