What is the primary purpose of oxygen administration in patient assessment?

The primary purpose of oxygen administration in patient assessment is to prevent hypoxia. Hypoxia refers to a deficiency of oxygen in the tissues, which can lead to serious complications if not addressed. When a patient is assessed and shows signs of inadequate oxygenation—such as altered mental status, respiratory distress, or cyanosis—supplying supplemental oxygen becomes crucial.

By administering oxygen, you are directly addressing the need for the body to maintain proper oxygen levels in the blood and tissues, helping to improve cellular metabolism and function. This intervention can be life-saving, especially in emergency situations where oxygen deprivation can quickly lead to serious health issues or death.

While enhancing patient comfort may be a secondary benefit of oxygen therapy, its primary objective remains the prevention of hypoxia to ensure adequate tissue oxygenation throughout the body. Hydration and increasing blood pressure are not direct goals of oxygen administration, making the understanding of hypoxia and its prevention essential for EMTs in patient care.
