High-Precision Ventilator with Compensation Algorithm and Automatic Regulation

CPAP (Continuous Positive Airway Pressure) ventilator is designed based on compensation algorithm and Automatic Regulation. With the use of patient status and system changes in the environment, breathing machine through the compensation algorithm will be dynamically adjusted accordingly. The compensation algorithm, taking into account regional differences in altitude, the pressure, masks and flow loop caused by the pressure of the gas leak and pressure conditioned lack of progressive features. MPC5554 is chosen as the main processor in the system for its high integration and precision. It has several interfaces to communicate with external devices. In the process of designing, some modules are customized. Compared with similar products, the volume and weight are decreased and the cost is reduced.
