(57) Abstract :<br />
The central venous sensor assembly (1) comprises a catheler body (2) with several proximal ports (3a, 3b, 3c, 3d). The catheler<br />
portion placed in the vena cava superior (4) is equipped with a proximal flux measurement unit (6), <strong>and</strong> the catheter portion placed in<br />
the vena cava inferior (5) is equipped with a distal flux measurement unit (7) A first input channel (8) supplies a measurement signal<br />
indicative <strong>of</strong> a flux vp to the evaluation unit (10) <strong>from</strong> which the latter calculates a blood flow in me vena cava superior (4). Likewise,<br />
a second input channel (9) supplies a measurement signal indicative <strong>of</strong> a flux vp to the evaluation unit (10) <strong>from</strong> which the latter<br />
calculates a blood flow rate in the vena cava inferior (5). Due to continuity, the sum <strong>of</strong> the flow rates in the upper <strong>and</strong> lower central<br />
veins (4, 5) corresponds to the flow rate through the right heart (11) <strong>and</strong> in the pulmonary artery (12) <strong>and</strong> thus to cardiac output.<br />
