**UPDATE May 10, 2020:** We've redesigned the actuator to make it stronger and more reliable after issues with the gear slipping out of place. The actuator arm's point of contact has been made smaller to improve compression. We've also added designs for our control panel including knobs for the potentiometers used to control compression rate and percentage.
**NOTE:** This is a prototype. It is developed for educational purposes only and has *not* been evaluated by or approved for use by medical professionals.
**Introduction:** This is a low-cost opensource mechanical ventilator. It uses an Arduino controlled 25kg-cm servo driven linear actuator to compress a bag valve mask (the resuscitation bags you see paramedics using to keep patients alive until they reach the hospital).
A video showing the ventilator working can be found here: https://www.youtube.com/watch?v=-b31fEGbNqg
