1. An automated oxygen delivery system, comprising:

  • a sensor to measure an amount of oxygen in a bloodstream of a patient;

    a pneumatics subsystem, including;

    an oxygen inlet, an air inlet, a gas mixture outlet, anda gas delivery mechanism, coupled to the oxygen inlet, the air inlet and the gas mixture outlet, to blend oxygen and air to form a gas mixture having a delivered oxygen concentration, and to deliver the gas mixture to the patient; and

    a control subsystem, coupled to the sensor and the pneumatics subsystem, including;

    an input device to receive a desired concentration of oxygen in the bloodstream of the patient,a sensor interface to receive measurement data and status information associated with the measurement data from the sensor,a pneumatics subsystem interface to send commands to, and receive data from, the pneumatics subsystem, anda processor, coupled to the input device, the sensor interface and the pneumatics subsystem interface, to control the delivered oxygen concentration based on the desired oxygen concentration, the measurement data and the status information.
