In trauma management, what SpO2 should be maintained?

• A. 100
• B. 90-95
• C. 88-92
• D. 94-98

Answer: (D)

Maintaining SpO2 in the mid-to-high 90s ensures adequate oxygen delivery to injured tissues without the risks of excessive oxygen. The target range of 94-98% provides sufficient oxygenation while avoiding hyperoxia, which can contribute to damage from oxygen toxicity and perfusion effects. The other options either under-treat (too low) or overshoot (100% oxygen) beyond what most trauma patients need. In most cases, aim for about 94-98% and adjust as patient condition and protocols dictate. If a patient has specific conditions like certain chronic lung diseases, the target may differ, but the standard trauma guideline is the mid-to-high 90s.
