Low-Cost Open Source Ventilator-ish Device

WARNING/DISCLAIMER: Whenever possible, please seek professional medical care with proper equipment setup by trained individuals. Do not use random information you found on the internet. I am not a medical professional, just a random person on the internet.

In the event that COVID-19 hospitalizations exhaust the availability of FDA approved ventilators. This project attempts to convert a low-cost CPAP (Continuous Positive Airway Pressure) blower into a rudimentary ventilator-ish device that could help with breathing during an acute respiratory distress.

NOTE: As an alternative to a mediocre a ventilator, consider making a PAPR:
