Mission
RespiraWorks was formed in response to the COVID-19 crisis to design and build a ventilator with features that specifically target COVID-19 patients and that can be assembled in countries with developing economies. Beyond the pandemic, RespiraWorks will continue to refine its ventilator design and design other medical devices that are difficult for target countries' hospitals to acquire.
Program accomplishments
- Continued collaboration with open source designs, software, test results and integration consulting to interested parties in India and Tunisia. The ventilator designs continue to be refined and have not been used in a patient environment.
