This application is part of Breath4LifeProject, an opensource initiative distributed under a Creative Commons license led by Anestech Innovation Rising and Hefesto Medtech to assist the worldwide demand for invasive respirators. 
Breath4Life is a mini ventilator for invasive ventilation via positive pressure with an active, portable expiratory phase that does not need electricity for its operation. 
The purpose of this application is to assist in the calculation of the mixture of oxygen flow and compressed air for the Breath4Life mini ventilators.
