Here are some notes that explore the application of BVM (Bag-Valve-Mask) kits as simple, low-cost, DIY air pumps. The big idea of this project is that this BVM pump is based on a simple windshield wiper motor (USD $50). Thousands of these motors are already in US (and worldwide) automotive parts distribution network.

This project was inspired by: https://med.umn.edu/covid19Ventilator
