Estimates blood oxygen saturation from capillary blood. Measured in %., From baseline to +6 hours from intervention|Change in blood oxygen partial pressure (PaO2), Blood gas analysis on arterial blood. Measured in kPa., From baseline to +3 hours from intervention|Change in blood oxygen partial pressure (PaO2), Blood gas analysis on arterial blood. Measured in kPa., From baseline to +6 hours from intervention|Change in arterial blood oxygen saturation, Blood gas analysis on arterial blood. Measured in %., From baseline to +3 hours from intervention|Change in arterial blood oxygen saturation, Blood gas analysis on arterial blood. Measured in %., From baseline to +6 hours from intervention|Change in Peripheral Blood Monocyte mitochondrial function, Seahorse X96 analyzer. Analyzes the oxygen consumption rate (OCR), measured in pMoles/min., From baseline to +12 hours from intervention|Change in levels of circulating inflammatory markers, Commercially available panel from the company Olink. Includes 92 biomarkers. Information on the panel can be found here: https://www.olink.com/products/inflammation/#., From baseline to +12 hours from intervention|Change in baroreflex sensitivity, Calculated from continous blood pressure and the distance between the R-waves in a continuous ecg. Baroreflex sensitivity describes how much heart-rate changes when blood pressure changes. Assessment of baroreflex sensitivity is done in a measurement of 5 minutes. The unit is ms/mmHg., From baseline to +12 hours from intervention
