Researchers looking to produce reliable assessments of cardiovascular state based on arterial blood pressure (ABP) recordings, estimated a key variable (tau, a combination of the resistance and compliance of the arterial system) using ABP measures taken in various locations in the body and compared those to estimates using more invasive measures of aortic flow (AF). In each location (panels A-C), the estimates aligned very closely. Panel D shows that the estimates from the various locations also closely matched each other.
