In a trauma patient with a SPO2 of 90% despite oxygen, which action is indicated?

• A. No action needed
• B. Administer aspirin
• C. Initiate or continue ventilation with PPV
• D. Seek alternative diagnosis

Answer: (C)

When a trauma patient is hypoxemic despite supplemental oxygen, the immediate priority is to support breathing. A SpO2 of 90% indicates inadequate oxygenation that oxygen alone isn’t correcting. Providing ventilation with positive pressure ensures each breath delivers an effective tidal volume to the lungs, improving alveolar ventilation and raising oxygen levels. This may involve a bag-valve mask in the field or securing an advanced airway for controlled ventilation, with continuous monitoring of SpO2 and, if available, capnography. Leaving the patient on oxygen alone would not correct the problem, so no action isn’t appropriate. Aspirin isn’t the immediate need in this trauma scenario, as it doesn’t address airway or ventilation and could exacerbate bleeding. While considering other diagnoses is part of assessment, delaying ventilation to pursue alternatives would risk further hypoxia. Therefore, initiating or continuing ventilation with PPV is the appropriate action.
