I've been working on the S-Vent (www.s-vent.life) which is a simple ventilator designed to be produced in areas with limited manufacturing capabilities. It requires no machined, injection moluded or 3D printed parts and could be manufactured in any shed, workshop or field hospital. It uses a medical manual ventilation bag (MVB) which can be hooked up to an oxygen supply if needed and the device provides the input to compress the bag and provide pressurised air/oxygen to the patient.
It can provide the following features:
Variable tidal volume,
Variable cycle time (breaths per minute),
1:2 Inspiration to Expiration ratio (Modifiable),
Presure relief valve (60cm H2O),
Pressure gauge for Inspiration/Expiration pressue monitoring.
Option for PEEP valve and expiration filter
Runs of a 12v supply so can be run off a car battery.

I've been running extended run tests and am trying to source a lung simulator to do validation testing on.
Let me know if you need any more information.
