The standard tidal volumes used in HFOV are generally between:

In High-Frequency Oscillatory Ventilation (HFOV), the standard tidal volumes typically fall between 3 and 5 mL/kg. This range is chosen to ensure that the ventilation is effective while minimizing potential lung injury. HFOV operates by delivering very small tidal volumes at a high frequency, promoting uniform ventilation and allowing for gas exchange while preventing overdistension of the alveoli.

The selection of tidal volume in this context aims to maintain adequate end-expiratory lung volume and to avoid the risks associated with traditional ventilation methods, where larger tidal volumes may result in barotrauma or volutrauma. In HFOV, smaller tidal volumes help keep airway pressures low and reduce the risk of damage to the lung parenchyma.

Understanding the importance of this tidal volume range is crucial for practitioners utilizing HFOV, as it guides the adjustment of settings to optimize patient outcomes, particularly in scenarios involving conditions like acute respiratory distress syndrome (ARDS).
