<unk>  (HFOV) is an alternative method for mechanical ventilation in difficult to oxygenate in critically ill ARDS patients.
Studied in patients with PaO2/FiO2 < 200
Goal is to maintain alveolar recruitment for adequate gas exchange and decrease lung injury/atelectrauma
Low tidal volumes based around mean airway pressures to keep alveoli open

Limits VILI
May improve oxygenation when ECMO not available
No difference or likely to cause harm in adult ARDS patients
Requires heavy sedation
Increase mean airway pressures may result in more hemodynamic instability
High frequency oscillation ventilation

Airway pressure release ventilation
Pediatric jet ventilation
Bag valve mask ventilation
