A fiber optic catheter for continuous measurement of central venous oxygen saturation (Scv02> during human cardiopulmonary arrest and shock. When applied in cardiopulmonary arrest (cardiac arrest), the catheter provides therapeutic and prognostic guidelines in the management of a patient in this condition. The catheter also serves as a conduit for fluid and drug infusion and as a sampling port for venous blood. The catheter comprises a body having a first port that exits through a connector body to the computer interface that provides the sending signal and receiving signal which generates central venous oxygen saturation readings. A fiberoptic bundle of afferent and efferent light-conducting fibers transverses the first port to provide signal generation and interpretation of oxygen measured in the blood. A second port is a lumen that traverses and exits at the distal port to allow for pressure measurement and sampling of the venous blood. A third proximal port provides an opening of a lumen that transverses and exits the catheter via a side port spaced from the skin insertion site.
