ABSTRACT:
A method and apparatus for measuring central venous pressure (CVP) is disclosed, along with an improved transducer (50) for measuring CVP in infants. Changes in CVP may also be monitored by employing the method and apparatus of the invention. According to the invention, a transducer is disposed on the neck of a subject (or on the head in the case of infants), and the signal from the transducer is processed to obtain the cardiac component. Thereafter, the vertical distance from the transducer to a reference level is adjusted until the position is located at which the signal transitions between a venous configuration and an arterial or mixed venous-arterial configuration, at which position the vertical distance approximates CVP.
