Experimental Investigation of the Applicability of the Stress‐Based and Strain‐Based Hemolysis Models for Short‐Term Stress Peaks Typical for Rotary Blood Pumps
The results suggest that the stress-based hemolysis model is not appropriate for the applied short-term stress peaks. The strain-based model, which considers the deformation of the RBCs over time, appears to be more appropriate for this type of flow. This implies a similar relationship for RBPs, where these short-term stress peaks are typical.
