What is a RUSH Exam? (this is useful and we should discuss but not in trauma section)

Rapid Ultrasound for Shock and Hypotension

Indication: Used in the setting of undifferentiated shock to identify its common causes

Evaluates for:

  • Pump failure: Myocardic ischemia, arrhythmias, tamponade, valvular insufficiency, pulmonary embolism
  • Pipe failure: shock from sepsis, anaphylaxis, or neurologic causes
  • Tank failure: hemorrhage, hypovolemia, tamponade, or tension pneumothorax

Approach (See links to other exams on the blog):

  • Lung exam – evaluate for pneumothorax
  • Cardiac exam – evaluate for effusion, tamponade, RV strain, and LV function
  • FAST exam – evaluate for intraperitoneal free fluid
  • AAA exam
  • IVC exam – check patient volume status
