A device for the measurement of the central venous blood oxygen saturation rate during a human cardiopulmonary recovery and a clinical shock, and for the treatment of the patient

摘要

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.
