Summary

Cardiac output (CO) is an essential physiological parameter of healthy person or illness. In clinical practices, all methods of measuring the CO(Fick method, thoracic impedance, esophageal echodoppler etc) contain limit. Each method are dangerous or hard to implement. CO is probably determining element of blood transit time and thus the availability of oxygen between the central organs (heart, lung) and the peripheral organs (leg, arms). Our hypothesis is transcutaneous oxymetry mesurement with oxygen inhalation, to cause a transient hyperoxia, can be used to determinate blood transit time between central organs and peripheral organs. This simple method will be non invasive technique.

Detailed description

At admission eligible patients are proposed to participate. Written consent is signed after complete oral and written explanation of the protocol is signed. The time of onset hyperoxia will be compare to usual CO method by cross correlation. The duration of participation for subject is equal to 1 hour.
