The Pandemic Ventilator

Step 6 Ventilator Running

The Pandemic Ventilator Project

Here is a video of the Pandemic Ventilator running.

I am using an earlier bellows design for my patient simulator. If you wish to test run your own unit you can build a second bellows unit for a lung simulator. No not try it on yourself or anyone else. The patient airline that runs to the simulator is 1/2 inch ID plastic tubing that has been Y ed together at the patient end. You need a regulated compressed air source to run it. It is best if you can get the pressure down to about 10 psi. The higher the inlet pressure, the greater the chance that the bellows will inflate too fast for the upper level switch to detect. If this happens, you blow up your bellows bag. When I initially test ran my unit, I used switches to simulate the bellows mag switches to confirm that the program would function as intended.

I put some wrenches for weights on the bellows and simulator. The weight on the bellows provides the pressure to inflate the patients lungs. The weight on the patient simulator bellows simulated the lung expelling the air. The bellows weight has to be greater than the simulator weight to make it work.
