Low venous
Web17 mei 2024 · In other words, in comparison to arteries, venules and veins withstand a much lower pressure from the blood that flows through them. Their walls are considerably thinner and their lumens are correspondingly larger in diameter, allowing more blood to flow with less vessel resistance. Web26 jun. 2014 · LV systolic dysfunction, also usually called “septic cardiomyopathy,” is often present. These have been described to occur in association or alone. Cardiac dysfunction is reversible providing patients recover. Fig. 1 Main mechanisms of cardiac dysfunction, their consequences, and their incidence (in brackets) in severe sepsis and septic shock.
