"Sepsis is an overwhelming body reaction for any infection and sepsis is a life-threatening condition," Rangaswamy said. "If not diagnosed early and not treated, it can cause significant mortality ...
Norepinephrine raises blood pressure through a vasoconstriction effect, with little effect on stroke volume and heart rate. [5] In some people, the required dose of vasopressor needed to increase the mean arterial pressure can become exceedingly high and it becomes toxic. [ 75 ]
Dopamine may cause rapid heart rate and arrhythmias, and is only recommended in combination with norepinephrine in those with slow heart rate and low risk of arrhythmia. In the initial treatment of low blood pressure in septic shock, the goal of vasopressor treatment is a mean arterial pressure (MAP) of 65 mm Hg. [10]
Severe sepsis, is sepsis that is causing poor organ function, or insufficient blood flow to the body. [4] Insufficient blood flow can manifest as either low blood pressure, high blood lactate, or low urine output. [4]

Hyperdynamic circulation is abnormally increased circulatory volume. Systemic vasodilation and the associated decrease in peripheral vascular resistance results in decreased pulmonary capillary wedge pressure and decreased blood pressure, presenting usually with a collapsing pulse, but sometimes a bounding pulse.
The abdomen, the central nervous system, and the organs (including the lungs) are typically spared, but the extravasation in the extremities is sufficiently massive to cause circulatory shock and compartment syndromes, with a dangerous hypotension (low blood pressure), hemoconcentration (thickening of the blood) and hypoalbuminemia (drop in ...
When the blood vessels suddenly relax, it results in vasodilation. In vasodilatory shock, the blood vessels are too relaxed leading to extreme vasodilation and blood pressure drops and blood flow becomes very low. Without enough blood pressure, blood and oxygen will not be pushed to reach the body's organs.
