I've been looking over the designs being put forward in the various places now, and I cannot understand why people aren't just planning to copy the Manley ventilator. This was the standard ventilator in Europe for decades. It is simple to design, does not even require electricity (mechanical solution driven by air from central compressed air system) so all parts can be sourced locally, and the design has a clinically…
ICU ventilators are surprisingly complicated machines, we've just brought some HAMILTON-C6 machines at work if you want an idea of the top of the line. Ventilating sick COVID patients, or indeed anyone with ARDS, is one of the most challenging things we do in intensive care. Even with high end commercial ventilators, the mortality rate for intubated COVID patients is >70%. I would consider the following a bare-minimu…
Re: Pandemic Ventilator Project
#111None of what you're describing seems particularly hard except the actual ventilation (inspiratory and expiratory), and the detection of patient inhalation (which may need tuning). The rest is just normal programming of an LCD microcontroller.
