Ventilator System Reference Design to provide a High Pressure Oxygen to Patients in Assist Control and Pressure Control Modes

Ventilator System Reference Design to provide a portable ventilator used in hallway or non-ICU use cases. This machine can provide high pressure oxygen to patients in assist control and pressure control modes. The assist control mode provides a certain tidal volume of gas to a patient with each inhale. The flow sensor (FS1023) would monitor the gas flow rate at the inhale tube and the tidal volume would be calculated by the MCU using the rate integrated with time. The oxygen valve would be controlled by the MCU and manage the oxygen ratio. The pressure control mode provides a certain pressure to the patient with each inhale. There is one proximal air pressure sensor connected to the mask to monitor the inhale pressure and send that information to the RX23W MCU. The blower, which provides pressure and blows air into the system, is driven by a motor control board that is controlled by the RX23T MCU. It uses I2C communication with the RX23W. A humidifier is added to the system to provide moist gas to the patient
