[TVARC] Hams to the Rescue

[k2te at juno.com]

With hospitals in dire need of ventilators and the Government moving at a
glacial pace, here is a cheap-and-dirty (uh, cheap and sanitized) way to
get emergency supplies ASAP.  I think UF needs to team up with the NYC
universities.

Radio Amateurs Team Up to Help University Design Low-Cost Ventilator
Amateur radio volunteers from around the world have volunteered to assist
University of Florida Professor Sam Lampotang and his engineering team in
their quest to rapidly develop an open-source, low-cost patient
ventilator that can be built anywhere from such commonly available
components as PVC pipe and lawn-sprinkler valves. 
The amateur radio volunteers are developing Arduino-based control
software that will set the respiratory rate and other key parameters in
treating critically ill coronavirus victims. 
Multiple volunteers responding to a call for help from Gordon Gibby, MD,
KX4Z, include noted software developer Jack Purdum, W8TEE, and uBITX
transceiver maker Ashhar Farhan, VU2ESE. University of Florida physicians
are working to address the critical legal aspects as the design moves
closer to fruition. The ventilator's valves would precisely time
compressed oxygen flow into patient breathing circuits under Arduino
control, allowing exhausted patients with "stiff" lungs impacted by viral
pneumonia to survive until their body can clear the infection. 
The software design team is also adding simple features such as an LCD
display, encoders to choose parameters, and watchdog safety features.
