In the initial head injury ventilator settings, which FiO2 value was used?

Explanation:
In the initial management of head injury, preventing brain hypoxia is the top priority. Oxygen delivery to the brain depends on both ventilation and FiO2, and the injured brain is particularly vulnerable to low oxygen levels. Starting with a high FiO2 ensures maximal arterial oxygen content and helps keep brain tissue well-oxygenated while the airway, ventilation, and monitoring are being stabilized. Therefore using 100% oxygen (FiO2 = 1.0) is the approach chosen in this scenario. After stabilization, clinicians typically titrate FiO2 down to maintain adequate oxygenation and avoid the risks associated with prolonged hyperoxia.
