As many nations struggle to gather resources<\/a>, there is increased pressure on scientists to develop ventilators for COVID-19 patients. This has motivated the development of the Mechanical Ventilator Milano<\/a> (MVM).<\/p>\n The MVM is a reliable and easy to operate ventilator for COVID-19<\/a> patients which can be produced quickly on a large scale, using readily available parts. Designed to work in a pressure-controlled mode, the MVM is safe to use for COVID-19 patients, for whom high pressure may cause further damage to the lungs.<\/p>\n The MVM system connects directly to a line of pressurised oxygen, relying on regulation of the flow to deliver oxygen to the patient. The MVM achieves pressure regulation<\/a> of the end-expiratory cycle by discharging the expiratory flow through a valve which sets the desired minimum positive end-expiratory pressure.<\/p>\n The MVM operations are managed by an electronic system in order to drive the solenoid and proportional values, which is accessible via a touchscreen.<\/p>\n The construction of the MVM is relatively simplistic. Assembly is achievable based on a small set of clear instructions, and the controller software for the MVM is open source and available for customisation by end users.<\/p>\n This new ventilator for COVID-19 patients<\/a> can operate in different modes of ventilation, pressure-controlled ventilation (PCV) and pressure-supported ventilation (PSV), using a simple user interface.<\/p>\nFunctionality of the ventilator<\/h3>\n
