Ventilators
As of November 2020 this challenge was met. The lesson here is that the same
focus if applied to the Return to Life challenge would stop the virus spread
and save lives. As of November 2020 that has not yet happened. All research
has been focused on the Return to Life need.

modified
to hook into hospital oxygen supply . The helmets were originally designed
to run through ventilators, but with the help of Dr. Bhakti Patel, a
pulmonologist at the University of Chicago and her mentor, Dr. John Kress,
the company has modified them to be hooked up to a hospital’s regular
oxygen supply. The team also added a viral filter to avoid exposing others
to COVID-19.

Robertson
Ventilator: Low Tech approach easily sourced and built. University of
Mississippi Medical Center makeshift ventilator with supplies found at a
hardware store. Dr. Charles Robertson, a UMMC pediatric anesthesiologist,
to make the "absolute simplest ventilator we can build with parts available
in any city, you don't need special tools to put together and can be done
quickly as the need arises. Made with a garden hose, lamp timer and electronic
valve, the ventilator, named the Robertson Ventilator, for less than $100,
can be assembled in approximately 20 to 30 minutes, meaning a dedicated team
of four to five could produce nearly 100 in a day if needed.

-
Architecture A: High Tech - that is what is available now but unable to fill
the need (probably all stocks purchased by elite buyers - no gov oversight)
-
Architecture B: Middle Tech - most functions stripped out but electronic
with circuit boards and chips
-
Architecture C: Low Tech - electrical no circuit boards maybe just relays
or power transistors, with a few caps and resistors, and solenoids
-
Architecture D: Mechanical Tech - purely mechanical approach rotating wheel
in an intake / exhaust valve body perhaps via 3D printing
-
Architecture E: Helmet Ventilators - The idea is to use a central "air pump
control subsystem" service multiple patients that are fitted with a plastic
helmet. So perhaps only a few thousand pump subsystems are needed, while
the hundreds of thousands of helmets and hose assemblies that would be needed
are easier to produce in the time that they are needed. This is based on
the bubble helmets seen in Italy.
