Abstrakt/ Abstract: 
Ciele/ Objectives: The aim of the study was to assess the energy expenditure changes in critically ill patients using continuous indirect calorimetry and compare it with current theoretical models.
Materiál a metodika/ Material and Methods: 20 patients consecutively admitted to the intensive care unit of the Martin University Hospital. Energy expenditure has been monitored continuously during the stay in the unit using indirect calorimetry analysis of every breath by E-sCOVX module in connection with mechanical ventilator GE S 860. Subsequently, patients were divided into two phases: the first phase were patients during the time of full sedation and mechanical ventilation and the second phase were patients during the weaning period until extubation. The monitoring has been continuous with an analysis performed four times a day (24 hours were divided into foru 6 hours intervals, analysis was done in each interval during steady state). Standard requirements for indirect calorimetry were used.
Výsledky/ Results: Energy expenditure during sedation and ventilation has been 1700 – 2000 kcal/kg/day, mean 1824 kcal/day (16 – 21 kcal/kg/day, mean 18 kcal/kg/day) without significant changes. There were no diurnal variations. In weaning, there was steady increase in energy expenditure since day 3 after cessation of sedation up to more than 5000 kcal/day.
Záver/ Conclusions: It seems, that the course of energy expenditure in critically ill should be modified itno to phases: the initial metabolic supression lasting during the period of sedation and mechanical ventilation and the subsequent transition into hypermetabolism during weaning after cessation of sedation.
