Abstract y

Guyton proposed the physiology of venous return and its characteristic curves nearly seven decades ago. This article aims to understand their relevance today—particularly the bedside application—by reviewing the literature. His concepts and experiments have withstood the test of time and profoundly influenced our physiological understanding of both normal and pathological states. Researchers have built upon these principles to further elucidate venous circulation under various clinical conditions. However, unlike the arterial circulation—which lies at the heart of hemodynamic monitoring and shock management—Guyton’s venous return curves have not translated into bedside utility. Central venous pressure (CVP) remains integral to hemodynamic monitoring, though its concept did not emerge from Guyton’s framework. Further studies are warranted to explore the clinical utility of Guyton’s theory at the bedside.
