Brief summary
Measuring hemodynamic parameters in ventilated patients is important yet still complicated to perform. Inert gas rebreathing (IGR) showed promising results when being compared to other invasive as well as non-invasive techniques for the measurement of cardiac output. The aim of our study is to evaluate the feasibility of IGR in ventilated patients.
