: All authors: Karel Roubik, Vaclav Ort, Lenka Horakova and Simon Walzel have a competing interest. The described and experimentally tested principle of inspiratory flow generation was used to construct an emergency lung ventilator (CoroVent) during the COVID-19 pandemic (April 2020–March 2021) financed by the public collection in the Czech Republic and distributed for free to Czech hospitals. Since March 2021, the emergency lung ventilators are not in production nor in sale any longer. All the authors (K.R., V.O., L.H. and S.W.) of this article cooperated on creation and testing of the prototype of the ventilatory unit, but the actual emergency ventilator (not described in this article) distributed to hospitals was developed by a larger team of engineers and experts.
