Nvidia [https://www.nvidia.com/en-in/] Chief Scientist Bill Dally has released
an open-source ventilator hardware design he developed in order to address the
shortage resulting from the global coronavirus pandemic. The mechanical
ventilator design developed by Dally can be assembled quickly, using
off-the-shelf parts with a total cost of around $400 ? making it an accessible
and affordable alternative to traditional, dedicated ventilators, which can cost
$20,000 or more.

The design created by Dally strives for simplicity, and basically includes just
two central components ?a??solenoid valve and a micro-controller. The design is
called the OP-Vent [http://op-vent.stanford.edu/], and in this video
[https://youtu.be/vAR43ow1w0Q]you can see how bare-bones it is in terms of
hardware compared to existing alternatives, including some of the other more
complex emergency-use ventilator designs developed in response to COVID-19.

Dally?s design, which was developed using input from mechanical engineers and
doctors, including Dr. Andrew Moore, a chief resident atStanford University
[https://crunchbase.com/organization/stanford-university]and Dr. Bryant Lin, a
medical devices expert and company co-founder, can be assembled in as little as
five minutes, and is small enough to fit in a Pelican case for easy
transportation and potability. It also employs fewer parts and uses less energy
than similarly simple designs that adapt the manual breather bags used by
paramedics in emergency response.

Next up for the design is getting it cleared by the FDA under the agency?s
Emergency Use Authorization program for COVID-19 equipment, and then seeking
manufacturing partners to pursue large-scale manufacturing.
