Ortho- and antiorthostatic tests (OT, AOT) were performed in critically ill patients to assess cardiovascular system function. Two types of reactions were observed depending on changes in the cardiac index occurring in response to maximum load (transition from the supine -15 degrees into the upright position +15 degrees). In group 1 (58 tests) transition into the upright position caused a decrease in the parameters of the cardiac pump function, while in group 2 (43 (tests) an increase was observed. The results obtained indicate that these tests increase considerably the diagnostic value of central hemodynamic indexes in the assessment of the circulatory function and functional myocardial reserve in critically ill patients.
对重症患者进行了直立和反向直立试验（OT，AOT）以评估心血管系统功能。根据心脏指数随最大负荷（从仰卧-15度转变为直立+15度）的变化观察到两种反应类型。在第1组（58次试验）中，转变为直立姿势导致心脏泵功能参数下降，而在第2组（43次试验）中观察到参数增加。所得结果表明，这些试验显著提高了中心血流动力学指标在评估重症患者循环功能和心肌功能储备方面的诊断价值。
