We are working for Flow-Meter Spa, company active in the design and production of devices for measurement, control and supply of fluids, particularly for applications in the medical field. For Flow-Meter we made a Mobile app for setup EasyVEE® Jet devices for consulting the setup and use data of the EasyVEE® Jet devices: the new "jet" (Venturi) device that works like a high flow generator for CPAP and requires only feeding from a source of oxygen. The use of EasyVEE® Jet devices in combination with a breathing helmet has become the ideal therapeutic choice for treating most patients with severe Covid-19 respiratory syndrome. We can therefore proudly say that we are also making our technological contribution to the fight against Covid-19, given that the use of these devices is widely used precisely to help patients who have to resort to artificial respiration IDE: Visual Studio Technologies: C#, Xamarin.Android, Xamarin.iOS, SQLite.
