In a Mechanical Ventilator we need to be able to control and vary the pressure and the volume. In the pressure front Daren designed a pitot tube that takes a portion of the airflow that will be used to detect the pressure.

We are considering using some forms of electronic sensors or just using a U tube filled with a liquid to see the difference in an analogue way.

The first 3D prints turned out not leak proof and we are trying to fix that by tweaking the printing parameters.
