The paper deals with development of an artificial lung ventilation The aim of the paper is to present developed ventilator based on bag-valve-mask, which could be used as alternative to mechanical ventilator in critical situations related to COVID-19 At first, we present basic principles of positive pressure ventilation Subsequently, we introduce a requirements to emergency mechanical ventilator in order to be suitable alternative in hospitals as well as in households The mechanical and control design are presented in the next section Finally, we experimentally verify developed ventilator with focus on measured pressure of patient airways The presented results show a potential of developed ventilator to be used at practical level © 2021 IEEE
