Low-Cost Open-Source Ventilator-ish Device or PAPR

  • In the event that COVID-19 hospitalizations exhaust the availability of FDA approved ventilators. This project documents the process of converting a low-cost CPAP (Continuous Positive Airway Pressure) blower into a rudimentary non-invasive pressure support ventilator that could help with breathing during respiratory distress. It’s an evolving project, but in it’s current form, it most aligned with the definition of a non-invasive pressure support BiPAP ventilator.

  • This same project can also be used to create a reasonable low-cost Powered Air Purifying Respirator (PAPR) with filter adapter and mask. PAPRs are effective pieces of Personal Protective Equipment (PPE) that could be helpful to caregivers. PAPRs will also be in extremely short supply and are much less risky and controversial than a DIY ventilator. You may be able to save many more lives by building a PAPR that protects a caregiver than a mediocre ventilator for one patient. Unless you are able to participate in the detailed engineering and medical discussions regarding mitigating the risks of high pressure ventilation, I would highly recommend focusing on the PAPR version of this build.

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 putting information on the internet. There are significant risks associated with using a high pressure BiPAP as a DIY ventilator without medical supervision.
