From: The maintenance and monitoring of perioperative blood volume
The Frank–Starling curve showing the relationship between diastolic myocardial tension (preload) and systolic cardiac function (stroke volume). An increase in preload results in a corresponding increase in stroke volume. Using the curve, it is possible to analyze who is a responder and who is a non-responder to fluid therapy. P: preload; SV: stroke volume.
