## What it is
An open-source project documenting how to convert a low-cost CPAP blower into a rudimentary non-invasive pressure support ventilator or a Powered Air Purifying Respirator (PAPR), created in response to COVID-19 equipment shortages. It includes build guides, engineering discussions, and safety warnings about the risks of DIY ventilators.

## Use cases
- build a low-cost PAPR for caregiver protection
- convert a CPAP blower into a pressure support ventilator
- learn about DIY ventilator design risks
- find emergency ventilator alternatives during shortages
- assemble personal protective equipment from off-the-shelf parts

## When to choose
- you need educational documentation on emergency ventilator/PAPR design
- you want to build a PAPR for PPE purposes
- you are studying low-cost medical device engineering

## When to avoid
- you need an FDA-approved or clinically certified ventilator
- you want actively maintained or supported software
- you lack medical supervision for pressure ventilation use

## Facets
- artifact type: application
- maturity: abandoned
- function: embedded, documentation, simulation
- domain: healthcare, hardware, education
- platform: cross-platform, python
- tags: ventilator, papr, cpap, covid-19, medical-devices, diy-hardware, open-hardware, emergency-response, hardware
