And the criteria was: do no harm, don't use any ventilator pieces that are in the supply chain of current ventilators; make sure that we use as few parts as really necessary; make sure that we can get those parts anywhere in the world, because we want people in lots of different countries to be able to make these same things; and then make it easy to use, because if it's not easy to use, people just aren't going to use it.
Y el criterio fue: no hacer daño. No usar piezas que ya se usan para otros respiradores, usar la menor cantidad de piezas posibles, que las piezas se consigan en cualquier parte del mundo porque queremos que las personas de distintos países puedan hacer las mismas cosas, y que sean fáciles de usar, ya que si no es fácil de usar, las personas no lo van a usar.
