New to site, lost previous description, building medical ventilator in response to COVID19 pandemic, hopefully it will not be needed (especially by me) however I am compelled to create a working unit that can maintain the required parameters of breathing function and contamination control STAT.
I am attempting to keep it as simple as possible while maintaining the ability to modify or add features to the function on the fly. Relay logic , timers and fluid dynamics are what I am working with. As built is an adaptation of the designs to work with the actual stuff I have on hand. I will post pics and docs as I can publish them. Any feed back or helpful recommendations are welcome.
The control works, starting pneumatic circuit construction now. I will publish details as I go.
