The Macgyvilator disaster ventilator Mk2! (3/25/2020) Now with validated respiratory parameters.

Описание: In response to feedback and suggestions from Mk1 (thanks everyone!), I made some changes and threw together the Macgyvilator disaster "ventilator" Mk2. It's more capable than Mk1, and more importantly, I've validated its output with a respiratory flow meter. As built, it delivers a max tidal volume of ~460 mL and an I:E ratio of ~1:2.7, which is a helpful output according to my respiratory and critical care colleagues.

To be clear, this is not a substitute for a real ventilator! This is mandatory ventilation only; the lack of a breath trigger is probably its biggest weakness. It's one step above prolonged hand-bagging, and it's meant to be a base for further tweaking/building.
