What causes neurogenic shock?

Loss of blood volume
Damage to blood vessels
Damage to the spinal cord
Cardiac arrest

The correct answer is: Damage to the spinal cord

Neurogenic shock is primarily caused by damage to the spinal cord, particularly in the cervical or upper thoracic regions. This type of shock occurs due to the disruption of the autonomic pathways that regulate vascular tone. When the spinal cord is injured, the body loses sympathetic nervous system activity below the level of the injury, leading to vasodilation and a resultant drop in blood pressure. As a result, despite having an adequate blood volume, the body cannot maintain normal blood pressure and circulation because the blood vessels are not constricting appropriately. Understanding the specific mechanisms of neurogenic shock is crucial for EMTs. It helps in both identification of the condition and in providing the appropriate interventions, such as maintaining spinal immobilization and managing blood pressure support.
