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.

NVT leads a nation-wide team developing CoroVent ventilator

NVT together with Covid19CZ platform are responsible for development of an emergency mechanical lung ventilator CoroVent for patients with respiratory failure due to Covid-19 disease (corona virus). The project is required by the Czech government. Information about the project are published at

The current status and history of the project:

March 28, 2020
We are working on CoroVent production logistics. The legislative team is working on risk analysis. We are proposing a way of testing each manufactured CoroVent ventilator.

March 27, 2020
In just 18 hours, 12.5 million Czech crowns were collected in the assemblage, thank you for your support!  
Our legislative team is working on all the essential documents for The Electrotechnical Testing Institute (manual, technical documentation or agreement with technical/safety/quality standards).

March 26, 2020
All the proposed solutions and selected parts have been tested. We are testing the first prototypes on the table, very soon the testing of the final prototypes, including electronics and boxing, will begin. The assemblage was launched on the first 100 corovent ventilators on the website

March 25, 2020
In order to accelerate the development of new CoroVent ventilator, we started to use air connection between our lab at FBMI CVUT Kladno (LKKL) and companies of Covid19CZ platform assuring the CoroVent manufacturing. Majority of the important components have been delivered. An interview for Czech Radio – Radiožurnál was published.

Fast delivery using air connection.

March 24, 2020
The algorithm for evaluating tidal volumes, flows, Pmax and PEEP has been implemented in the software. Air transport of the important components throughout the Czech Republic to test the correct function. Other business meetings.

March 23, 2020
The first 3D visualisation of the entire ventilator by MICO Robotic s.r.o. has been made. The website has been launched. 3D printing of some specific components by Prusa3D and testing of their functionality. A control unit was created with the whole software for the ventilator control system.

Touch screen for the ventilator control system.

March 22, 2020
A final list of all the components for the first prototype construction was completed. 
We started to demand the components from suppliers with an emphasis on sufficient quantities. After several consultation with the doctors, a layout of the patient circuit of the ventilator was created. Other Covid-19CZ initiative business meetings (10-20 members).

March 21, 2020
Optimization of the inspiratory system completed. Description of individual components created and provided to the cooperating manufacturers. Consultations in selecting the proper components. Second business meeting (21 members).

March 20, 2020
A final design of the expiratory valve was completed. A complete pneumatic system was finished and its functionality was demonstrated on a mechanical test lung. Definition of other functionalities: control system, driving signals, screen, alarms, etc. Companies contacted under Covid-19CZ initiative, the first business meeting conducted.

March 19, 2020
Expiratory valve design. Several concepts were proposed and analyzed.

March 18, 2020
Karel was woken up by a phone call by Andrej Babiš, the premier :-). The project was approved; the premier of the Czech Republic granted his support to the project and cooperation in obtaining an approval from SUKL (the Czech “FDA-like” organization) once the ventilator is ready. Experimental work stated.

Vašek Ort starting the design of CoronaVent in one of our labs.

March 17, 2020
Several concepts of the ventilator structure were proposed and analyzed. The main concept was selected.

March 16, 2020
The project proposal was submitted to the Czech ministry of Health and the Czech Government. Medical requirements were summarized and discussed.

March 15, 2020
The idea of creating an emergency ventilator was adopted. The preliminary team of experts was created. The first version of the project description was written.


Our NVT team helps to establish Biomedical Engineering profession and education in Cambodia

Our team members Lenka Horakova, MD, Vaclav Ort, MEng, and prof. Karel Roubik, PhD, helps two Cambodian universities (University of Health Sciences and Institute of Technology of Cambodia) to establish a new study program called “Biomedical Engineering”.
The international cooperation is supported by the Czech Republic via the Czech Development Agency. In Phnom Penh, we were supported by the Czech Embassy.
The first students of the new curriculum will start their studies in October 2019; therefore, we have enough things to do through our summer holiday…
