1. A system for ventilating a patient comprising:

  • a bag that is configured to be inflated through an input valve that allows oxygen and/or air to flow into the bag, the bag further configured to be deflated through an output valve that allows the oxygen and/or the air to flow out of the bag;

    an actuator configured to compress the bag to cause the oxygen and/or the air to flow out of the output valve in accordance with prescribed values for one or more respiratory parameter, the one or more respiratory parameter including tidal volume, pressure, volume limit, peak pressure, I;

    E ratio, inspiratory time, and/or breathing rate of the oxygen and/or the air flowing through the output valve to a patient;

    a controller configured to control the position of the actuator and/or the speed at which the actuator moves in accordance with the prescribed values for the one or more respiratory parameter;

    a pressure sensor coupled to the output valve and configured to determine the pressure of the oxygen and/or the air flowing through the output valve, the pressure sensor further configured to send a pressure signal to the controller;

    a flow rate sensor coupled to the output valve and configured to determine the flow rate of the oxygen and/or the air flowing through the output valve, the flow rate sensor further configured to send a flow rate signal to the controller;

    the controller configured to receive the pressure signal and/or the flow rate signal, and to determine whether the output tidal volume, pressure, volume limit, peak pressure, I;

    E ratio, inspiratory time, and/or breathing rate are in accordance with the prescribed values, the controller further configured to adjust the position of the actuator and/or the speed at which the actuator moves so as to adjust the output tidal volume, peak pressure, and/or breathing rate to be in accordance with the prescribed values.
