  • We present a viable prototype of a simple mechanical ventilator intended as a last resort to ventilate COVID-19 patients. The prototype implements the pressure-controlled continuous mandatory ventilation mode (PC-CMV) with settable breathing rates, inspiration/expiration time ratios and FiO2 modulation. Although safe, the design aims to minimize the use of technical components and those used are common in industry, so its construction may be possible in times of logistical shortage or… CONTINUE READING

    Note that the metallic sound doesn't originate from the device but from the pressure reducer of the oxygen bottle. The clacking sound from the electrovalves can be damped by a
