Nemo (diveblu3.com/nemo) is the world’s only diving system with an electronic regulator, which would be modified to serve as a respiration detector sensing the breathing of a patient. Minor software modifications can convert Nemo into a machine that behaves like a ventilator with minimal added cost since Nemo already includes a breathing air pump, respiration sensor, and spare microcontroller capacity. If selected, the team projects that BLU3 Ventilator can be produced at a rate of approximately 2,500 units per week within a 2-week startup period and at a fraction of the cost of currently-available ventilators. BLU3 Ventilator can run continuously with access to wall-power or it can be powered with commonly available 12 volt DC batteries.
