Mean systemic pressure is decreased by a decrease in blood volume or by an … WebMay 24, 2024 · Cardiac function may also be affected. Arterial vasodilation decreases the left ventricular afterload, thereby increasing the slope of the Frank–Starling curve. This may explain an increase in cardiac output during the classic “hyperdynamic state” (Fig. 4C). This increase in cardiac output may also be partly linked to the decrease in RVr. WebCompared to control, both Gelofusine® and normal saline significantly and similarly increased mean arterial pressure, stroke volume, cardiac output and central venous pressure in the first hour (P <0.05). Such changes, however, were transient except for the increase in cardiac output seen with Gelofusine®. Normal saline significantly simplified shipping
