Noninvasive cardiac output estimation evaluated from spiroergometric stress test

Abstrakt

The ability to accurately measured cardiac output (CO) is important in clinical medicine. In this paper CO was estimated noninvasively from oxygen uptake during exercise on cycle and treadmill ergometers.

Our pilot study indicated that top level endurance athletes can reach outstanding maximal values of CO at about 40 l/min and stroke volume of 200 ml/beat respectively.
