概括

在外周静脉外体膜氧化 (VA-ECMO) 模拟中,远程 perfusion 导管 (DPC) 并没有改善四肢 perfusion. 更大的管尺寸和更高的VA-ECMO流量恶化了大腿动脉的血液动力学,否定了DPC的好处.

Blood Flow01:29

Blood Flow

Blood is pumped by the heart into the aorta, the largest artery in the body, and then into increasingly smaller arteries, arterioles, and capillaries. The velocity of blood flow decreases with increased cross-sectional blood vessel area. As blood returns to the heart through venules and veins, its velocity increases. The movement of blood is encouraged by smooth muscle in the vessel walls, the movement of skeletal muscle surrounding the vessels, and one-way valves that prevent backflow.
