A new project designed to help address the growing need for ventilator hardware in order to treat the most serious cases of COVID-19 achieved an important milestone today, getting FDA Emergency Use Authorization (EUA) for its units to be used and scaled for production. The hardware, dubbed ‘Spiro Wave,’ is an emergency automated resuscitator that can be produced for under $5,000, and that a team of engineers, doctors and researchers has already begun producing and delivering to care facilities.

The Spiro Wave essentially replicates the functionality of a manual resuscitator, a portable device is typically operated manually to provide ventilation to emergency patients in case of emergency, but it automated the process, while still working with the same types of bags that are typically used with the manual version for easier sourcing of supplies.
