HFOV is primarily used for what purpose in mechanical ventilation?

• A. To minimize air leakage in patients
• B. To achieve high tidal volumes quickly
• C. For oscillatory ventilation with low tidal volumes
• D. To ensure maximal flow rates

Answer: (C)

HFOV, or High-Frequency Oscillatory Ventilation, is primarily employed for oscillatory ventilation with low tidal volumes. This mode utilizes rapid respiratory rates and small tidal volumes to improve gas exchange and prevent lung injury associated with traditional mechanical ventilation methods. By delivering minimal volumes of air at a high frequency, HFOV helps to maintain adequate ventilation and oxygenation while minimizing the risk of barotrauma and volutrauma, which are common concerns in patients with compromised lung function. The unique mechanism of oscillatory ventilation allows for better distribution of ventilation throughout the lung tissue, promoting effective gas exchange even in areas of the lung that may be poorly compliant or collapsed. The low tidal volumes ensure that the ventilation provided is gentle, thereby reducing the stress and strain on the alveolar units. In contrast, other methods mentioned may focus on different objectives, such as minimizing air leakage or achieving high tidal volumes quickly, which are generally not the primary purposes of HFOV.
