Suitability of Quark RMR indirect calorimeter to be used with mechanically ventilated patients

The COSMED Quark RMR with the ICU option has been recently assessed to be a suitable indirect calorimeter to be coupled with a mechanical ventilator in an intensive care unit setting.
The study aimed at measuring the influence of the ventilatory settings on the parameters measured by the Quark RMR metabolic monitor. The energy expenditure of 10 mechanically ventilated cardiosurgical patients was estimated at different positive end-expiratory pressure, FiO2 and two different modes of ventilation, with bias flow.

The conclusions show that "the metabolic monitor appears not to be sensitive to the presence of bias flow on act recognition and measurement of expiratory volume; it also shows accurate measurements of FiO2. This agreement guarantees the reliability of the monitor’s measurements when it is coupled with a mechanical ventilator."
