The CoRESCUE AAU Pandemic Ventilator is tested on an artificial lung that simulates various forms of lung disease – including severe pneumonia, as is the case in patients with COVID-19. Using the open source specifications and guidelines available here, a skilled engineer will be able to build and assemble the ventilator. After that it just requires power and supplies of air and oxygen. The AAU Pandemic Ventilator also has an emergency battery feature.
