- Primary Outcome Measures
Name Time Method The consumption of sevoflurane will be estimated by weighing the vapor before and after the procedure. The consumption of oxygen and air will be collected via the interface of the anesthesia machine. The time and duration until the predefined values for the concentration of oxygen and sevoflurane and any discrepancy will be collected via the interface as well.
- Secondary Outcome Measures
Name Time Method The number of necessary adjustments and the number of requests for an adjustment while using an anesthesia machine without closed loop feedbacks will be recorded. Hemodynamic values as well as peripheral oxygen saturation will be recorded as part of the routine anesthesia documentation.
