Figure 2. Scatterplot between PBR and outcomes of microvascular perfusion.
The perfused boundary region (PBR), a measurement for glycocalyx accessibility to red blood cells (RBC), is associated significantly with spatio-temporal aspects of microvascular perfusion variables: A) RBC filling percentage (percentage of time in which a particular vascular segment is perfused) B) Valid microvascular density. In particular, lower PBR (less accessible glycocalyx, thus a better and thicker glycocalyx) is associated with higher RBC filling percentage (temporal perfusion).
