RUSH Exam or the Rapid Ultrasound in SHock Evaluation
This is a 3 part evaluation focused on cardiovascular etiologies that can be searched for with ultrasound in patients who are in shock.
The Pump- evaluating for the three following things 1. The pericardial sac for effusion and evidence of tamponade; 2. Global LV function; and 3. The relative size of the RV to the LV (increased size of the RV compared to the LV can be a sign of RV strain from PE)
The Tank- evaluating the IVC for intravascular volume status. IVC< 2cm and collapse with inspiratory sniff suggests a CVP< 10 cm H20. FAST should also be performed to evaluate for intra-abdominal and intra-thoracic volume loss and pneumothorax
The Pipes- Arterial- aorta for dissection or aneurysm; Venous- femoral/popliteal veins for DVT (suspect PE)
