Method and systems are provided for reliable, convenient, self-administered, and cost-effective determination of central venous pressure. The noninvasive method and apparatus use changes in transmural pressure to create detectable changes in peripheral venous vascular volume for the determination of central venous pressure. Transmural pressure changes can be manifested by intravascular or extravascular pressure changes. The system is noninvasive and uses optical measurements of venous volume in the presence of transmural pressure changes. The relationship between the transmural pressure change and the change in vascular venous volume is combined with anatomical measurements to determine the central venous pressure of the subject. Central venous pressure can be used to determine hemodynamic status of the subject to include fluid overload in the heart failure patient.

The invention relates to a method for determining the central systolic blood pressure of a patient, comprising the following steps: determining a peripheral, in particular brachial, blood pressure curve, applying a moving average filter to the blood pressure curve, applying an all-pass filter to the blood pressure curve, determining the central systolic blood pressure as the maximum of the all-pass-filtered and average-filtered blood pressure curves, as well as a device for performing this method.
