1. An arrangement for analyzing a patient'"'"'s breaths, comprising:

  • a sensor detecting data corresponding to a patient'"'"'s breathing patterns over a plurality of breaths; and

    a processor separating the detected data into data segments, each segment corresponding to an individual breath, the processor analyzing the data segments using a pretrained artificial neural network to classify each breath based on a likelihood that the breath includes an abnormal flow limitation,wherein the classifications include;

    (i) a flow limitation is present;

    (ii) a flow limitation is probably present;

    (iii) a flow limitation is not probably present; and

    (iv) a flow limitation is not present.
