Clinical Question

  • Can emergency medicine physicians performing beside ultrasound measurement of the caval index predict a central venous pressure of less than 8 mmHg in emergency department patients?


  • Bedside ultrasound to measure the caval index can be a useful tool for emergency medicine physicians to predict patients with a central venous pressure of less than 8 mmHg.
  • Specifically collapsibility of greater than 50% with respiration can indicate intravascular volume status.
