ScvO2-Centered Optimisation of RED Blood Cell Transfusions

This clinical trial aims to personalise red blood cell transfusion strategies in the crtitically ill patients. The amount of transfusions needs to be minimised in order to prevent adverse events and organ dysfunctions linked to high amounts of red blood cell transfusions.

The researchers aim to investigate the efficacy and safety of measuring the central venous oxygen saturation (ScvO2) (oxygen content in a venous blood sample taken from a central line) to guide clinicians if transfusion is necessary.

The researchers aim to compare the ScvO2 guided transfusion strategy with transfusion based on the clinician's judgment (taking into consideration the patients' comorbidities and actual vital parameters).
