• Supine with hips/knees flexed
• At the upper abdomen, halfway between xiphoid & umbilicus, just of midline, press firm & deep to palpate the pulsation of the aorta
• Place your thumb on one side & your index/middle finger on the other side
• Palpate for a prominent lateral expansion of the aorta (aortic aneurysm)
• Alternative technique: Use index/middle fingers of both hands
• Red flag: aortic pulse width >2 cm; back pain with palpation; bruit on auscultation
