Abstract
There is provided a computer-implemented device comprising a processor, a machine readable medium storing instructions, the instructions when executed by the processor for configuring the device for: receiving an airflow and volume signal from at least one airflow and volume sensor for a plurality of patients; digitizing the signal to a digital signal and segmenting the signal using a sliding window to extract a plurality of features from the digital signal comprising: peak-to-peak amplitude, root mean square, integral of the absolute values, zero-crossing rate, standard deviation of a first derivative, mean value; normalizing the plurality of extracted features; and, using the normalized plurality of extracted features and an input indicating sleep apnea severity to train a machine learning algorithm and generate a mathematical model for subsequent use in classifying airflow and volume sensed signals received for a particular patient during wakefulness as normal or sleep apnea.
