AbstractThis report discusses initial experiences with the clinical application of continuous cardiac output measurement (OptiQ SvO2/CCO-System). The system was used in 9 intensive care patients suffering either global cardiac insufficiency or systemic inflammatory response syndrome. Continuous cardiac output measurement was recorded during a period of stable blood pressure conditions and compared with the results of the conventional thermodilution method (bolus technique) in these patients. Regression analyses yielded r = 0.523 (r2 = 0.274) for the "urgent" mode, r = 0.943 (r2 = 0.889) for the "fast" mode, r = 0.953 (r2 = 0.907) for the "fast filter" mode and r = 0.990 (r2 = 0.980) for the "normal" mode. Mean differences between the continuous and the bolus technique were calculated as -0.13 +/- 1.81 l/min for the "urgent" mode, -0.42 +/- 0.51 l/min for the "fast" mode, -0.14 +/- 0.48 l/min for the "fast filter" mode and -0.08 +/- 0.19 l/min for the "normal" mode. After a period of two days, the costs of the conventional bolus technique significantly exceeded those of continuous measurement. The expenses for the conventional thermodilution technique are largely determined by the frequency of application and, hence, by the personnel and laboratory costs. In our experience, easy component handling and stable measuring properties make this new method of continuous cardiac output monitoring a valuable method in the diagnose and care of patients who are critically ill.
