Non-conventional Ventilatory Team (NVT)

Our research is aimed at all aspects of artificial lung ventilation: theoretical analyses, modeling, design of respiratory care equipment, animal ventilatory experiments, clinical trials and education in respiratory care. We are focused especially on High Frequency Oscillatory Ventilation (HFOV), heliox and Electrical Impedance Tomography in respiratory care. NVT is based at Czech Technical University in Prague, Faculty of Biomedical Engineering.

Innovators 2020

A professor, Karel Roubík, from the Faculty of Biomedical Engineering at the Czech Technical University began in the 1990s in Podolí, Prague, at the Institute for the care of Mother and Child, where he designed unconventional ventilatory techniques. This came in handy last spring 2020 when there was a threat of an acute shortage of ventilators in hospitals. And so he prepared a prototype with his small team, for which tens of millions of crowns were raised in record time. The CoroVent project created several hundred ventilators that were not needed in hospitals in the end, but the event showed how efficient, fast and innovative the local technology community can be.
