This project aims to design an emergency ventilator that could be built entirely with widely available off-the-shelf parts from hardware and auto parts stores. The design valued efficiency and simplicity in multiple areas.

• No specialized tools, computer programming, or electronics/manufacturing skills are required.
• The design can be built by one or two people in approximately one day.
• The total cost is roughly $350 in parts. 

In the basic configuration, the design supports a pressure-controlled constant mandatory ventilation mode (PC-CMV), with continuous independent control of positive inspiratory pressure (PIP), positive end-expiratory pressure (PEEP), and an inhale/exhale ratio selection of either 1:1 or 3:1.
