The study´s aim is to evaluate the clinical applicability of the Feature Extraction Technology (FET) during a simulated blood loss scenario.
In an operating theatre blood loss will be simulated in different scenarios. Expired whole blood donations (provided by the German Red Cross, Institute of Transfusions Medicine, Goethe University Frankfurt) will be used. Blood will be diluted by full electrolyte solutions . Sponges and canisters will be prepared with a predetermined amount of blood.
Study participants will estimate total blood loss on sponges and canisters. Study members not knowing the correct amount of prepared blood will measure the blood loss in sponges and canisters by Feature Extraction Technology (FET) and by gravimetric method before and after estimation of the participants.
