What is the usual breathing frequency setting range for HFOV in clinical use?

Explanation:
The usual breathing frequency setting range for High-Frequency Oscillatory Ventilation (HFOV) in clinical use is typically 5-15 Hz. This range corresponds to 300-900 breaths per minute, which is necessary for effectively facilitating gas exchange while minimizing lung injury in patients with acute respiratory distress. In HFOV, the high frequency aims to create small tidal volumes that maintain adequate mean airway pressure and provide sufficient ventilation without over-distending the alveoli. The 5-15 Hz frequency range strikes a balance, allowing clinicians to achieve the necessary minute ventilation while maintaining lung protective strategies. A frequency below 5 Hz might not provide adequate ventilation, while frequencies exceeding 15 Hz could increase the risk of lung injury and adverse physiological effects due to excessively high rates that may not correspond with effective gas exchange. Thus, the 5-15 Hz setting is established based on clinical experience and research findings that demonstrate its effectiveness and safety in practice.
