HFOV

High Frequency Oscillatory Ventilator A device used commonly in larger hospitals for people who's lungs cannot take the stress of a conventional ventilator. The High frequency oscillatory Ventilator delivers 600 to 1200 breaths a minute usually to ventilate the person's lungs, at a very fast rate, so instead of huge lung fulls of air 20 to 100 times a minute causing the lungs to open and close the ventilator only delivers tiny breaths, but at a very fast rate so the lungs are ventilated, and nice and oxygenated, BUT they don't have to be put under all that strain. Its commonly used in the Neonatal Intensive Care Unit for preemature or severly sick infants.
