Central venous pressure (CVP) is an important hemodynamic parameter, reflecting the patient's volume status. Although some studies of non-invasive evaluation of CVP by echocardiography exist, an exact quantitative method has not been described. ⋯ This new method seems reliable to evaluate non-invasively a hemodynamic parameter that until now has only been measured approximately by this approach.
