Which characteristic is NOT commonly associated with neurogenic shock?

Neurogenic shock is a type of distributive shock caused by the loss of sympathetic tone, typically following a spinal cord injury. The hallmark characteristics of neurogenic shock include bradycardia, hypotension, and widespread vasodilation, which leads to an inability of the body to maintain adequate blood pressure and perfusion to vital organs.

Bradycardia occurs in neurogenic shock due to the loss of sympathetic stimulation to the heart, which normally helps to increase heart rate in response to hypotension. Vasodilatation is a direct consequence of the disruption in sympathetic tone, resulting in the pooling of blood in the periphery and a decrease in systemic vascular resistance. Hypotension is prevalent as a result of both the vasodilatory state and reduced cardiac output driven by bradycardia.

The feature of narrowed pulse pressure is not typically associated with neurogenic shock. In fact, neurogenic shock usually presents with a wide pulse pressure due to the significant drop in systemic vascular resistance coupled with a reduced diastolic pressure, which results from the vasodilation. This distinguishes neurogenic shock from other types of shock, such as hypovolemic or cardiogenic shock, where one might expect a narrowed pulse pressure due to concurrent decreases in
