    I’m from Guatemala. We are deeply concerned on the exponential growth of this pandemic and want to recieve as much information as posible to start prototyping the ventilator, and possibly provide an option for the people affected.


    We are part of a group of entrepreneurs in the Amazon Region in Brazil who are endevouring what is possibles to bring ideas and new low-cost technology for assembling or producing ventilator to help hospitals and ambulances during the coronvirus fight. We need your help and ideas so we can stay put and firm during this illness.

    Dear Researchers,

    I live in San Diego, CA and basically from India. I’m very interested in building this product as soon as the working prototype is available. My interest is to build and make it available on emergency situation. I can get the respective Government permissions and connect with manufacturing units on not-for-profit basis. All the best with your research.

    Hi All: Just registered today here, as this E-Vent web site was recommended to me. I have designed a number of ICs and integrated SOCs. In process of becoming familiar with all the specifications for ventilators.
    I have an immediate comment/question on the power supply. It is specified as 12V and 5A nominal (typ). Later, the description mentions 15A spikes/surges. If the 15A “events” are occurring, are observable, or are expected during this ventilator’s normal operation do please upgrade the power supply requirement from [12V and 5A nominal] to [12V and 15A nominal].

    From the reliability point of view it also makes sense to have a single 12V & 15A typ power supply (one component) than having a 12V & 5A typ supply plus an added capacitor to handle 15A spikes (two components) / or a 12V additional battery.

    For redundancy purposes, yes, an additional 12V battery makes sense as a stand-by power-failure backup. I would recommend that the single main power supply be capable to handle well the 15A load spikes in a repetitive manner.

      spikes are not power drawn but the surge due to the motor being stopped suddenly. hence it would be a reverse power surge that needs to be suppressed. Also for starting toque few capacitors can provide the necessary boost. no point in increasing the cost of the power supply. also as per the power calculations given we only require around 26w of power. 60w power input is already over compensated.

        Hi Mohit: in common practice, to suppress the 15A spike generated each time the motor turns off, would like to mention that “Flyback diodes are commonly used when inductive loads are switched off by semiconductor devices: in relay drivers, H-bridge motor drivers, and so on” (Wikipedia). A capacitor is not necessarily needed in conjunction with the power supply when the motor turns off.
        Understood that these 15A spikes are not drawn from the power supply, so the power supply itself can be defined as 12V and 5A typical/max (we are not doing any fancy inductor-stored energy-recovery).
        Still this means 60W. Where can I find info on the “around 26W power calculation given” please?

        Capacitors are used at times for motor startup. So if my updated understanding is correct, we have
        A) no added capacitors are used in conjunction with the power supply, and
        B) capacitors are used in conjunction with the motor turning ON
        C) motor turning OFF generates 15A spikes that need to be suppressed

    Dear Researchers
    Iam from South Africa,in the past have worked with Prof Neil from MIT collabotating with CSIR rapid deployment of fablabs,would like to know is the package going to be available on Open Source..as the is infrastructure for mass production in place for such ventilators as they are about to be medical focal point in South Africa

    hello, I am from Mexico and worry as you about the critical issue of ventilators with no previous experience in this field but capable of organizing a task to set up a production line. Please tell me what is necessary to do it. ¿wherecan look for specifications, drawings, guidance for assembly? thank you very much and many thanks to the people have done this possible. My email is aselem@gmail.com and cel and WhatsApp is +52 1 55 15 574577

      Que tal, Sergio aquí, estamos evaluando la adaptación de este diseño a la cadena de suministro mexicana. Unir manos esfuerzos nos ayudara. Ya estamos en contacto con la cámara de comercio de Sinaloa y organizando revisiones con especialistas. Si alguien está trabajando en entre proyecto o tiene información favor de contactarme sergio@aquaexploracion.mx

      James – based on the latest guidance from the FDA – what exactly is needed for approval in the US? What testing, documentation, etc? I think we would all appreciate expertise in understanding this, especially from an engineering, then subsequently manufacturing perspective. Clearly there will be no “1” device. Thanks. Feel free to reach out directly, also, I’ve asked our regulatory team the same question.

    Hello, I am a Vietnamese living in Japan and I am currently staying home isolated to prevent the plague. I believe I can try and successfully make the ventilator with the amount of resources available here. Please help me.


    Hello, I would like to receive information on the design plans. I am from HONDURAS and my country is very poor. I would like to help my city. There are more than half a million people and there are only two mechanical fans. I hope your help.

      Please contact UNAH. Now they have designs for ventilators and students are frantically working to get them done.
      Por favor contáctate con la UNAH. Ya ellos tienen diseños de ventiladores clínicos. Si puedes ayudar, es de unirse con ellos.
      Los estudiantes han estado trabajando en eso ya. Unámonos todos en esta lucha.

    Medtronic PB560 design, manuals, and specifications info (WEB site) can be accessed (after a simple and free on-line registration) at:

    “Medtronic is mobilizing to fight the COVID-19 pandemic — and we’re inviting innovators everywhere to join us. Currently, there is a shortage of respirators and ventilators around the world. As recently announced, Medtronic is responding to this crisis by making the design files for the PB560 ventilator system available to the public. Our hope is that manufacturers and engineers will use this intellectual property to inspire their own potentially lifesaving innovations.”

    Saludos desde Chile, necesito saber si puedo realizar este proyecto, con fines de ayuda a mis compatriotas ya que en algún momento serán de much utilidad, y si no en otro lugar del mundo, entonces necesito saber ver, estudiar este proyecto juntarme con la gente y los recursos y desarrollarlo. en nombre de la humanidad y los seres que amo. He desarrollado una impresora 3d con Arduinos y esto parece relativamente realizable. así que ayuda por favor los planos videos tuturiales, si me otorgan eso juro lo realizo

    I need information, how built a vent because in my country, we dont have nothing.
    Necesito planos de fabricación con fines de ayuda, en mi país solo hay alrededor de 100 ventiladores en los hospitales y quisiera poder fabricar para ver como puedo ayudar

    Dear MIT Responsibles and researchers,

    I am interested in getting complete informartion in order to manufacture Medical Ventilators to my country (Peru) in order to help facing this terrible pandemic in our country. We are specialized in thermal equipments and ventilators for industrial purposes but we will be able to help developing this critical equipment.
    Looking forward to hearing from you.

    I am a student of mechanical engineer from Nigeria. The current cases of the covid-19 is fast rising and the country needs more ventilator. I would like to get more information about the E-vent so that I can help the people of my country in my own little way.

    I read in MIT review that the MIT team is having conversations with the FDA on getting an emergency approval for this design. Can you please tell us what the status is of this discussion? Any advice for others in the US who want to make these devices? Thanks.

    My company is interested in putting together a prototype of the most current design available of this e-ventilator for evaluation, testing, improvements as needed and setting up a production line of these units. How do we go about getting drawings and parts lists to start the process. I would appreciate a prompt reply.

    Hi I live in Chile, in extreme zone ( Patagonia) in this zone there is a one hospital and
    there are not enough mechanical fans in my area. My husband is mechanical enginering, he wants to built a ventilator to help the people. I you may send me the plans to build it ?

    Kind regards
