Abstract:
PCT No. PCT/EP93/01052 Sec. 371 Date Oct. 31, 1994 Sec. 102(e) Date Oct. 31, 1994 PCT Filed Apr. 30, 1993 PCT Pub. No. WO93/21823 PCT Pub. Date Nov. 11, 1993.A process and a device for determining a patient's circulatory fill status, particularly the global end-diastolic volume of the heart (GEDV), intrathoracic blood volume (ITBV), pulmonary blood volume (PBV), extravascular lung water volume (EVLW), and/or global cardiac function index (CFI) by means of thermo-dilution; with this process intrathoracic thermo-volume (ITTV) and pulmonary thermo-volume (PTV), for example, are obtained and the global end-diastolic volume of the heart (GEDV) is determined from the equation GEDV=ITTV-PTV. The other volumes can be calculated by means of this parameter, which is specific for the fill status of the heart, as well as other species-specific characteristics (a, a', b, b').
