WebMay 28, 2024 · Figure 2.(A) The Frank Starling curve is shown in blue for 3 different patients with a similar Frank-Starling curve (blue line), yet located at different points along that curve; The x axis shows an induced increase in preload (e.g., fluid bolus) of the same magnitude for all 3 patients (black arrows). As a result of the shape of the curve the change in … WebAnother influence on preload is the functional status of the cardiac valves. If the AV valve regurgitates during systole—that is, allows blood to backflow from the ventricle into the atrium (as with a prolapsed mitral valve)—then the blood volume in the atrium rises not from circulating blood volume but from regurgitated ventricular blood. impresora de red windows 10
