RUSH stands for “Rapid Ultrasound for Shock and Hypotension”. It is designed to be a quick and easy to perform. The primary indication is undifferentiated hypotension.

Use a curvilinear probe with the abdominal preset exam mode to obtain the windows (Figure 1). The components of the exam can be memorized using the HI-MAP mnemonic (Figure 2).

HI-MAP = Heart IVC Morrison’s pouch Aorta Pneumothorax

Pump (Heart)

  • Assess for pericardial fluid and tamponade (Clip 1)
  • Assess RV function (Note apical sparing and other findings consistent with pulmonary embolus)
  • Assess LV function

IVC (Figure 3, Clip 2)

  • Long axis view
  • Assess IVC diameter
  • Assess IVC diameter change

Morrison’s Pouch/FAST (Figure 4)

  • Assess free fluid within Morrison’s pouch
  • Extend to full FAST when indicated

Abdominal Aorta

  • Transducer below SX
  • Indicator to patient’s right
  • Aorta is circular structure right of the IVC (Figure 5)
  • Scan down to from the celiac branch to the bifurcation
  • Measure upper outer wall to just above vertebral body (Figure 6)
  • Larger than 5 cm is abnormal, increase risk of rupture

Pneumothorax (Figure 7, Clip 3)

  • Bi-lateral 2nd and 4th intercostal space
  • Assess lung sliding
  • Look for lung point
