简要总结
The intention of this study is to determine whether the precision of the measure of cardiac output can be optimized by conducting the measurement while the participant is instructed to exhale slowly. This will be compared to measurements done at random to respiration and timed with the participant's spontaneous expiration.

结局指标
主要结局
The observed variance amongst the cardiac output measures
时间窗: 1 hour
The measures will be obtained the first postoperative morning by pulmonary artery catheter thermodilution technique. In total 24 measurements will be done in each patient, i.e 8 measurements in each interventional series described later. The variance observed will create the foundation for calculating the precision of the measures.
