Final answer:

Hyperventilation after a head injury can lead to a decrease in blood CO2 levels and cerebral vasoconstriction, potentially worsening the outcome by reducing cerebral blood flow and oxygen supply to the brain.

Step-by-step explanation:

Hyperventilation is a condition in which an individual breathes at an abnormally rapid rate, leading to decreased levels of blood carbon dioxide (CO2) and an increase in blood pH, a state known as alkalosis. In the context of head injuries, maintaining adequate CO2 levels is crucial for controlling cerebral blood flow. Hyperventilation can potentially worsen the outcome of head injury casualties by causing cerebral vasoconstriction due to the lowered CO2 levels. This reduction in cerebral blood flow can exacerbate brain injury by decreasing the oxygen and nutrient supply to the injured areas, which may result in increased tissue damage and delayed recovery.
