How Mechanical Ventilators Work. 1. Air stream (jet stream) is forced through an opening 2. As the jet exits the opening, a localized drop in pressure is seen adjacent to itself drawing ambient air toward the stream. 3. A wall is added to one side of the stream and a separation bubble (vortex) develops.
