Oxygen is recommended for patients with which condition?

• A. Refractory shock & TBI patients
• B. Mild dehydration
• C. Seasonal allergies
• D. Low blood sugar

Answer: (A)

Oxygen is given to maximize oxygen delivery to tissues when the body's ability to supply oxygen is impaired or when the body's demand for oxygen is high. In refractory shock, the circulation isn’t meeting the body's needs, so supplemental oxygen helps raise the amount of oxygen reaching organs during resuscitation. In traumatic brain injury, preventing hypoxemia is critical because low brain oxygen can worsen injury; providing oxygen supports cerebral oxygen delivery and helps reduce secondary brain damage. The other conditions listed don’t typically involve hypoxemia or a clear need for supplemental oxygen—mild dehydration is treated with fluids and electrolytes, seasonal allergies with appropriate meds, and low blood sugar with glucose.
