How should traumatic brain injury (TBI) patients be oxygenated?

Oxygenating traumatic brain injury (TBI) patients is critical to ensure adequate cerebral oxygenation and prevent secondary brain injury. The use of a non-rebreather mask at 15 liters per minute is the most effective method for delivering high concentrations of supplemental oxygen rapidly. This high flow provides nearly 100% oxygen, which is essential for TBI patients who may be experiencing hypoxia or reduced oxygen levels.

When oxygen levels are compromised in TBI patients, maintaining high oxygen saturations becomes vital, as the brain is highly sensitive to oxygen deprivation. The non-rebreather mask minimizes the patient's exposure to room air, thereby maximizing the delivery of oxygen.

Other options, such as lower flow rates or different delivery devices, do not provide the same quantity or efficiency of oxygen delivery required for TBI patients. For instance, using lower flow rates like those provided by a nasal cannula or a simple face mask may not adequately meet the oxygen needs of a patient with a severe TBI. Likewise, while a ventilation bag can deliver oxygen, it is typically used for patients who are not able to breathe adequately on their own, and the question specifically addresses the oxygenation rather than ventilation support.
