Respiratory diseases affect a large part of world population, especially in developing world. In this invention, we present a breathing support system to provide life-saving support to such patients. The system automates and regulates the use of a bag valve mask (commonly known as an ambu bag). The system uses mechanical actuators, sensors and a smart feedback control mechanism to automate and regulate the operation of the ambu bag to implement core functions of mechanical ventilation for life-saving applications. The system can also be used to provide better breathing support to newborns (e.g. to prevent hypoxia). The system can be used to save hundreds of thousands of lives in the developing world, in emergencies and during transportation globally.
