Designing a low-cost, open source ventilator with Arduino
March 17th, 2020—
Desperate times call for desperate measures, and while making your own medical equipment isn’t normally advisable, Johnny Lee’e project explores how to turn a CPAP machine into a ventilator.
The idea is that since these machines are basically just blowers controlled by a brushless DC motor, an Arduino Nano equipped with an electonic speed controller could allow it to act as a one.
Such a setup has been shown to provide more than enough pressure for a ventilator used on COVID-19 patients. This device has in no way been evaluated or approved for medical use, but it does provide a starting point for experimentation.
