Can ultrasound predict volume responsiveness better than CVP?

by Rick Rutherford, M.D., FAAFP

“What is the patient’s volume status?” This question is commonly asked of medical students rotating through emergency departments and intensive care units across the country. The question is not, however, a simple question and has perplexed experienced clinicians for years. Further, we now know that volume status is not the right question as many who are volume overloaded still respond to fluids and others who appear volume depleted are not helped by additional fluids. Volume responsiveness, a more important clinical question, predicts the ability of fluids to improve clinical parameters such as cardiac output.
