My team making open source turbine-based ventilator. Most of the parts we are using here are used in Drone so that it’s easy to find and use.

Blower(Turbine) that we are using here is:

I will make all the files and design open source as quick as we made.

Technical Goal: Ventilator Mode: PRVC, Pressure Support, Assist Control, BiPAP, CPAP Other: Various Alarm, Touch Screen Interface, Show Realtime Graph, Additional App to See Detail Info.

The Latest Update:

Ventilator enclosure getting ready. We have 3D printed the whole enclosure.

This is the video of the early prototype ventilator. PRVC and CMV-Pressure Support modes are working now. We are working to make it done.

Turbine unit is 3D Printed. Motor is BLDC 1000KV running with 16V. But we have made another turbine which is using another motor running at 24V. Capable of delivering about 50cmH2O pressure.
