Measurement of O2 (VO2) consumption makes it possible to refine non-invasive assessment of congestive heart failure (CHF). The peak of VO2 during exercise is determined by the maximum values of cardiac output and of the arteriovenous O2 difference. It thus provides semi-quantitative hemodynamic information. In addition, reproducibility of the VO2 peak is quite satisfactory in these patients; it allows them to be classified according to their VO2 peak and permits more objective assessment of therapeutic management. Finally, the anaerobic threshold, when it can be determined, provides the same type of information during sub-maximum exercise.
测量耗氧量(VO2)有助于优化充血性心力衰竭(CHF)的无创评估。运动期间VO2的峰值由心输出量和动静脉氧分压差的最大值决定。因此,它提供了半定量的血流动力学信息。此外,这些患者VO2峰值的可重复性相当令人满意;这使得可以根据VO2峰值对患者进行分类,并能更客观地评估治疗管理。最后,无氧阈值(如果可以确定)在次最大运动期间提供相同类型的信息。
