Flow entrainment
WebApr 12, 2024 · High-flow delivery systems include Venturi masks and high-flow nasal cannula (HFNC). Entrainment is based on Bernoulli’s principle, which explains what occurs when a stream of gas is pushed through a narrow opening. An air-entrainment system is powered by oxygen (the gas source) with jet orifices on the inside of the device and open … WebJan 12, 2024 · By definition, entrainment is a form of the verb, entrain, which is fluid that is swept along into an existing moving flow. Whenever there is a discussion about fluid dynamics, the Bernoulli’s equation …

WebAs the flow of oxygen passes through the constriction, a negative pressure is created. This causes the ambient air to be entrained and mixed with the oxygen flow (Fig. 6.14). The FiO 2 is dependent on the degree of air entrainment. Less entrainment ensures a higher FiO 2 is delivered. This can be achieved by using smaller entrainment apertures ...
