The HFO ventilation setup is made with a standard that works well for keeping pressure in check. The (S)IMV setup is made with a strong design that works for infant and neo-natal ventilation plans. This Humming V setup is used to works well for getting gas moved out and to get gas exchanged the right way. This is used to keep the stroke or tidal volume in check to where it is smaller than the total volume of the total dead space in an area. This uses a smaller pressure change rate in the thoracic cavity to keep the risk that comes with tracheobronchial injury from being worse than it may be. This is also made with less of a consistent change in pressure levels as the system is being used.
