The RUSH protocol involves a three-part bedside assessment of:

  • The Pump (heart)
  • The Tank (intravascular volume and free fluid)
  • The Pipes (aorta and large veins)

The HIMAP mnemonic describes which parts of the body to scan:

H Heart


M Morrison’s pouch and FAST

A Aorta

P Pneumothorax

While the whole assessment could be performed using a curvilinear probe, better images are obtained if a phased array probe is used to assess the heart and IVC, and then a curvilinear probe to assess the abdomen, aorta and lung fields.
