Transport of gases in high-frequency ventilation

Crit Care Med. 1984 Sep;12(9):708-10. doi: 10.1097/00003246-198409000-00003.


We found that the transport of gases in oscillating gas columns was proportional to oscillation frequency and the square of oscillation amplitude. When these results were applied to high-frequency oscillation and high-frequency jet ventilation in dogs, alveolar ventilation was proportional to frequency and to the square of tidal volume, and inversely proportional to anatomic dead space.
