Cardiac Output Measurement in Pediatric Intensive Care Unit by Metabolic Monitor (Fick Method) (PEDIA-FICK-ICU)

Cardiac output measurement is one of the most frequently used haemodynamic parameter used for intensive care unit (ICU) patients. In pediatric ICU, it is often measured with echocardiography that is a non-invasive method but is operator dependant and can't provide continuous monitoring. The goal of this clinical trial is to evaluate the feasibility of cardiac output measurement by Fick's method, non-invasive and allowing continuous monitoring, in comparison to echocardiography in pediatric intensive care unit.
