What is the term for decreasing FiO2?

• A. Augmentation
• B. Reduction
• C. Downregulation
• D. Weaning

Answer: (D)

In oxygen therapy, the term used for lowering the oxygen concentration a patient receives is weaning. It describes the deliberate, gradual tapering of FiO2 as the patient’s condition improves, with careful monitoring of oxygenation to keep SpO2 in the target range and avoid hypoxemia or oxygen toxicity. Weaning reflects a controlled step-down process to determine the smallest FiO2 needed to maintain adequate oxygenation. Other terms don’t fit as well. Increasing oxygen support would be augmentation, which is the opposite of decreasing FiO2. Downregulation is a broader physiological term not specific to stepwise withdrawal of oxygen therapy. Reduction is generic and lacks the clinical sense of a planned, gradual withdrawal process that weaning conveys.
