Supplemental Oxygen and Oxygen Management Practice Test

After activity, the body's need for oxygen drops as metabolic demand returns to resting levels. Because of that, you want to reduce the oxygen supply gradually rather than stopping abruptly or staying on a high concentration. Slowly taper FiO2 in small steps while watching the patient’s oxygen saturation and comfort. If SpO2 remains within the target range on the reduced FiO2, continue the gradual decrease until you reach the pre-activity baseline requirement. If desaturation occurs during the taper, pause the reduction and adjust back to the previous level. This approach keeps oxygenation stable, avoids unnecessary high FiO2, and preserves oxygen equipment.
