open vented

An open-source ventilator is a disaster-situation ventilator made using a freely licensed (open-source) design, and ideally, freely available components and parts (open-source hardware). Designs, components, and parts may be anywhere from completely reverse-engineered or completely new creations, components may be adaptations of various inexpensive existing products, and special hard-to-find and/or expensive parts may be 3D-printed instead of purchased. As of early 2020, the levels of documentation and testing of open-source ventilators was well below scientific and medical-grade standards.One small, early prototype effort was the Pandemic Ventilator created in 2008 during the resurgence of H5N1 avian influenza that began in 2003, so named "because it is meant to be used as a ventilator of last resort during a possible avian (bird) flu pandemic."
