In trauma care, what is the target SpO2 range?

• A. Maintain SpO2 at 94% - 98%
• B. Maintain SpO2 at 88% - 92%
• C. Maintain SpO2 at 98% - 100%
• D. Maintain SpO2 at 90% - 95%

Answer: (A)

Maintaining adequate oxygenation is essential in trauma to prevent tissue hypoxia while avoiding potential harm from too much oxygen. Pulse oximetry guides this, and the target for most trauma patients is about 94% to 98%. This range ensures tissues receive sufficient oxygen to support perfusion after injury, without the risks of oxygen toxicity or vasoconstriction that can come with very high oxygen levels. Lower targets like 88%–92% are typically used only for patients with certain chronic lung conditions who may not tolerate higher saturations. Pushing toward 100% offers little extra benefit and can increase risks, so 94%–98% is the best balance in general trauma care.
