## Success Criteria

Validated Prototype (Looking for partners for testing on Lung Simulators)
Validated Prototype Thanks to [SAMTRONICS](http://www.samtronic.com.br/) This team was super professional and lent us one of the pulmonary simulators that they have available at the company.

## Current Status

## Modules

- **Electronic Controller** Status `Testing`
- **Mechanical Motor** Status `Implementing`
- **Ventilator** Status: `Validation`
- **Humidifier** Status: `Design`
- **Filtering** Status `Implementing`
- **Peep Valve** Status: `Adopted` - Thanks to [ProjectOpenAir](https://www.youtube.com/watch?v=HEfCRcew_pk)
- **Breathing tube** Status: `Testing`
​
- **Electronic Controller** Status `Use if Available` on the Spartan Model only Reles, Diodes and Switches
- **Mechanical Motor** Status `Mandatory` we recomend Bosch VW motor by the availability and stamina delivered
- **Humidifier** Status: `Deprecated` we are now using HME filter widly available.
- **Bellow Ventilator** Status `Recommended` We don't belive Ambu-bags are reliable as a Mission Critical Device. Use a Tire.
- **Filtering** Status `Adopted` Is the only way we managed to reduce contamination on the outake system
- **Peep Valve** Status: `Adopted` - Pressure control with pipe height adjustment
- **Over Pressure Valve** Status `Adopted` - This is the Garantee that personal using this machine won't kill someone
- **Diverter Valve** Status `Adopted` - Please use it on the Vertical Position THIS IS MANDATORY to be reliable
- **O2 mixing system** Status `Researching & Testing`
