After seeing the global need for ventilators during the COVID-19 pandemic, Fitbit applied its in-house expertise in advanced sensor development, signal processing, algorithms and hardware design to quickly create Fitbit Flow, an automatic resuscitator inspired by the MIT E-Vent Design Toolbox and based on specifications for Rapidly Manufactured Ventilation Systems. During development and testing, Fitbit conducted extensive simulations and consulted with Oregon Health & Science University emergency medicine clinicians caring for COVID-19 patients & many additional health organizations to receive FDA Emergency Use Authorization (June 2020)
