What is an acceptable flow rate range in modern ventilators?

The acceptable flow rate range in modern ventilators is typically between 60-120 L/min. This range is designed to ensure that adequate tidal volumes can be delivered to patients effectively without causing excessive airway resistance or discomfort. Flow rates within this range allow for optimal respiratory support by maintaining sufficient minute ventilation while minimizing the risk of barotrauma and volutrauma to the lungs.

Using a flow rate that is too low may result in inadequate oxygenation and ventilation, while excessively high flow rates can lead to increased work of breathing and potential complications. Therefore, a flow rate of 60-120 L/min provides a balance that supports patient needs while ensuring comfort and safety during mechanical ventilation.
