Hello, this is my first post here, so sorry if i dont follow a rule or something like that. I have a question. Recently i saw that Medtronic liberated the Puritan Benett 560 schemes, and i need help with it. I'm from Argentina and since all this things with COVID-19, i dont have any classes. I'm studying electronics and am currently in my last year. As a kind of "homework" my teacher gave us the mission to create from zero a mechanical respirator, i have to do a report of how i designed it,i have to put all the schemes and circuits, and all that. I downloaded all the RAR files from Medtronic page, and i gave them a look , but i dont know what could i extract from there, my goal with the ventilator is to control the oxygen flow, and one or two of that things that get in the screen. If you know anything that could help me, i'll aprecciate it a lot. Thanks and sorry for my typos.
