	A bedside ultrasound was conducted to assess for AAA with clinical indications of hypotension and lower back pain. The aorta was assessed at 4 locations in the transverse plane – proximal, mid, distal, and aortic bifurcation. Additionally, the distal aorta was viewed in the sagittal plane. No sonographic evidence of ~~DVT~~ at these sites.		A bedside ultrasound was conducted to assess for AAA with clinical indications of hypotension and lower back pain.
