What is the flow rate typically used for an endotracheal tube during ventilation?

When you ventilate through an endotracheal tube, you want an inspiratory flow that is high enough to deliver a full tidal volume quickly, but not so high that it risks barotrauma or wastes gas. The standard practice uses a moderate, middle-range flow—sufficient to fill the lungs effectively on each breath without pushing pressures too high. Flows that are too low won’t provide adequate ventilation through the tube, while flows that are too high can raise peak airway pressures and increase risk of injury. Therefore, the typical mid-range flow rate is the best choice for reliable, safe ventilation through an endotracheal tube.
