  1. Changes of blood parameters: There is a significant decrease in hemoglobin (Hb), deoxyHb fraction (FHHb) and absolute concentration, while oxygen saturation increased compared to baseline with increasing dilution steps. *< 0.001 for changes in blood parameters of the diluted samples compared to the undiluted arterial (A100) or venous (V100) baseline
