1. A detector device configured to measure composition of a flow of breathable gas received from a respiratory circuit, the detector device comprising:

  • a housing;

    a flow path engaged with a portion of the housing for the flow of breathable gas having an inlet and an outlet;

    a radiation source within the housing and configured to emit electromagnetic radiation into the flow path;

    a sensor assembly within the housing and configured to receive electromagnetic radiation that has been emitted by the radiation source and has passed through the flow path, the sensor assembly being further configured to generate output signals conveying information related to one or more parameters of the received electromagnetic radiation;

    a pump, at least a portion of which is within the housing, the pump comprising;

    a pump motor; and

    a pump actuator configured to be driven by the pump motor to draw the flow of breathable gas through the flow path; and

    one or more processors housed within an individual compartment within the housing, the one or more processors being configured to execute modules, the modules comprising;

    a source module configured to drive the radiation source;

    a sensor module configured to read the output signals generated by the sensor assembly;

    a pump actuation module configured to drive the pump motor; and

    a pump reading module configured to obtain information related to one or more operating parameters of the pump.
