Additional intraoperative signals are recorded routinely measured and displayed by the anaesthesia machine and the patient monitoring system
Recordings of respiratory and haemodynamic signals in high temporal resolution (sampling rate > 10 Hz): airway flow, volume and pressure (as measured by the anesthesia machine: Dräger Primus) and electrocardiogram and, if available, continuous invasive airway pressure (routine patient monitoring system: Philips MP70). All signals are recorded online using a certified communication port without additional hardware.
Before and at the end of surgery, as well as for the following 5 days, blood samples (10 ml) will be collected. The blood samples are stored at minus 80°C for measurement of:
