NVIDIA Open-Source Ventilator OP Vent
NVIDIA Chief Scientist Bill Dally created an open-source design for a low-cost, easy-to-assemble mechanical ventilator, called OP Vent. Put simply, it can be built using just $400 of off-the-shelf parts, which is far less compared to the $20,000 that traditional ventilators cost. Between 0.3% – 0.6% of COVID-19 patients develop acute respiratory distress syndrome severe enough to need a mechanical ventilator, so Dally’s goal was to build the simplest possible ventilator.

Dally currently has more than 120 patents under his belt, and his ventilator is built around just two easily sourced, key components – a proportional solenoid valve and a microcontroller to regulate the flow of gas through the valve to the patient. Best of all, the scientist reports that he can bolt the device’s pneumatic components together in mere 5 minutes, and the entire ventilator can be attached to a simple display and slid into a compact Pelican carrying case.

I hope that we don’t get so many people sick that we run out of ventilators. But I want to make sure if we do, something like this is ready,” said Dally.
