METHOD AND EQUIPMENT FOR MEASURING DEGREE OF SATURATION OF OXYGEN IN CENTRAL VEIN IN OCCASION OF HUMAN CARDIOPULMONARY ARTIFICIAL REVIVIFICATION AND CLINICAL SHOCK

摘要

PURPOSE: To make diagnosis and prognosis in resuscitation possible, by providing a first lumen to produce readings of central venous oxygen saturation, a first part to be inserted in central vein, and a second part which is sufficiently rigid to support insertion of the first part and to firmly hold the lumen. CONSTITUTION: A first lumen 11 contains a bundle of optical fibers for insertion and retraction, which transmits signals to produce central venous oxygen saturation readings. A first part 21 with a diameter to allow extension of a main body 20 into a central vein, is flexible in insertion and sufficiently rigid against turbulent blood flow to be placed within the vein. A second part 22 firmly retains lumens 11-13 against external pressure in insertion of the main body 20 and a catheter 10. Thus, diagnosis and prognosis management in resuscitation can be performed.
