partial aortic disruption

Answer 3

may have multiple rib fractures

chest pain

upper extremity pulse deficits

harsh systolic murmur

decreased BP / pulse in lower extremities compared to upper

can be caused by severe deceleration

most occur near the ligament arteriosum

Question 4

Cardiac Tamponade

patient in variable degrees of shock or in extremis

decreased arterial and pulse pressures

heart sounds distant

venous pressure elevated (pathognomonic)
