What is the typical FiO2 range for ventilated patients to maintain adequate oxygenation?

Explanation:
FiO2 is the fraction of inspired oxygen that the ventilator delivers, and it's adjusted to keep oxygen levels adequate in the blood. In practice, clinicians can set FiO2 from just above room air to the ventilator’s maximum capability. This full range lets them respond to different levels of respiratory failure: some patients can stay adequately oxygenated with a modest increase above ambient, while others may temporarily need the highest oxygen concentration to correct hypoxemia. The goal is to use the lowest FiO2 that maintains satisfactory oxygenation to minimize oxygen toxicity risk, while being prepared to raise it up to the maximum when needed.
