DynaMed, a good source for locating the most current guidelines.
Mechanical ventilation: The guidelines seem to be about when to wean, or how to prevent ventilator-associated pneumonia
ARDS: the only one I saw specifically addressing oxygen therapy was from American Association of Respiratory Care (2001).
Professional organization websites:
Society for Critical Care Medicine

Did not locate any guidelines on respiratory failure that mention HFOV
American Association for Respiratory Care
A paper (2007) on the site – http://www.rcjournal.com/contents/09.07/09.07.1224.pdf – indicates that at that time the technique was not included in any AARC guidelines.
Did not locate any other guidelines on the site that address use of HFOV.
AACN Procedure Manual for Critical Care (in EUH Branch Library), 2011. Indicates that there has not been enough evidence to show superiority of HFOV over conventional modes of ventilation in patients with ARDS (p. 278).
